So I decided to slap the reinstall disk in and do a fresh reinstall of the OS. However, when the machine boots up, I get to the screen with the revolving logo then a blue screen pops up which reads:
"Your system has been shutdown to prevent a fatal error. If any new hardware was installed, remove it and try again".
It also advises to do a virus scan, which has been done to death. I can only get the computer to boot if I select the recovery option when rebooting. What's going on and how can I fix this?
