Wont install or repair

[ZettaTeeJay]

ok, so ive just built my own computer with a friend. and we installed windows 7 and it worked fine for 3 days. then it started to not respond. restarted the computer and it wouldn't start up again, came up with a bunch of errors.

so i reformmatted and it says "windows\system32\driver\wdf0100.sdf is corrupt or missing." i've tried system repair but it won't work. it won't open command prompt or anything.

Any suggestions?

Are you using the drivers Win7 supplies, or changing some out to your own?

Best to use the drivers the installer provides, or newer which come in on Optional Windows Updates quickly after install. Then only provide any drivers missing in Device Manager from the Support Downloads webpage for that model Device. You can get help with this as it happens in the Driver's forum here.
