Something is wrong I came home yesterday after school and my computer had been restarted even tho no one was home and it was sitting on the log onto windows XP screen. So I log on and my account starts my wallpaper shows up and thats all the shows. I have no start menu, no icons nothing at all. I opened windows task manager with control+alt+delete and tried to run start menu or control panel so I run a system restore to like a month ago. But I try to open start menu and it says it isn't even a file. I put my windows xp disk in but there is no choice to reformat and I have no clue what to do so if someone can help me thanks alot.
