Hello there!!

So the other day a massive electrical storm passed through the place I live and a lightning hit extremely close to my house frying everything electronic that I have.

Fortunately I had a UPS connected to my computer and also it was powered off. However, the network adapter of my motherboard was fried :/ (everything else working fine).

My problem now is that after that lightning every time that I shutdown my computer it restarts!!!
Even if I press the power button before windows load (so it's not a windows problem).

I tried tweaking some stuff at my BIOS (stuff like power up through network etc) but still nothing.

My motherboard is a Gigabyte GA-990XA-UD3 powered by a CORSAIR VS550

Any ideas?

You could check the BIOS and make sure the power is set to remain off after power loss, but you probably need to RMA or replace the motherboard.

Modem lines and NICs are still connected by copper, if it wasn't routed through the UPS for isolation as well, it remains a point for damage to occur. The best protection is to simply not be connected, however.

If the NIC was fried, I'm assuming the router took a nasty hit too.

The funny thing is that the router works just fine!! Is this possible?? I had another computer connected to it too and that one fried completely (both psu and motherboard).

The option for the power is set to remain off like you said in the BIOS.
If I update the BIOS is there any chance that it will get fixed?? or will it get worse?
Also, if I continue powering it off from the PSU switch (after the windows shutdown/restart) is there a cause for concern? Can it get worst?

I don't think a BIOS update can help you. You can't fix hardware damage with software or firmware. Powering it off by the switch isn't going to cause more damage.

If the board is under warranty, I would see if you can RMA it. But I wouldn't count on a warranty covering damage from lightning.

Most likely you need to replace the board if you want this issue to go away, whether it costs you out of pocket or you're lucky enough to have warranty coverage.
