PC goes black when playing a game.

Today , for the first time, while I was playing a war game with many graphics, the screen suddenly went black then the PC turned itself off. Does anyone know why this happened. Every time I try to play that game the same thing happens now. I've updated the driver for the graphic card and everything else is up to date as well. I have no viruses or malware. It only seems to be happening when I use the graphic intense game because otherwise I can get online and Email just fine without it going black.

Anyone know why this is going on??? Oh, I get little black lines on my monitor every so often as well now. Little disruptions on my screen. Thank you for any ideas about what's going on.

I'd say either the card is overheating, the power supply is failing or the card is dieing.

You could test the first possibility by downloading these two programs:

http://www.cpuid.com/hwmonitor.php
http://downloads.guru3d.com/FurMark-v1.4.0-download-1965.html

Keep HWmonitor open and run Furmark (set it to at least 2 minutes). If the video card temperature gets really high (like over 90C) then that's probably it.

Does it only happen with that game? Or others too?

It happens with any game that's really graphic loaded. Easier games like chess don't have any problem at all.

Classic case of overheating. I doubt this is a power problem.

1. put some fresh compound between the heatsink and the cpu
2. Make sure there isn't a mammoth sized dust bunny caked on the fans
3. Make sure there is enough airflow in the case. You need 1 fan pointing in, and one fan pointing out. I usually have the bottom case fan (towards the front of the case) pointing in, and the topmost case fan (under the PSU next to the CPU) pointed out.
4.Inspect the fan on the graphics card, and make sure it isn't clogged/dead.
