Hey, my system has been crashing, blue screen of death and system reboot style. I've sent at least five error reports to microsoft, (yeah, that's how desperate I was) and they all say that the cause was an unknown device driver. I've tried uninstalling and reinstalling the drivers, using the driver cleaner and reinstalling using the most updated drivers, I've even reformatted the drive and started from scratch, same problem. Oh, I also tried clearing the CMOS, still no luck. The system always crashes when too much RAM gets used at the same time, i.e., having a lot of windows open, or running a high-level game. I have four 512s of RAM, so I don't think it's a matter of not having enough RAM. The odd thing is, that if I take three out, and leave one in, the system runs fine and doesn't crash at all, it doesn't matter which one I leave in. Can anyone think of doing something I haven't tried yet, or should I just write it off as a hardware failure and return it? <br />
<br />
P.S. the mobo is a evga NForce 4<img src="/images/smilies/gunner2.gif" border="0" alt="" title="Gunner2" class="inlineimg" />

What you need to do first is make sure that all of your memory modules are fully seated in their socket. Once you have verified this you need to run MemTest86. MemTest86 is a DOS like program that runs outside of Windows. First run it with all you memory at stock and you will see the errors fly I am certain. Then just occupy one dimm at a time with one of your 512MB memory modules to isolate the culprit(s). At least one of your memory modules is likely faulty.

I used memtest, and it gives errors when there are multiple modules in the slots, but not when there's only one. could a software problem cause issues with memtest?

Have you tried each one individually? If so, try them as pairs too to see if you can replicate your success or errors.
