ahh the Blue Screen of Death. could be a lot of things. its a loong process of elimination. i build custom gaming desktops on the side. so i know the how frustrating it is when things go awry.

my advice as another member said is to start backing up your important data. then i would do a clean format/install of the operating system.

since im very local to you. if you need help on it. shoot me a PM. i can do that for you. ill even upgrade you to a win7 OS.

i got a lot of clients that come to me with this problem. the easiest and cost effective way of fixing it is a clean OS reinstall. 90% of the time some window files is corrupted. it happens over time. its one of those things that just malfunctions.
