This question was asked via E-mail, but as a solution was found I thought it was worth posting it as well.
Question was:
I used Memtest to test my memory and I found a bad chip (thanks, guys!).
All other chips tested fine one by one, but when I put 2 or 3 at the same time, Memtest freezes, usually at the test 4 or 5. I tried to disable a legacy USB support, but that did not help. Any idea why would it do that? Motherboard is GA-965P-S3, memory is 4G (4 chips each 1Gb) made by OCZ, PC2 6400 800MHz.
Eventual solution was:
Replacing RAM with new RAM & problem disappeared.
Conclusion:
Bad RAM might not always be detected by MemTest86 before the bad RAM provokes a crash in the application. In this case tests 1 to 3 didn't detect the problem & the bad RAM happened to be in a location where the executable code was loaded.
