I was not using it for a little while and when I tried to turn it on recently it said that it could not find my signature for Windows XP and would not log me in. So now I am stuck and can not get in. I went into safe mode and tried to do a system restore and nothing happened. It is an older computer and on its last legs but I gave it some juice so I could play games on it. Anyone know what is going on here. I do not have the exact error number but I can put it on later. Am I screwed?
