Ok before I tell you the problem here's a quick overview of the system...

case - ANTEC LIFESTYLE SONATA II
psu - ATX - POWER SUPPLY 450 WATT ( ATX12V 2.01 )
motherboard - ASUS P5N-E SLI
processor - INTEL CORE 2 DUO E6400 / 2.13 GHZ ( 1066 MHZ ) <-- using the fan & heatsink it came with
hdd - WD CAVIAR SE WD3000JS - 300 GB - 7200RPM
vga - XFX GEFORCE 7600GT XXX <-- this isn't installed yet, only plugged in so i can connect my monitor.

Now for the problem: I'm trying to install XP but after about a minute of the installation process the PC turns itself off.

I've never built a system before so any ideas what the problem is?

Thanks, Lee.

I suggest you get a moderator to move this to hardware. You will a lot more help there.

It's ok I went out and bought some thermal apste and applied it to the CPU and everythings fine now.
