Remember that not just the CPU may be heat sensitive. Try this:
1. Cover off.
2. Just one stick of RAM.
3. Latest BIOS.
4. BIOS defaults.
I've seen people with a dozen fans and still the cover off fixed it. That drives them nuts.

When i play games like battlefield or rome total war or any application mostly. i will be playing or working and then my whole pc shuts down and reboots. I thought it may have been a power problem but i had a 350 and changed it to 480 and still the problem continues. Is it maybe a hard drive issue or a heat issue.
2.53 pentium
Windows Xp
1gb 2100 ram
7 fans
480w power
radeon 9800pro 128mb
80 gb hard drive ( 60Gb empty)
I checked bios and the it said that
