Computer won't Reconnect to my Router

[Jongamer]

EDIT: Grrrr Friggin' windows Updated my LAN driver without telling me, THAT is what cause it, all I had to do was do a Driver Roll back.

A Mod can Delete this thread if they so desire.

Ok, So I was just sitting there playing Fallout 3 on my computer, when it Blue screened, wasn't able to catch the error in time before it rebooted.

Well I turn the computer back on, and ran a Diagnostics on the HDD, since the computer has been acting weird since I Installed Windows on a Newe SATA drive.

Well the Western Digital quick scan hangs around 8/10ths of the way through the quick scan (says should only be a 2 min scan, but I sat there for 8min to see if it would progress any.

Then after Install a bunch more Windows Updates, and order something off newegg, RIGHT after the transaction went through BAM, internet connection died, none of the web pages would load, Thing at the bottom of the screen say "limited to no connectivity" All the other computers in my house could connect just fine.

Reboot the computer, nothing, Tried connecting my computer directly to the router instead of through a switch, didnt help.

Please Help, this is a brand new computer and I REALLY dont want to come to the conclusion that the Motherboard's Onboard NIC died, cause Newegg doesn't sell this board anymore.

I am about to power cycle my router, but doubt that is gonna help since all the other computer connected to the router are doing just fine on the internet.
