Need help with black screen

[Distoration]

Well i just Updated my computer with more Ram,PSU, and a new video card. But 5-10 mins into playing wow the screen goes pitch black and i have to turn off my computer manually and started up to work again. Does anyone have an idea what it is? My Monitor is about 5 years or older. Sorry if i did't post alot of info on computer.

Sounds like something is overheating. Or it could be graphics card crashing. Post temperatures (following stickys) and update graphics card drivers.

I've Updated the graphics card drivers.
With out the game on the temperature is 71 c and gpu 70 c
With the game on it is at 73 c and gpu is 72 c.

and its getting higher

Temps aren't useful until they've reached their max. So "its getting higher" doesn't help.

[Mr.hey]

hmm.. I had similar problem before. That was because of the fan, which was too dirty...:P. So I cleaned it and the problem never came out from then on.

Those temps look too high.

Like the max temp my cpu can handle safely is 73* c.
