First Amd 64 build and having power issues

[Scorpionjwp]

Ok here is what has been happening lately.
I can be working on my computer and it will shut off after a few hours. It will come back in Windows Xp pro 64bit saying to recharge a battery or switch to another outlet. The computer goes into standby mode and shuts off.

This same procedure evens happens when I have it plugged into a Apc 1000va ups unit.

Here is my specs:

Amd 3200+ socket 939 processor
Asus A8n-sli Deluxe motherboard
Patriot Memory ddr3200 512 mb
Enermax 500w Liberty ps
aquagate all in one cooling system
2x 7200rpm sata hd's

In my bios I have tried setting the power option to S3 & S1 or S3 or S1, and the same thing happens the pc shuts off.

Someone please help me with this to prevent the pc from shutting off every couple of hours.

i assume your window's settings aren't instructing it to shutdown...

the enermax liberty 500 is a great psu, but i would suggest testing each line with a multimeter (12v in particular) just incase you got a defective unit.

Look for a BIOS update?

Update to my own thread.

I did an bios update, and changed the settings in the power options for the computer. Well just see tomorrow or later today if this computer does the same exact thing as it was before, Shutting down.
