Asus P4C800E Deluxe, 1024 Kingston memory, ATI 9600 Pro, Soundblaster
Audigy 2 ZS, one SATA Seagate drive, etc. and so forth... Temps are ok
and I ran a short test of the memory with memtest and it was ok.


MemTest86 sometimes won't catch timing errors... try the
Prime95 client from Mersenne.org. It's a bit more
sensitive (ideally, it should never show a SUMOUT or
other error) to issues like timing (e.g. chips that test
okay at CL 2, but still show errors until you back off
to CL 2.5).

Which may or may not have anything to do with your
particular problem.
