Hello,

I have a problem whit my computer that I do not know how to fix. Some days ago my graf-card died and I was forced to buy a new one. It came down to GeForce GTX 285 XXX from XfX. But when installed and every thing looked like heaven itself, it turned into hell.

When using my computer to surf on the internett or play games like Battlefield 2, Eve-online etc it works fine. But when I try to play Assassins Creed, Crysis or Call of duty 4 the computer turned itself off like some one pushing a light swich. No bluescreen, no logging off message... just the empty black screen.

To fix this I tried to flash the Bios and update it. I tried to reinstall the graf-card drivers and also to remove some of the HD to free W from the PSU. When I first tried removing the HD, Crysis worked fine untill 5 min into the game, and the computer turned itself off again.

I talked to the local shop, and they have taken a look, but did not find anything wrong. I hate to send my computer back to the shop so I'm hoping to get some help here. All the games I have worked fine on the old graf-card a GeForce 8800 GTX.

My computer is a self-made one from 2007. (My friends and I think that my PSU have seen it's best days and is not giving out 750W anymore, and that I currently are running the computer almost at the PSU max output. So when ever I try to play a game the new graf-card needs more power and therfor the computer turns itself off)

But do anyone els have a better idee?
