You need to start eliminating causes. Try 2 sticks of RAM instead of 4, then try using your old videocard and disconnecting other non vital components.

Have you cleared the CMOS? You need to start clocking the system from scratch, 500fsb is quite the achievement. Try higher multi and lower fsb for the same speed. Also, 45nm chips do get worse over time with high VTT / vFSB. I even noticed this on my 65 quad, that would do 3.8Ghz 1.3v at first but then got a lot worse over time. This was with excellent watercooling.

Having a jiggawatt PSU doesnt mean anything, it can still have problems with that particular motherboard for example.
I will try 2 sticks of RAM instead of 4, but I cannot try my old videocard as I've already sold that...

Yes, I've tried clearing the CMOS, but only to reload "old" settings.

I will probably try to overclock from scratch, I just think it's REALLY weird that it crashes that fast.
I've never seen that in the past - either it wouldn't post or it would simply freeze when booting windows - or it would boot just fine. Never seen these reboots during harddrive detection or inside the BIOS setup.
