Hey, i have had this problem for the past 3-4weeks, I currently have an amd FX -6300 six core processor 3.5Ghz, and my computer continuously shuts itself down while playing games and rendering from maya. When rendering from maya the cpu usage is 100% so im presuming they shut themselves down before overheating, but while playing games like diablo 3 and dayz standalone only 1 core seems to rise as high as 90+%. then inevitably after afew hours the computer shuts down again. im a computer noob so any advice or help would be appreciated. i have scanned for virus' and defragmented my harddrive already. there is some dust on the inside but other than that nothing visibly wrong. this alll started happening after i started rendering from maya 3-4 weeks ago.
