How much RAM total, and how many sticks of memory do you have?
If possible, try with one memory stick at a time and see if you can isolate the problem to one memory module. It does sound like your RAM may be bad though. Or in a worst case scenario, your motherboard could be bad.
You are making sure you're putting the memory sticks into the correct #1 and #2 slots, right? I'm not familiar with your PC but the slots should be staggered like such:
#4 -- #2 -- #3 -- #1
Yes, I'm putting them in the correct #1 and #2 slots (white pins). When I tested the individual stick I put them in #1 slot.
I just ran the memtest86 on my comp and it did not find any errors. The error appears so randomly... I guess it's going to come down to replacing RAM modules on my current motherboard and see if the error still apears. If it still appears with other ram modules then I'd have to replace the motherboard (ouch!) and pray the error doesn't appear anymore. I don't see which other part could be causing this problem other than the RAM or motherboard.
Well, if you ran MemTest on each stick individually then you can likely rule out a RAM issue. Does your BIOS see the RAM correctly? If so, then the only other issue *I* can see is with the motherboard.
Of course trying other memory modules can't hurt, and memory is cheap enough now. Perhaps try replacing your RAM with a 1GB stick, or 2 x 1GB sticks or even a 1 x 2GB stick. Good luck!
