***Memtest.


*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program.

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.
