...is a sign that it's NOT just the monitor, but the entire system is hanging, which even if you say it's not under load when it happens, still indicates a possible overheat situation, probably on the CPU.

Hello,
I have problems with my pc/screen turning off after 5-30min being on. I am using alot of SketchUp V-Ray rendering and that may be the cause. It happens randomly with or without any load on cpu/gpu. My pc stays on (led lights and fans only) but screen turns off. I tried recording with webcam to see if my pc still works after the screen turns off, but when it does, my webcam stops recording too. I don't know what is the problem... it started happening after I was rendering a high quality picture... what could be the problem? :/
GPU: Sapphire radeon 7970hd 6gb
CPU: AMD FX-8350
Motherboard: ASUS Sabertooth 990FX R2.0
Power supply: 750w
RAM: 2x4gb
I tried switching to other rams, but it didn't work.
