Mouse cursor corrupts, then system freezes
I've been having some problems on my desktop that I hope someone here can help me with.
A while ago I was getting system freezes that were preceded with the mouse cursor becoming corrupt. I thought it might be overheating, so I stuck Core Temp (running E6600) on my 2nd monitor, but under stress (several hours of CSS) the temp doesn't go over 62C. This was a few months ago and I hadn't noticed the problem in a while, but the other night my system froze in exactly the same way, and it's now crashed twice in 2 days. Interestingly, it only seems to crash from the desktop, its never crashed mid game.
I am planning to reinstall windows because I'm going to upgrade my system hard drive (RAIDed raptors :-D) so if it is an OS/software error the problem might go away. However, I'd appreciate any insights you guys may have.
I posted on another forum and someone suggested RAM, so I ran memtest overnight and had 80 passes and 0 failures.
Thanks in advance!
