My Son was trying to correct a problem on our internet home page, with the help of our internet server. The last thing they told him to do was to try to run the computer from a previous date. When he restarted the computer it has two selections to start from Windows XP and C\:from a previous date. From there asks how you want to start and it go's to blue screen saying to reboot, check for viruses ,ect. At the bottom it says Stop: 0x0000007b(0x9f89640,0xc0000034,0x00000000,0x00000000). I tryed to start in safe mode to normal mode and it keeps going back to the blue screen. I have since renstalled Windows Xp. Could you please help.
