New desktop boots up for 2 sec then shuts down, fix?

post #1 of 3
Thread Starter 
Hi this is a new build, I got everything setup, power up, cpu and fans spin but then 2 sec in system powers off. Stripped down everything but memory and cpu fan etc still nothing. I'm hearing a faint high pitch squeel while power is plugged in.
I rma'd first mobo because it wouldn't post, but it did run all fans and not shut down like this one. So I get new one, put it in same, only thing changed was having to put processor in and heatsink a 2nd time really... I have reseated cpu though doesn't have a lot of paste on it which I could fix, but I'm afraid that may not be the problem. Is 600w power source sufficient to run it?
Ive been out of the building world for 4yrs so I'm rusty I apologize. Specs are below.

P67A-G45 mobo
Intel i5 2500k cpu
Corsair cx600 psu
Geforce Gts 250 video card
PNY ddr3 4 gig memory

Thanks to any and all help on this!!

Did you get to the bios at all? Could be ram timings if you have set them manually. Lossen them more. Try resetting cmos so it would boot at all default.
