Computer memory aka RAMBad memory can cause an assortment of different issues on your computer. Below are just a few of the possible issues you may encounter. It is important to remember that the below issues can also be caused by more than just bad memory.

  1. Computer does not boot, and you are getting a beep code. See the POST and beep code page for additional information about them.
  2. Random computer crashes causing BSOD, General Protection Fault error messages, Illegal Operations, Fatal Exceptions, etc.
  3. Random computer reboots.
  4. Windows or other program installation failure.

Note: Before testing your memory, if you have recently added any new memory into the computer, we suggest you temporarily remove it to make sure it is not the cause of your issue.

Software

  • There are several software programs available that are designed to test your computer’s hardware, including the computer’s memory:
    Windows Vista, Windows 7, and Windows 10 have a Windows Memory Diagnostics Tool that can be accessed by clicking on the Start Orb and typing “memory” in the run line. Running this command opens the Memory Diagnostics Tool with two options: “Restart now and check for problems” or “Check for problems the next time I start my computer.” Choosing either of these options runs the computer through a memory test the next time it starts up.
  • Memtest86 – Our recommendation for testing computer memory, Memtest86 is an x86 compatible, free memory tester.
  • DocMemory – Another great software solution to test the status of your computer’s memory.

Below is a listing of some other great products for you to check out.

Memory testers – Companies offer different hardware solution for testing computer memory. These are the highest quality methods for testing memory, but likely only to be used at a computer service center because of their cost.

PC-doctor – Another fantastic, but not cheap solution often used by service centers and technicians to diagnose computer hardware issues including memory issues.

PC Diagnostics –
Another company that offers both hardware and software solutions for testing the majority of computer hardware in your computer, including memory.

Ultra-X – Another great collection of products that can help test computer hardware, including memory.

Swap and remove memory

If you have access to compatible memory from another computer, you can swap that memory into your computer to see if it’s the issue. Using memory known to be functional in a computer that may have a memory problem is a good method of checking.

If your memory works in another computer without issues, you’re likely encountering a motherboard, PSU, or other hardware issue.

Replace memory
If you have found the memory to be bad, we suggest replacing the memory with new memory.

The two main categories of processors are 32-bit and 64-bit. The type of processor a computer has not only affects its overall performance, but it can also dictate what type of software it uses.

32-bit processor

The 32-bit processor was the primary processor used in all computers until the early 1990s. Intel Pentium processors and early AMD processors were 32-bit processors. The operating system and software on a computer with a 32-bit processor is also 32-bit based, in that they work with data units that are 32 bits wide. Windows 95, 98, and XP are all 32-bit operating systems that were common on computers with 32-bit processors.

Note: A computer with a 32-bit processor cannot have a 64-bit version of an operating system installed. It can only have a 32-bit version of an operating system installed.

64-bit processor

The 64-bit computer has been around since 1961 when IBM created the IBM 7030 Stretch supercomputer. However, it was not put into use in home computers until the early 2000s. Microsoft released a 64-bit version of Windows XP to be used on computers with a 64-bit processor. Windows Vista, Windows 7, and Windows 8 also come in 64-bit versions. Other software has been developed that is designed to run on a 64-bit computer, which are 64-bit based as well, in that they work with data units that are 64 bits wide.

Note: A computer with a 64-bit processor can have a 64-bit or 32-bit version of an operating system installed. However, with a 32-bit operating system, the 64-bit processor would not run at its full capability.

Note: On a computer with a 64-bit processor, you cannot run a 16-bit legacy program. Many 32-bit programs will work with a 64-bit processor and operating system, but some older 32-bit programs may not function properly, or at all, due to limited or no compatibility.

Differences between a 32-bit and 64-bit CPU

A big difference between 32-bit processors and 64-bit processors is the number of calculations per second they can perform, which affects the speed at which they can complete tasks. 64-bit processors can come in dual core, quad core, six core, and eight core versions for home computing. Multiple cores allow for an increased number of calculations per second that can be performed, which can increase the processing power and help make a computer run faster. Software programs that require many calculations to function smoothly can operate faster and more efficiently on the multi-core 64-bit processors, for the most part.

