Powering Down

This isnt really a vray problem…I cant render anything that takes over a couple of hours it seems. I crash, burn, you name it… If I try and render a file over night or over the weekend…When I come in the next day, my computer is off. No blue screen…Just off. I have ran the memory test and everything was fine, so I am at a loss. Could I have a bad power supply, motherboard, etc..etc..

Stange happenings

This is definitely a hardware problem…
You may be overheating as the rendering is 100% cpu usage, so
if your MB has some C.O.P (CPU Overheating Protection - ASUS had such one), it may just turn off the PC, when some temperature is reached.

Check out all your vents, powersupply, videocards, etc.

and/or disable any Protection from the Bios, where possible…

This may sound stupid, but it’s possible the cleaning service or coworker is shutting it down (found the cleaning people doing that on mine once).

Or, if there’s a power outage/surge (bad wiring, lower voltage at night, etc.)… get a UPS to fix that problem.
