No POST

I can't seem to get my computer to post now after changing the motherboard, cpu, and ram.

Heres what I did:

Uninstalled drivers etc from old mobo/gpu
Turned off computer and power
Opened up case swapped different motherboard (asrock alivenf6p-vsta)
Put in 1GB of ram, installed processor, mounted heatsink, and connected IDE drive.
When I press the power button I hear and see(left side of case open) the hsf spinning, but nothing else, not even a beep.

I made sure all power connectors were in securely, reseated the ram multiple times, nothing.

Does anyone have any idea whats wrong? Atm im using onboard video.

running on:
Asrock AlivenF6P-VSTA
FX62 with stock heatsink
2GB DDR2-800 Crucial Ballistix, also have tried one stick alone and i've tried a stick of 1gb ddr2 wintec ampo ram.
OCZ StealthXStream 600W
80GB IDE Hard Drive
ATI 3870 (havent used this, planning to however)

So, I can't get this damn thing to post! Any suggestions would be greatly appreciated.

edit: if the motherboard shorted, would this be a symptom?
edit2: I tried turning it on again after reaseating the processor. I left it on and the heatsink spins but the power shuts off after about 10 seconds.
edit3: tried it with 3870 with no avail....

Try it outside of the case, on a cardboard box...

/*------------- <cut n paste> -------------*/
If you have both the 20/24 pin main ATX connector plugged in, AND the 4-Pin (or 8-pin) ATX12V P4 CPU connector plugged in, then the board should boot fine (unless it requires more power connectors from the PSU). You could try clearing the CMOS.

You could test the PSU. Jump start it (on the main atx connector, short the green wire with any black wire, using a paperclip), and see if it stays on. If not, then its probably a faulty PSU. If it works then you can proceed with the suggestions below. ***NOTE: The paperclip trick is a simple test for those that do not have PSU testers, multimeters, nor a spare PSU to test with. It is not a 100% conclusive test of the PSU.

Setup everything outside of the case, with the mobo on top of its cardboard box. Plug in only the essentials:
- PSU (namely: main 20/24-pin ATX connector and 4-pin ATX12V P4 CPU Connector)
- CPU w/ HSF
- Single stick of ram
- Videocard if there is no onboard video (along with its power connector, if it has one)
- Monitor
- Keyboard
- System speaker/buzzer

* Use a screwdriver if your board doesnt have an onboard power switch. Jump the two power switch leads to turn the power on.

If it won't post, try different RAM slots. If it still won't post, pull out the ram (so no ram in the system) and listen for error beeps. If none, pull the vidcard and listen for error beeps. If none, re-seat the CPU and HSF, then try again. Report back with results if you're still having issues.
