So I've had friends over the last two days and right before they came I installed a new WD 640 gig HDD. So I had it sitting downloading stuff when all of a sudden the power crashes. well since i had friends over I havent gone back to it now. And when I turn it on all the fans come up, psu comes on, hdd's run and cd drive runs but I get no video and no post and no beeps from the mobo. I'm thinking the motherboard is fried. what do you guys think? and if so is there a chance any other stuff is fried?
 
You'll have to do some HW troubleshooting. Start by clearing your CMOS. Then try another PSU. Then try pulling one stick of RAM out. If none of those work, you could start stripping it down to barebones. Having parts to swap in and out would be a good idea, if at all possible.
 
well i took out everything essential and i still couldnt get a post or beep. I Also tried another psu but its from a linux box and is severely underpowered but i assume I would get a beep still even so. I also tried different ram from my rents computer
 
Sounds like a dead motherboard to me. No beeps = no go. Take out the memory and boot it up. If you don't hear a beep it is most likely your motherboard.
 
take out the vidcard, too. you should definitely hear beeps with no vidcard/ram. however, also make sure there's a system speaker plugged in or onboard, lol.
 
there is a system speaker plugged in, no vid card/no ram=no beeps. But talking to a friend I recalled the comp did turn off after the lightning storm but promptly froze and I shut it down. after that, nothing.
 
then i'd try another PSU (not the same underpowered one you tried earlier). though, it is possible that the storm killed the PSU, which killed some other components, namely the board.

even if the psu fan etc spins up along w/ all system fans and drives? doesnt make sense to me

A PSU thats been through a T-Storm having enough power to spin a fan but not turn on a computer doesnt make sense to you? :eek: FYI, it doesnt take much to power fans compared to a whole computer system. I'm not saying that your PSU is the problem, I'm just saying its a possibility.
