Well just started getting that prompt here and there. No bsod just the prompt on my screen when I came down this morning to the machine. I ran memtest 86 for 5 passes , no errors Heating not a problem, 35 idle, 50 under load xp pro sp2 I'll attach minidump and any suggestions would be great! Don't want to really dump money into this machine unless I have too. Edit: Thought I'd go ahead and attach the other 2 minidumps in my folder here. Thanks again.