Another big difference between 32-bit processors and 64-bit processors is the maximum amount of memory (RAM) that is supported. 32-bit computers support a maximum of 3-4GB of memory, whereas a 64-bit computer can support memory amounts over 4 GB. This feature is important for software programs used in graphic design, engineering, and video editing as these programs have to perform many calculations to render their images.

One thing to note is that 3D graphic programs and games do not benefit much, if at all, from switching to a 64-bit computer, unless the program is a 64-bit program. A 32-bit processor is adequate for any program written for a 32-bit processor. In the case of computer games, you’ll get a lot more performance by upgrading the video card instead of getting a 64-bit processor.

In the end, 64-bit processors are becoming more and more commonplace in home computers. Most manufacturers build computers with 64-bit processors due to cheaper prices and because more users are now using 64-bit operating systems and programs. Computer parts retailers are offering fewer and fewer 32-bit processors and soon may not offer any at all.

First Year Free
The first exciting bit of news is the one that has been swirling around the internet all day, and that is, for the first year of its release Windows 10 will be free to upgrade to. So if you have Windows 7 or 8 you will be able to purchase and install Windows 10 free of charge. Once it is installed you will be receiving the same support as someone who purchased it. A free OS upgrade is a pretty huge deal; normally OS will cost you a little over 100 dollars. I know a lot of people were resistant to Windows 8 based on its Metro look, but the good news is that they combined the old school feel, and the new metro look into one nice smooth UI.

Cortana
Another great little tidbit is that Cortana is going to be coming to Windows 10 as well. If you are unaware Cortana is the Microsoft version of Siri. As it stands Cortana is already a stronger version of the software than Siri, and they have gone to great lengths to make her voice more fluid and human-like. They will be docking her near the start menu and can use it for voice and non-voice related functions. It will be a fun little feature that might make life a bit easier for people.

Spartan
Microsoft has gone to great lengths to make Internet Explorer a good browser, but to be honest it is a rather looked down upon browser. People love Chrome and Firefox, but it looks like they are scrapping that project and moving over to Spartan. Spartan will be taking on the role of the default browser and is looking very solid. They have made the browser cleaner, faster, and more resistance to the average spyware and virus.

Gaming
Microsoft has gone to some great lengths to make gaming more enjoyable, including streaming the Xbox one to your Windows 10 device. That means you can play your Xbox one from your tablet, phone or PC. They are also introducing Direct X12, which they are claiming will show improvements of performance of up to 50%. It also looks like Fable Legends will be set up for cross platform play. As well as the games and improvements on Direct X12, Microsoft is going to make it easier to view and store clips of video games. There will be a default folder for it and can be quick accessed at any time. I think they made a lot of good steps for PC gamers here!

Holographic Headset
Last but not least, they showcased their holographic 3D headset. It reminds me of having Jarvis from Iron Man and Google Glass; with it you can see holographic images and doing wireless computing with it. There are no limits to what people are going to be able to do with this tool.
Microsoft covered a lot of really great information which will likely shape the future of the operating systems and computers for a long time. With Windows 7 hitting the end of its natural life and going to extended support, now is a good time to join the new OS which will likely be amazing!

This document contains information on what to do you if you are not getting any sound out of you computer speakers. These sections should be followed in order because they are written in such a manner that you may identify your issue through the process of elimination.

Desktop speakers turned down
This step may seem trivial, but problem-solving works best when you start with the basics. Verify that the volume knob on the speakers is turned up enough to produce a sound. Almost every pair of speakers with knobs will increase the volume by turning it left to right, otherwise known as clockwise.

Laptop speakers turned down
If you are using a laptop computer with no external speakers connected, make sure the volume is turned up by using controls on the keyboard. They may buttons (as shown in the image to the right), or a secondary function of another key; generally indicated with blue text and activated by holding the Fn key at the same time.

Make sure volume in the software is also turned up
An important aspect of sound on a computer with external speakers, is that it is primarily controlled by software. For example, if the volume is lowered or off in the software settings, it doesn’t matter how high the knobs on your external speakers are turned up; the speakers won’t produce sound. Therefore, users should verify the sound settings in the software are properly turned up.

Mute is on
Another common mistake is for users to accidentally press the mute key on their keyboard. To check if mute is turned on, look in the lower right-hand side of your desktop screen for a symbol resembling a speaker with a “no” sign (shown right). Speakers are not connected properly

Laptop computers
If you are troubleshooting a laptop computer, skip this step since you cannot verify the laptop speaker connections.

