PC shuts down

After about 1 hours use my new build PC shuts down and won't restart. E2140 with Gigabyte GA P35C-DS3R, 1 sata HD, 1 DVDRW, 1DVD, Geforce 8800GT, Antec 380 Earthpower.

New ram was fitted, PNY 677 and it's not overclocked.

No brass pins spuriously causing shorts, oh I also have a couple of case fans as well. When PC shuts down it won't restart until a good couple of hours PROPERLY. By taking the power lead in/out psu it will semi-boot fior 5 seconds, then power off.

Is the PSU at fault? I have tried another PSU - EZCOOL 450W but it does the same.

My old motherboard was a Fatal1ty HD-190 and that worked fine with the ANTEC, I can only assume the Gigabyte uses MORE power and is casuing the PSU to overload.

Heat is fine. The bios is flashed to the latest also.

I was writing a letter when it shut down. The temps seem ok, see attached pic, they don't deviate much from as they are now.

Yes but at least it has good onboard audio!

No, seriously it is annoying, more so since it won't reboot immediatley after a shutdown. I am going to buy a 750 Winpower PSU and see if that cures it. I have installed an uptime gadget in Windows XP sidebar to see if it is hourly or what not it shuts down, there is a few seconds before it dies completely.

I am on F8 also dokko.
