I have been running a some basic programs overnight lately. Uses about 3 gigs of ram and 10 CPU usage. Temps for everything that hwmonitor can see are around 30c or lower during the evening. Each night i have comeback and my screen has a bunch of random colors on the screen and the programs are all in different sizes/scattered in different places. Everything is unresponsive until i turn of the computer with the external button. When i turn it back on after the restart everything seems fine. Any advice?

Graphics corruption would lead me to suspect the graphics card.

What was the GPU temperature?

What programs were running?

What graphics card driver version are you using?

Does Windows 7's Event Viewer show anything that may give you a hint as to the cause?

344.11 driver for a gtx 780ti

unfortunately it doesnt show anything besides me holding the power button down for 5 seconds..

I was running ESET, battle.net, hearthstone, geforce exp, creative cloud and razer synapse.

i have it liquid cooled so normally it runs around 25-35c depending on what im doing.. Sense it crashed in the mornings i couldnt check it then.

GPU (Graphics Processing Unit - i.e. the graphics card)

Are you saying that your GPU is being liquid cooled? If it is, how are you cooling the graphics card's memory?

Sorry read that question wrong on my phone..

My GPU is not being liquid cooled. It is the ASUS GeForce GTX 780 Ti DirectCU II so whatever came stock with that. runs around 30-50c while using it during the day. 40c being when im playing games.

Could it perhaps be the PSU?
