PC keeps restarting on boot up

As the title says really, my PC keeps restarting when I boot it up.

I'll get the normal Gigabyte S-series screen, then it flashes to the black screen momentarily that shows all the controllers etc, this is all normal, then at this point it restarts all over again, I think this is the point where XP normally kicks in .

Any suggestions on trying to diagnose the problem.

GA-965P-DS3 mobo
X1900 XT
Geil DDR2 pc6400
Intel Core2 1.6
can't remember HD

btw I can't even get into safe mode as it restarts immediately the menu option shows up

Things have gone from Bad to worse, I left the machine rebooting over and over while I left the room for a while, when I came back the screen was off and the PC was on with the fans going, but nothing else, not even restarting itself.

Not even keeping the PC button depressed for 5 seconds switches it off, and when I do restart it from the mains power, the PC lights and fans come on and that's it, nothing on the screen at all, no beeps nothing.

So I can't test anything, I made sure nothing is lose in side etc.

Everythings out on the desk, I reconnected GFX, CPU/fan, RAM, monitor.

When I switched the power supply on the CPU and gfx fans started up, this is the same problem. The monitor shows nothing, doesn't power up or anything, there is no beeping from mobo either. Not sure how to turn on/off mobo manually, is there a link or detailed explanation, I'm currently touching each of the outside pins (3 pins) of the power on the F-panel with screwdrivers.

Thanks

I asked at work and they have no compatible componants for me to test with.

Is standard warranty 1 year, I can't find anything on the Gigabyte site for RMA's and overclockers don't stock it anymore, I suspect it's the motherboard, but I bought it Sep'06.
