Light on mobo is lit, press start and fans try to go but stop immediately.
Connected to mobo-power. power sw, speaker, pled& hdd led's.
Removed mobo to look for possible shorts, found none. No wires beneath mobo.
I don't know how to determine if the psu or momo or what eles is defective.
Any help would be appreciated.

I posted this in another thread:

What's the mobo?

Are these connected?

4-pin cpu fan
4/8-pin cpu power (by the cpu)
24-pin mobo power (by the ram)
2 x 6-pin gpu power (on the gpu)

Double check the front panel pin connections. It's detailed in the manual.

If all check out, and no power on, clear cmos. Refer to the manual for how.

If that still fails, disconnect everything and remove the gpu, take the mobo with cpu & ram out of the case onto the mobo box, insert gpu, hook up all mentioned power connections, remove all front panel connectors, switch psu to on, short the POWER/PWR jumpers with the tip of a ball pen.

If that still fails, you can try clearing cmos for 1 hour to overnight. As a last resort, rma mobo back to store for replacement.

But I suspect it's your mobo's bios that doesn't support the cpu. I have had a AMD build that exhibited a similar behavior. If that the case, your only solution would be pay a store to flash the bios for you.

Believe it or not, I read and tried everything on the site that I could find without buying test equipment.
So, I bought a PSU tester and found that my OCZ PSU was DOA.
RMA'd the OCZ PSU and bought a Corsair.
One reason that I decided to build a computer was the high level of help available and, when the new PSU arrives, I will test it before installing it. Hopefully, the computer will boot.
I realize that those who provide the help get frustrated by the same rookie problems.
Your help IS appreciated and is the engine that drives this site.
Thanks
