whoops sorry about double post.....anyways i tried turning on my computer on and off after a bunch of internet pop-ups plauged my screen but when windows tried to boot it came up with this: "windows could not start because the following file is missing or corrupt: \WINDOWS\SYSTEM32\CONFIG\SYSTEM" "You can attempt to repair this file by starting Windows Setup using the orginal Setup CD-ROM."
SElect "r" at the first screen to start repair.
