Wont install or repair
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?
