pc auto shut off

[Nick]

My problem is that after a while playing a 3D game (currently Enemy
Territory) my pc shuts off .. no blue screen or warning just shuts down i.e.
stops completey. I am then unable to reboot the pc until I disconnect the
power cable for about 10 seconds. I've tried ensuring that all my bios
settings are not agressive and i've even turned the settings on my gfx card
to well below the default setting.

My pc is as follows

Asus P4C800-E Deluxe
P4 2.6GHZ 800mhz fsb
1GB pc 2700
Galaxy GF FX 5900
2 * 120gb Maxtor SATA150 HD's as raid
2 * 120gb Seagate IDE 133 HD's as raid

There is also no info in any of the events tabs.

Any help or ideas welcome

Thanks

This is what I said. Sorry I didn't notice it was in a different
newsgroup. I apologize

My first thought would be overheating, but I doubt that that is really
the problem. Do make sure that the heat isn't getting too high though.
I feel the real problem is most likely your Power Supply. What Power
Supply do you have? For that system, you will probably want at least
350 Watts. That video card will eat through the power as will the
motherboard/processor. You can always buy a new Power Supply and see if
that fixes the problem and if not, return it (just double check their
return policy first)
