I've had this problem before, and I took the easy way out by re-installing windows. Well, that fixed it. Haven't had a problem until now. I re-installed windows about a month ago just because I wanted to "Clean up" my system. I've done everything I can think of to fix this. Un-installed ati drivers, repaired windows files with XP CD, system restore. I am positive its not a faulty hardware device as I have no other problems on other operating systems. (Gentoo, Ubuntu). I've attached some minidumps (All in one zip archive). --Much appreciated. EDIT: Read how to use Windows Debugging Tools for windows. So I attached my debug log.