External desktop speakers
Sound devices connected to the computer have different cables and therefore use different ports. First, check that your speaker cable is properly connected to the sound cardon the back of the computer. As seen in the picture to the right, the sound card has multiple jacks. Speakers must be plugged into the Line Out connector, which usually indicated by an image of sound waves with an arrow pointing out. The jack itself is usually green in color. If your speakers connect through USB, plug them into any of the USB ports.

Tip
Even if your speakers have worked in the past, still check the connection since it is not uncommon for cables to be pulled out of place.
Ensure the power cable is connected to the back of the right speaker, or in some cases, the subwoofer. Most speakers have a small LED (light) indicating if the speaker is on or off. One you’ve turned the speakers on (usually by using a button or by moving the volume knob from left to right), check to see if the light is illuminated. If no LED is present, or the speakers still don’t appear to be getting power and you’ve checked the power connections, you may have a faulty power source.

Sound card does not work
Like any other hardware component in a computer, the device producing sound can fail. Make sure the computersound card works properly by connecting either another pair of speakers or a pair of headphones. If another pair of speakers or headphones also don’t work, your sound card is likely experiencing issues. See our Missing or lost sound in Windows document for troubleshooting help.

Windows speaker setup
If you are running Microsoft Windows, make sure the speaker setup is correct by following the steps below.

  • Open the Control Panel
  • Select Hardware and sound or just Sound in the Control Panel window.
  • In Windows XP and older, click Manage audio devices under Sound.
  • On the Playback tab, select your speakers and click the Configure button.
  • If the speakers still don’t work after configuring and testing them, double-click the speakers on the Playback tab to bring up Speaker Properties.
  • Verify all settings and then Test on the Advanced tab.
  • After all changes, click Apply then OK in each of the appropriate windows before closing them.

Bad speakers
Finally, if none of the recommendations above fix the problem, but connecting a different pair of speakers or set of headphones did work, the speakers are bad. It is recommended that you contact the manufacturer of the speakers or computer for a new replacement if they are still under warranty.

Why would someone want online file hosting? It allows you to do a lot of things with your files. You can store many different types of files online. It is a way to host files online and let certain people of your choosing to download them for their own use. You can have them do this via the internet or by file transfer protocol (FTP). There are many different uses for online file storage.

If you look online you will find a lot of companies that offer online file storage. You will have to pay a specified amount in order to load your files onto their site. It is a good way for developers to share their programs with other interested users on the internet. Anyone who would like to try the program can download it and try it out. Some even allow users to modify the program in order to help in its development and work out any bugs it may have. Another use for online file storage is by individual users. Let’s say that you had some very important files on your computer.

The files housed some secret information that you didn’t want to ever be seen by someone else. You knew that if your computer was destroyed or malfunctioned, you could lose the files forever. This would be catastrophic for your business or for you personally. One option that you now have is the use of online storage. You can backup these files through a secure network. No one else will be able to access the files except you. Your files will be safer if you store them online, that way when your computer goes down they will be there waiting. You can access them if you need to and when you get your pc straightened out or get a new one, you can just go to the site and get all your files back with ease. This is better than using compact disks for instance as they only have a limited shelf life and you may find they will not read when the time comes to retrieve your files. You will probably be charged according to the space your files will occupy on their server. The more files you have and the bigger they are, the more it will cost you to store them. You may also be charged for bandwidth you use which will depend on how many times you files are downloaded.

They have to charge you a fee otherwise they could not continue to provide this service as they have to pay extra fees for more storage and bandwidth use. Some websites will have the necessary tools for you to use their services. Other companies may not have these tools on their site so you may have to use additional software. You can easily learn to use this type of software, but if you have any problems, the site will give you plenty of help to solve whatever problem you may have. Online file storage can save you a lot of trouble. If you have files you need to put in a safe place, look into using online storage.

Step 1

Check your recycle bin to see if the file is still there. The Recycle Bin holds files before deleting them, thus permitting you to restore them should you change your mind. To restore a file, open the Recycle Bin, right-click on the file, then select Restore. The file will return to its original position on the hard drive.

Step 2
Stop accessing the drive. If your files cannot be found in the Recycle Bin, save or delete nothing on your computer. You will have better chances of finding the file if you don’t save anything new.

