Thunder Struck

I am rather new to this so please bear with me. The other day while my wife and I were away from the house there was a thunder storm here that caused a power outage. Now my computer won't post. Sounds like a motherboard to me. What do you guys think?

Probably the power supply.... A power surge from lightning will damage the AC side of a power supply a long time before it will damage a motherboard.

or maybe the psu , do you have access to another one you could try ?

it may be a good idea to invest in a surge protector

Thanks for the quick return guys. Would the fans and hard drives still fire up?

more than likely, it all depends on which of the rails have gone down ,try a diferent psu if at all possible ,you could also remove the cmos battery for 30 secs and allow the bios to default and see if it will boot

Thanks pebbly and CommonTater. I Reset bios installed different psu. First attempt was a no post. I then removed video card and tried again. To my surprise the thing posted. Reinstalled video card it posted again. Was feeling brave by then so I tried my original psu it posted and loaded windows. Thanks for push in the right direction.

Great that you got it working.

I saw this thread too late, but in case it happens again...

Before you rip out the PSU, unplug the AC power cable at the back of the PSU for a few minutes and then plug it back in. Some PSU's have a resettable fuse in them which will only reset in the absence of voltage/current. Unplugging it for a little while resets it and you're good to go.

It's worth a try before you start pulling things apart.

And like pebbly said, think about investing in a good surge protector.

When crap like this happens, as a rule of thumb, I do what the poster above me states. Disconnect everything, and I also take another step to reseat cards. You just never know!
