Changing CPU in socket 939 boards?

Bought my brother the following system:

Asus A8V Deluxe
AMD 64 bit 3000+
512MB PC3200 Geil memory (one stick)
eVGA 6800GT AGP
Raidmax 400W PSU

Assembled the complete system, turned it on (lights turned on, fans spun, sound like hdds spin up), but it wouldn't POST. Checked to make sure video card had power, CPU fan was properly connected, memory stick was in correct slot, changed PSU as well. Computer just wouldn't POST.

So I tried my processor in his computer (AMD 64 bit 3500+) and it still wouldn't POST. Eventually after restarting many times it did POST, and began to boot into Windows. I immediately turned off the machine and installed his processor and then computer wouldn't POST.

Even went as far as putting the 3000+ in my computer upstairs (Gigabyte board, can't remember specs) and I couldn't get it to post at all.

Is there some sort of trick to changing processors in a socket 939 board? I've tried clearing the CMOS (removed the battery, jumped the pins) and that didn't work. Very frustrating!

Why a raidmax 400w?!
with a 6800gt?

Shouldn't be a problem. I have an Antec TruPower 380W that kept up just fine.

I have now gotten the computer to POST and now it keeps restarting during POST. Initially says my processor is overclocked. I Load BIOS Defaults in Setup, Save changed and Exit. Computer will restart, POST, and then randomly restart again.

Going to try my Antec 380W PSU to see if that changes anything.

Does it sound like a motherboard problem?

Well if you tried the 3000+ in your own pc it shouldve posted. Busted cpu maybe?

If should have, but why wouldn't my 3500+ post in my brother's pc? Works perfectly fine in mine.

He didn't point out your PSU because it was 400W, he did because its a Raidmax. Get him a REAL PSU, like an Antec or an Enermax.

I second that.
 
Ditto on the Raidmax is a POS. But if you've already tried swapping for a real psu, then I'd say it sounds very much like the standard metal touching the motherboard problem. Take the motherboard out, put it on the anti static bag that it came in on top of some non static surface, intstall only the absolute minimum needed to post the system (ideally cpu, cpu fan, 1 stick of ram and the least power consuming video card you have) see if it will post reliably. If it does you mounted it in the case badly.
