My aunt brought her computer to me and said "I think it was struck by lightning. Can you get it running again?" I said, "Sure." thinking that it was the power supply. We ordered a replacement power supply and put it in. The power supply receives power, the green light on the back lights up. So i tested to see if it would turn on. Still, nothing. I thought "hmmmm, maybe it's the front panel assembly which houses the power/usb/audio stuff." So, we ordered a replacement part for that. Still, when I hit the power button nothing happens. Fans don't turn over or anything. Is it possible that the motherboard itself is fried? Now, I'd like to disclaim that this particular computer has been plugged into three different outlets, all of which pass the lightbulb test. The chords I'm using do not have shorts in them and should be functioning properly. I really want to know how likely is it that the motherboard itself is shot. Has anyone ran into this problem before? Simple solutions?

Was the computer outside, HAHA! The motherboard is probably fried, try another and get back to me. If the original power supply was a stock one, it probably didn't take the charge and passed it on to the motherboard. Tell your aunt to ALWAYS plug in electronics to a surge protector

Lol. Appreciate the rapid feedback. I'll order a replacement motherboard and try it out. One additional thing I did was pull the battery out of the motherboard for ~30 seconds and put it back in. Still nothing. I have a question about the mobo that I order though. It should be the same model as the one currently in it , right? 'cause Dell builds their computers around the motherboard and a different one may not match up with the case.

Mobo (motherboard for short) have standard sizes, so yes, order the same model to ensure the same size. You will also need to re-install windows to prevent any issues that may come up using the windows already on the HDD.

Alec, I've already thought about that. Before I make anymore purchases on parts I plan on explaining the situation to her. I have no problem with doing the work. As a CS student I enjoy the experience this offers, thought I am not aware of the "extensive damage" that you speak of. Would you care to elaborate on that? Mainly so I can relay the information to her. I've never had a computer crap out like this. Usually the PSU and/or front panel assembly takes care of the issue.

Ask your Aunt if the computer was on during the strike, If so all parts receiving power at the time of strike will have some damage, if the computer was off, the mother board probably took the brunt of damage during the strike
