Screeching/crackling sound from system speaker

[Karbon Killa]

Recently, whenever I try and boot up my Nforce 680i sli, I don't get any video, and my system speaker crackles at me. It sounds like I have eggs on the stoves. Just crackles and pops sound. No white smoke. Thank god. But do you guys think I may have blown my mobo?? It only happened after I installed my northbridge and southbridge water blocks. Didn't boot once I put them on. Maybe someone here can help me out.

Did you possibly scratch a trace on your mobo while mounting the gear?
Any water leaks?

I suppose you could always try to replace the factory heatsinks and see if it boots, but what you are describing doesnt sound like it would have a happy ending.

Maybe check for physical damage, or an electrical short.

I don't happen to see any scratches on any traces, only thing i can think of is when i mounted the water block, that it cracked the silicon, but i do not see a crack. There was a water leak when i was testing it, but a very slow one at the o ring. I held a towel to it, so no damage from that to the board. It just wasn't booting ever since I mounted the water blocks.worked beforehand, but after they were in, it would boot for just under a second, and then wouldn't turn on again until i restarted the psu.

Try removing components and booting as minimal as possible?

[Karbon Killa]

Tried it. 1 stick of RAM, video card, an that was it. stock cooling as well. Still no luck.

the towel could have shocked a chip.

Try no ram, see if you get the stand error beep. Not looking good though..

[Karbon Killa]

It was more like a shirt. And I didn't touch any chips with it, just the fitting area. Tried with no RAM, no error beeps. I get 2 flat horizontal lines on the post code readout, and sometimes the power doesn't cut out, but flickers. Like the leds will be flickering if its moved or slightly bumped.

I really don't know. I think it would be some type of interference

Have you tried a different power supply? If the power isnt up to snuff, you can get all sorts of weird issues.
