PC does not spark up

[Lab_Rat]

First, the specs:

AMD 64bit 3000+ (2.0ghz)
ASUS K8N4-E
1GB RAM
Nvidia 7800GT
Maxtor 80GB HDD (primary)
Maxtor 160GB HDD (secondary)

Nothing is overclocked

Quite a while ago, we had a pretty bad thunder storm here in the UK but I thought nothing of it and had gone to bed, leaving the computer on. The next day I am awaken by my brother who informs me that he cannot turn the computer back on. (He needed some file from my comp). I popped open the case and took a look. Obviously I had not taken anything out or replaced anything because it was working fine before.

I thought that maybe the PSU had fried due to the storm, (despite having surge protective extension plugs) so I tested it in my brothers computer. It fired up with no problems. Next I thought it could be either the CPU or the motherboard. However, the motherboard light does still light up. I have replaced the CPU with a new one, and still there is no spark upon pressing the power on button. No other lights come on, no fans spin, nothing.

So now im at a complete loss. I dont know what to do next other than replace the motherboard, but I dont want to do this if its not needed.

If any other information is needed, please do ask for it.

Any advice or help would be greatly appreciated.

Thanks.

Just because the motherboard "lights up", doesn't necessarily mean it's working. I'm pretty certain you'll find it's fried.

(And yeah, those storms were pretty intense. I was going up the M5 at the time. -_- Bloody weather.)

Oh yeah, I do know that. I just wasnt sure if it is indeed the motherboard.

(lol yeah, was incredible)

The only thing that will stop it booting that you havn't tried is the mobo.

Guess my next purchase will be a mobo.

I thought these surge extension plugs are supposed to cut off in situations like this? But then, im no electrician.

Thanks for the help people.

Did you by any chance leave a USB modem or a router connected to your PC? Chances are the surge travelled up the phone lines, through the modem/router and into your PC via USB or a LAN port.

[Lab_Rat]

Yes, everything plugged in to my pc was turned on. Thats a USB cable modem and a LAN router, both of which also go through the surge protective plugs.

*edit*

I would like to know how it happens actually, quite curious.

[Lab_Rat]
