I was trying to speed up a friends laptop, so I ran Superantispyware free. It found something like 400 threats, but when it removed them and restarted the laptop, the keyboard and pointer stopped working. This is windows vista and I tried to restore to an earlier check point but it keeps encountering an error no matter what restore point I choose. The pointer and keyboard work fine in bios. The only option I can think of is re-installing windows vista, but I have no disc for this. Please help as I look like a real idiot now and was only trying to do a favor.
