Hey E521 experts!
It's been awhile and I'm sure you've all moved onto better hardware, but I need you help.

I used this thread to do my E521 upgrade but ran into a serious snag with the CPU. I tried upgrading from a 3800+ to the Brisbane 5800+, stock heatsink, added 4GB Kingston Value RAM to 6GB total, XFX GT 240 GPU, 2TB hard drive added to the bottom bay.
I upgraded the BIOS to.11 as well. Pulled CMOS to reset the BIOS just in case. Cleaned heatsink, tried AS5 spread and rice technique. It fires up ok, about 3 minutes in the CPU fan gets faster and faster, then the PC shuts down. HW monitor shows the cores going thru the roof but the chip and the heatsink are cool to the touch. When I reboot, the machine can't even load Windows, just shuts down shortly after POST. BIOS and Windows report the 5800+ correctly. I reseated and reapplied AS5 dozen times or more.
Suspected video card and ram, went back to stock on both, same issue. Replaced power supply (400W Dynex), same issue.
Is the CPU defective? Am I missing something? Thanks very much for the help!
