All I have is a 42" Clock! Keyboard and mouse not working.

Ok, the keyboard and mouse are both usb. Ive tried other types of keyboards and mice... Don't matter. Its not recognizing them when it gets to the space needle clock screen. Or even for that matter as soon as Bios is done booting. I am able to get into the bios screen no prob and mouse and keyboard work there. What do I do? Had this sh*t for a day and downloaded my games last night and bam I restart PC and bam, Windows 8 Hates me! Oh I hit Activate on windows update. That was the last thing i did.

Well it seems that now I cant even get into Bios.... Keyboard blinks and I spam delete.... Nothing. Computer loads so damn fast that its hard for me to get a moment to hit up the Bios. Ive thought about complete re-install but it doesn't even pick up the disk! I'm kinda at a loss.
