No beeps eh? If you get beeps, you can at least figure out what they mean. but, if you're powersupply was pooched, I think it can let too much into your mobo and kill a few things. Maybe you even had a power surge that affected your PS and motherboard. You can get a new mobo pretty cheap, if you can find one that matches your gear. I would just hope that nothing else (like vid card and ram) got fried.
