HELPPPPPPPP!

EDIT: FIXED! I found a ps/2 keyboard and plugged it in, then I had to uninstall the update I downloaded. And then I just got the disk that came with my mobo and had to re-install all drivers -.-

I'm posting this from my phone by the way.
Ok so I used a program called live update 5 from Msi
and downloaded the update for my and shit....

When it had finished installing, the computer restarted and it has like deleted all of the drivers or something?
No external inputs on the mobo work.
My mouse isn't working, keyboard isn't working and even the lan won't work.

It recognises all of my shit when I'm booting up but when it says 'welcome' (into w7) all of the devices turn off? FUUUUUUUCK HELP ME POLEASE
