Lightning struck our house about a week ago and even though my desktop PC was plugged into a new surge protector that I had just purchased two weeks earlier, the lightning fried my power supply. I know it was the lightning because I was using the computer an hour before the thunderstorm. I turned off the computer, then the lightning gave us a power-outage, then we got our power to the house back in about 2 hours, and then my PC wouldn't turn on.

If I leave the switch to "I" on the back of the PSU, the green light bulb on the motherboard flashes, but I still have no power. I'm assuming the PSU is dead, but is there a way to find out if the motherboard is also bad now?

P.S. I hooked up my internal hard drive to my laptop and all the data is there.
 
The PSU is out, you've pretty much established that. Try a different one and only then will you know if the motherboard still works.

Does anything spin up or light up when you attempt to start the computer.
 
Can someone suggest a PSU for me? :confused: Everything you see listed on my signature is what is being powered by my pc. Except for having a Logitech C920 HD Pro webcam and speakers that are powered on their own, I can't think of anything else that needs power that I have attached to it. I'm gonna try a new PSU instead of going the multimeter route because I don't have a multimeter anymore. I thought I did, but I can't find it.

P.S. My 550 watt power supply - someone on CF once told me it was a rubbish PSU and something about 12V rails and stuff I don't understand - and that there are power supplies out there rated for less watts that would be better for my pc because of the whole 12V rails thing or something like that. I'd eventually like to upgrade my AMD quad core CPU to an AMD 6-core CPU, if I can find one new, and I'd also like to add a SSD drive eventually. So, I just want to make sure everything is sufficiently powered (but I'm not a gamer).
 
Yeah, it was rubbish. Anything from Corsair is good. Anything OCZ ModXStream and above is also fine. A 600W will power your system good.
 
Seasonic is best of all. Some Corsair are Seasonic made while the rest is CWT made which is ok but not really all that good.

The difference between good and bad PSUs is how they handle surges, brownouts and blackouts. My Seasonic survived a lightning storm. I had a brownout and my PC turned off. I thought I blew it but all it did was shut off the system. It's fine.

Seasonics are worth the money and they come highly recommended.
