Anyway, I have many many things installed and downloaded which could cause problems but run many virus/adware checks and don't visit stupid websites. My computer has been running fairly hot but rock solid for a year now after being built but the last few weeks I've been noticing CPU slowdown. Drastically. It also began shutting off unprompted and randomly. I cleaned up my hds, defragged more often, and even blew out my case/reapplied thermal paste to my proc. The system is running faster and cooler now but it is still powering off frequently. During a defrag, watching a movie, installing a program. Sometimes this happens after 2 minutes, some after 2 hours but it won't stop and i'm not sure why. I hope that by running all of the advised programs, checking for malware, and running a HJT someone may be able to tell me what is going on.
So far: I've run AVG antivirus and AD-Aware with no problems, memtest86 with no problems after 15 hours and 11 passes or so, checked running processes & any unknown programs. Because it is just shutting off with no warning or message or during a specific program, I'm wondering if it's hardware related but again, I'm hoping I can get a hand here. Thanks in advance and I'll post again after running more tests.
