Hello all, hopefully I can find some help here. Now, I know by the title, it sounds like a pretty easy answer, but it goes a little deeper; let me begin. So, I get a desktop that running well after my laptop ends up going on the fritz. I have the desktop for a total of about 10 days, and then this happens. Early one morning, three lightning bolts hit, maybe a total of five minutes. I was sleeping during it, so I didn't even know. It wasn't even supposed to storm or anything. I wake up, hit the power button, nothing. Try a few more times, nothing. Switch power cables, again. I call up my dad and tell him the computer isn't booting. He tells me he heard a pop in my room in the morning, but didn't thing much of it. I feel the modem and it's fairly warm. I take off the screw, pop it open, and find out a part inside blew up (the ISP guy said voltage regulator, I believe). I figure my motherboard is fried, as this did happen once before on an old Dell. The desktop and modem were connected through a surge protector, but the phone cord wasn't. This is where things get weird... Neither the phone cord, nor the ethernet cable had any burning or damage. No other devices plugged in were effected, including my phone, which is fine. I open up the computer, and there's no visible motherboard damage. I was figuring it was either a PSU or motherboard issue (duh) but I can't narrow it down. The PSU shouldn't be effected, since it was plugged into a surge protector and the modem was the only thing really damaged. I unfortunately don't have a way to test if the power supply is alright, as our only other desktop left is pretty old and I don't think it's power supply could sufficiently power the problematic desktop. I do know this problem is more of a 'test and narrow it down' type problem, but all I can do at this point is hope somebody has some advice. Thank you!!!
