Unreliable random-access memory (RAM) can lead to a variety of problems with your computer, including corrupted data, freezes, and strange, inexplicable behavior. Speaking or corrupted RAM can be one of the most frustrating computer problems as the symptoms are often random and difficult to identify. MemTest86 + is a useful tool that can be downloaded on a CD / DVD or a flash drive and helps diagnose faulty RAM. It is often used by system builders, PC repair shops and PC manufacturers.

Method 1 of 2: Using MemTest86 + with a CD / DVD

1. Download Memtest86 +. Memtest86 + is an open source program and can therefore be obtained legally. The official download site is http://memtest.org here. However, make sure not to confuse it with the original MemTest, which is now outdated.
2. Double-click on the zipped file. Inside you will find a folder with the title mt420.iso. Drag this file to your desktop.
3. Right-click on the file and select Open. Don't forget to put a blank CD in your computer to download the program.
4. Select a program from a list of installed programs. Then choose Windows Disk Burner. Windows Disk Image Burner will now open. Select "Burn".
5. Restart your computer. MemTest86 + will run automatically when the computer is restarted if the CD option is shown first to boot. You can set this by pressing F8 on most computers.
6. Run the program. You have to run MemTest86 + seven to eight times to ensure accuracy. After it's put in slot # 1, switch to slot # 2 and repeat. Do this until you have had every memory slot.

Tips

• If the computer will not start, try using another computer if one is available and compatible with the RAM type. However, if the computer won't boot due to a PSU error, have a computer shop test the RAM because trying to do it on another computer can cause the RAM to damage the computer.

Warnings

• Never remove RAM while the test is running. You could be electrocuted or damage the RAM.
• If you are removing the RAM to replace it (and are knowledgeable about computers), be careful about removing and replacing the RAM. RAM is fragile!
