Here's my problem. I am getting random lockups for just doing nothing. For example, typing a paper in MS Word, or surfing the internet. The weird thing is when I run benchmarks such as 3DMark looped, Quake 3 Looped, Sandra Burn In, Seti all night long or CPU Stability Test it won't ever lock up. I have come to the conclusion that it has either got to be a PCI card, or my fsb speed. When it locks in Word, or on the internet I can still move my mouse, but if I try to click on something, or type something my motherboard makes a buzz sound. Does this suggest anything to you guys what is locking up? Correct me if I am wrong, but I believe if I can move my mouse, that it isn't my cpu or video card. I know it is not my memory, I have already tested it at higher speeds on another board, and Benchmarks suck as 3DMark, and Quake 3 are very memory intensive.

Thanks in advance for any help.
