Her USB outlet was broken and she couldn't get the computer to boot up. Someone from Dell came out to assist her. He replaced the outlet, along with the mother board, and memory stick. The computer fired up just fine and he left. However, he didn't try and do anything with it. She was able to log into Windows (Vista) twice, but both times, the system froze almost immediately upon login. Now, she can't get the keyboard to respond to actually log on to Windows unless she boots in safe mode.
I haven't had a chance to look at it myself, and apologize for not being able to provide more detail, but I wanted to post here and see if anyone had any suggestions as to what the issue might be now. I'm hoping to try and get her up and running sooner than Dell can come out and look at it again, so any ideas I can arm myself with going in would be appreciated.
