Blown PS?

post #1 of 8
Thread Starter 
Knocked my sound card out of its PCI slot on a Crosshair V Formula. The PC shut down immediately, and now will not power up. If I hit the clr_cmos button on the back of the mobo, and then hit the start button on the mobo, I _briefly_ see a flash of power -- fans start to spin, case lighting flashes on ... but then nothing. Hit start button again, nothing. Clr_cmos button again, then start button again, brief power flash. Rinse lather repeat. I attached an older PS, but it did not have the power connections to power the mobo fully (no 8-pin EATX12V power connector). This seems to power up the mobo and sustain what it can, but just not enough juice.

I think I blew the PS. Your thoughts? Many thanx for the input.

I would say you broke the motherboard.

Have you tried to remove the sound card and boot again?

Yep, forgot to mention: removed the sound card and one of the GPUs. Seems this guy had the same problem: http://www.tomshardware.com/forum/386475-31-help-light-flashes-else. Think I will run over to Fry's tomorrow and pick up a "loaner."

It was the PS. Got a new one and systematically plugged all cards back in. Good to go.

If you have another PS laying around, plug that into your motherboard and see if it powers up.