Step 3
Download program for data recovery on another computer, or another drive. Be careful not to save the program on the drive that you are trying to recover the file from. Some of the popular data recovery programs that you can get for free include Recuva, Glary Undelete, MiniTool Partition Recovery, Puran File Recovery

Step 4
Run the downloaded recovery program. Follow the basic steps.

Step 5
Be precise at what you are searching. Make sure the recovery program is searching at the disk that the file was at the time it was deleted. You can specify file type, name and date of creation.

Step 6
When the program has finished scanning, look through the result list to check if your fie is included. If you have found it, select your file and click the Restore button.

Find Resource-Hungry Programs
Your PC is running slow because something is using up those resources. If it’s suddenly running slower, a runaway process might be using 99% of your CPU resources, for example. Or, an application might be experiencing a memory leak and using a large amount of memory, causing your PC to swap to disk. Alternately, an application might be using the disk a lot, causing other applications to slow down when they need to load data from or save it to the disk.

Close System Tray Programs
Many applications tend to run in the system tray, or notification area. These applications often launch at startup and stay running in the background but remain hidden behind the up arrow icon at the bottom-right corner of your screen. Click the up arrow icon near the system tray, right-click any applications you don’t need running in the background, and close them to free up resources.

Disable Startup Programs

Better yet, prevent those applications from launching at startup to save memory and CPU cycles, as well as speed up the login process. Go task manager or press Ctrl+Shift+Escape to launch it. Click over to the Startup tab and disable startup applications you don’t need. Windows will helpfully tell you which applications slow down your startup process the most.

Reduce Graphics/Animation
Windows uses quite a few animations, and those animations can make your PC seem a bit slower. For example, Windows can minimize and maximize windows instantly if you disable the associated animations.

Lighten Your Web Browser
There’s a good chance you use your web browser a lot, so your web browser may just be a bit slow. It’s a good idea to use as few browser extensions, or add-ons, as possible — those slow down your web browser and cause it to use more memory.

Free Up Disk Space
If your hard drive is almost completely full, your computer may run noticeably slower. You want to leave your computer some room to work on your hard drive. Follow our guide to freeing up space on your Windows PC to free up room. You don’t need any third-party software — just running the Disk Cleanup tool included in Windows can help quite a bit.

Defragment Your Hard Disk
Defragmenting your hard disk actually shouldn’t be necessary on modern versions of Windows. It’ll automatically defragment mechanical hard drives in the background. Solid-state drives don’t really need traditional defragmentation, although modern versions of Windows will “optimize” them — and that’s fine.

Uninstall Programs You Don’t Use
Open the Control Panel, find the list of installed programs, and uninstall programs you don’t use and don’t need from your PC. This can help speed your PC up, as those programs might include background processes, autostart entries, system services, context menu entries, and other things that can slow down your PC. It’ll also save room on your hard drive and improve system security — for example, you definitely shouldn’t have Java installed if you’re not using it.

A part of regular computer maintenance is routinely running a Microsoft application known as “Chkdsk,” or Check Disk. Whether running Check Disk on Windows XP or Windows 7, the benefit remains equal. Most computers are made up of many moving parts that over time can accrue errors without computer maintenance. These errors if left unchecked can cause problems for computers and are inevitable for all Microsoft computer users. Simply jolting or dropping a desktop or laptop may cause physical errors on your computer. Additionally, unexpected events like a power surge or an operating system crash can damage your computer. Microsoft programmers are aware of these errors inherent in computers and have developed free computer maintenance solutions like Checkdsk that any user can take advantage of to ensure their computer runs quickly, efficiently and error-free.

To understand why computer maintenance in general and Check Disk in particular is important, a basic understanding of how computers work is needed. When a computer is booted up information from a device called a hard drive is accessed to load the Windows operating system. A hard drive is similar to the now antique floppy drives of the 90s, only with leviathan proportions. A typical floppy drive holds about 3.5 megabytes, which is about a 4 minute long MP3 file of your favorite song. A normal hard drive can hold one-hundred-thousand times more information than a floppy disk. With hard drive possessing such enormous storage capacity it’s no wonder there exists a large capacity for errors to occur as well, making free computer maintenance a part of having a healthy computer. Hard drives save information magnetically in tiny grooves that can be accessed, deleted, or modified. Much like a magnet being held too closely or old age can ruin a floppy drive, the same faults plague traditional hard drives as well. Over the years Microsoft has developed their operating systems to become better at identifying errors with computer maintenance on a hard drive as a user actively uses programs like Microsoft Outlook or Microsoft Word.

