Hi, Im running a A8N-SLI Delux mobo,AMD Athlon 64 3800 cpu, 1 GB DDR SDram, XP Pro, 650 Watt psu, and a brand new GeForce 8800GTS graphics card. The comp runs fine until I start playing a game, after a few minutes the whole comp just turns itself off......help

More than likely to be overheating.

Check the CPU temperatures. Check that all the fans are running correctly.

Sounds like a over-heating problem - have you checked all fans are spinning up correctly and that your pc has a good clean air-flow throughout front to rear.

Thanks, yeah all the fans are working fine, do you think it could be a lack of power???

With a 650W PSU power should not be a problem.

If you have only just installed the Graphics card, it might not be seated properly - I would remove it and then make sure it is re-seated firmly in place.

Talking Power - the GTS needs a single connection to your PSU, is this in place? (The GTX needs a double connection to the PSU).

Yeah the power lead is connected, there is a pci card directly under the graphic card and seeing the card is so big there's hardly any room between them, may-be thats causing it to get to hot.

If it's only done it after fitting New Graphics card, try the old one to see if it cures the problem

Have you got a spare PCI slot, if so it might help to separate them a bit.

OK...Thanks alot, i was worried there wasn't enough power but there must be a over-heating problem somewhere. This is a great sight, thanks for your time and trouble.

Also, has the CPU been touched lately, I'm thinking Thermal Paste - could be the CPU getting too hot.
