Did i fry the cpu or motherboard?

Well not me but a power outage. I attempt to power up the machine and the mb light comes on and the fans on the cpu and videocard spin up momentarily and that's it. I'm thinking the cpu was fried as apposed to the mb? Anyone concure?

Piece of crap surge protector.:|

When you say "momentarily" do you mean that they spin up, then everything just dies? Fans stop spinning and lights go out?

Without some troubleshooting I don't think one can tell. Would be risky (in terms of wasted money) to automatically assume it was one or the other.

Personally, I'd start with the PSU. I'd swap in one of my spares.

Next I'd pull (disconnect) all drives and PCI cards leaving just the mobo, cpu, ram and gfx card and see if it would POST.

Might clear the CMOS too.

Hope you find it's something cheap/easy to replace :thumbsup:

The mb light stays on. The fans spin for a millisecond and stop before you can even hear them. Tried another psu, clearing the cmos and disconnecting all other components and still the same.

I've seen some setups do that if you forget to hook the CPU fan up to the proper connector on the motherboard.
But since you've tested the PSU, I'd say the motherboard croaked being the most likely scenario.
Also theres a small chance that the power button wiring in the case is bad or you hooked it onto the wrong pins on the motherboard.

Ok should the drives spin up if the cpu isn't installed when i power up on a socket 754? It seems to me they should but on mine they don't. Now it's got me thinking it's actually the mb and not the cpu.

Double checked all the wiring and everying is clean.

Well, I've never tried to boot w/o a CPU. Seems to me you should get a warning (beeps), and therefore the HDD w/n spin up.
