I went to bed last night and I left my computer on as always. I woke up this morning to find it shut down. It turned out that my PSU got fried sometime during the night. I went ahead and bought a brand new Antec 550w and installed it. I plugged the power cord in without plugging anything else in just to check if the motherboard wasn't damaged. All was well so I plugged everything else in and booted into Windows.

That's when I noticed that my internet connection wasn't working. There was no LAN icon on the taskbar showing that a cable was unplugged. I checked device manager only to find out that Windows did not find any ethernet adapters. The drivers are installed but there's no ethernet adapter. I updated the drivers and all, disabled/re-enabled LAN in BIOS, still nothing.

Then I checked the ethernet port. The speed LED is off. The ACT/Link LED is always orange. Whatever I do it's always orange. As soon as I plug the power cord in it lights up. Even with the ethernet cable unplugged it's still very orange.

Does that mean that my ethernet adapter is damaged? Please post any thoughts you might have. Thank you.


Specs:

Asus P5LD2 Deluxed motherboard (onboard LAN - Marvell 88E8053)
Pentium D 820 2.8Ghz
2Gb RAM
NVidia GeForce 7800GTX 256Mb
Audigy 2
Antec 550Watt PSU
 
I had a similar thing happen to me during a storm that overloaded my phone lines. My PSU survived but the ethernet connection that ran from the phone line to my modem fried. Maybe something similar? Or maybe when it fried it knocked out something on the mobo?

Does your modem still work? (I'm assuming it does as you posted this...)
 
My modem wasn't working either. It would turn on but there wouldn't be any connection. The LEDs would blink but that's all there was to it. It was replaced before I replaced the PSU. I've googled it to see I can find something similar with no luck :(
