It's not hardware...the ONLY thing that crashes is explorer.exe...It's a new build and I'm always monitoring temps (hence Core Temp.exe in my HJT).

My CPU never goes over 63C on full load, GPU doesn't go above 75C usually, and the case sits between 100-115F usually (37-46C). It's definitely not hardware related, or power. I've got this desktop and my server on the same UPS and the server NEVER has issues. I know it's software, but I don't know what.
