A lot of laptop and
desktop computer problems are caused by a failed memory or a failing
memory module. As a laptop repair technician I test memory modules every
time I get a laptop for repair. I have tried many different memory
testing utilities but finally I stopped on Mem test 86+. So far it is one
of the best free memory test utilities and I use it everyday. You can
find this utility on the Memtest 86+ homepage.
To test your
memory modules you have to do next:
- download Memtest 86+.
– Pre-Compiled Bootable ISO (.zip) if you want to burn it on CD.
– Pre-Compiled package for Floppy (DOS – Win) if you want to place
the utility on a floppy disk. I usually use CD because most computers
have a CD drive and it’s much faster to start the test from a CD disc.
- Change the boot order
on your computer to boot from a floppy drive or from a CD/DVD
- Insert the
floppy disk or the CD disc with Memtest 86+ into the computer.
- Start the computer.
If you did everything
right, you computer will start from the floppy or the CD and the memory
testing utility will start automatically.
If your memory passed the test, you will not see any red error
I usually allow a memory module pass the test 4-5
times. I’ve seen many times that a failing memory doesn’t fail the test
on the firs pass and then fails on the second or third pass.
If your memory
failed the test you will see red error messages.