To find all errors in an efficient manner, Microsoft Check Disk can be run at schedules times or at any time a user wishes. Chkdsk scans meticulously your hard drive for physical errors and attempts to make corrections as a part of free computer maintenance to these error prone portions of a hard drive. If Chkdsk is unable to correct a hard drive error that area of the hard drive is marked as unusable. This Microsoft utility is beneficial in different ways.

1) Saves Time
Each time a hard drives tries to access, record or delete information from a faulty part of a hard drive time is wasted while the computer retries to complete a process. Running Chkdsk as a part of free computer maintenance ensures the computer knows where to record and access information, and where to not waste time.

2) Increases Speed and Stability
Chkdsk ensures that faulty sectors on a hard drive are either correctly or marked for non-use. Microsoft operating system crashes, freezes and slow downs can occur when faulty areas of a hard drive are accessed. Correcting errors as a part of regular computer maintenance before they are encountered with Check Disk makes your computer healthier and run more smoothly.

3) Line of Defense
Hard drives do not last forever. While the expiration date is hard to pinpoint, Chkdsk allows users to see if there is a sudden or gradual increase in hard drives errors allowing enough time to back-up information for future transfer to a functioning hard drive.

Run programs on an infected PC
Often times, malware will prevent a computer from running certain programs. Changing the name of the .exe file can often override this. If that doesn’t work, changing the extension to .com is another useful alternative, and the program will still be able to run in spite of the extension change.

Read installers
Even major programs can install toolbar and other unwanted pieces of software during installation. Take a few seconds to read each step to make sure you are not agreeing to install something other than the program you were actually seeking. Far too often people just push next over and over, and end up with a browser covered in various search bars that just aren’t needed. In the worst of scenarios, these can have nefarious intentions.

Lock your computer if you get up
Sick of your “friends” going onto your computer at work or home and posting things on your Facebook/Twitter page on your behalf? It’s certainly an annoyance, but an easy one to prevent. Windows + L will lock your system right away, requiring a password (if you’ve set one) to log in again.

Buying a new laptop or desktop PC can be quite confusing. Many people find it difficult to compare prices, features, processor types,etc to find the right choice in accordance with their requirements. In this post we will tell you the top
10 things to consider before buying a PC.

Usability
It is important that you first consider the tasks that you will be performing on your PC. If you wish to buy a computer for simply browsing the internet and using some online services than it might be better to buy a single core computer which satisfies your minimum requirements. On the contrary if you require using it for heavy professionalwork, then it might be better to buy a system that has enhanced multimedia options.

Operating System
Users with minimum requirements may be better off buying a Windows Starter or Home Premium version e.g. of Windows 7

Size
Some people prefer buying larger laptops for a better display screen, whereas other prefer smaller and more portable sizes

Peripherals
Peripheral devices such as printers,scanners,etc can significantly increase or reduce your price for buying a new PC. It might be better off buying a system with a DVD combo drive if you do not require writing data to DVDs

Brand
Some brands offer better warranties, whereas others offer software packages that come with the system. For example, a Dell laptop with the same specifications may be cheaper than a Sony Vio. The reason is that Sony provides many of its own software’s with their laptops which saves the users cost for buying software, e.g. a DVD burning. However, if you already have many such licensed or freeware software available, then it might be better to go for a cheaper brands.

Hard Disk
A common user may merely have to decide between buying a 120GB or above hard disk system. And IT professional on the contrary might have to decide between a SCSI or a Sata drive.

RAM
It is obvious that for more professional tasks and to run a Xeon Server there will be more RAM required than for merely using a PC for browsing the internet. Moreover, the RAM type may matter more than many people might consider.

Processor
The Processor is one of the most important parts of a system and can mean the difference between a system that frequently hangs and the one that runs smoothly. Some people might think that going for the low cost single core or Dual Core processors is a good idea but I would not recommend either of them for anyone who requires using a system for more than basic usage.

Warranty
Warranty makes up the most important consideration for people when buying a system. Having one covered with the right kind of hardware warrantee is essential and should be unconditional.
