Fans whirr momentarily then nought happens
I know there are similar threads around but I've looked at possibly all of them and haven't found anything useful so here goes.
I just upgraded my PC, its basically all new now with new motherboard, cpu, ram and psu as below:
OCZ 900w ModXStream
Asus P5Q PRO iP45
Core2Duo E8500 @3.16GHZ w/ Nexus HOC-9000 HSF
4GB Corsair PC2-8500 Dominator (2x2GB)
74GB Raptor 10,000rpm
Only things left over from before are my graphics card, an asus extreme 8800gts 512, and hard drives, 1x500gb and 2x320gb seagates. I upgraded because my PC hasn't been working properly for a while and I decided that replacing most of the components was probably a good idea. Anyway, the first time I attemtped to boot the fans whirred for a split second then stopped, and nothing happened. I fiddled around inside for a bit, tried again and no luck. Then I took out/re connected the CPU fan connector and it booted up, and I thought my problems were over.
It worked like a dream, I installed Vista, installed a load of drivers and then, prioriorties right, installed Far Cry 2. I played it for about half an hour of gaming bliss then the PC turned itself off. I opened it up and fiddled a bit again, and I'm back to the fans whirring for a split second then nothing happening problem again. I've tried reconnecting the CPU fan, I've removed/re-seated the RAM and graphics card several times, I've double/tripple checked every connector I can think of, last night I even gutted the whole thing out and put everything back together again, and the exact same problem occurs.
I haven't gotten around to trying another PSU yet, but seeing as this one worked once and is brand new I can't believe it is the problem. I'm guessing the motherboard is probably the culprit.
Your suggestions would be wonderful before I A) loose all my hair through stress/pulling, B) throw PC out of window, or C) all of the above.

Forgot to mention I tried a different graphics card too.
I'm thinking maybe should have just stuck with the trusty old thing rather than go for the newer model.
