Hi guys

I am facing a queer problem. I was watching a movie on my PC as usual when suddenly it restarts out of nowhere. Now, before even reaching the BIOS it restarts again. This restarting cycle continues until I turn off the mains.
(When I turn on the PC, light turn on and fans spin for about 3 seconds and then they turn off and again start spinning after a sec.)

As of now, I have tried only these -
- Resetting CMOS jumper
- Removed the GPU

Specs-
CX-430
i3 3220
1TB WD green hd
GTX 460 Hawk (out of cabby right now)
4gb ddr3 ram 1333hz
1 exhaust fan and 1 intake
Mobo - H61MU3

This is the first time I have faced this problem. PC had been working just fine until that moment.

I would like to add that my UPS is ageing and sometimes (I think most of the time), in case of a power cut, it would restart if the GPU was at load. I know that's not a good thing, but I doubt it helps as I haven't noticed any effects of those power cut restarts (until this??).

Still trying other options.

So any ideas anyone ?
