open the bios set up and set the DVD drive to boot first.
Put the win 7 disk in the drive and start the system.
This reloads the OS but does not erase your personal files and programs.
Or if you do not have the disk, a computer store will do it for you.
Thank you, I've tried this and it keeps going back to the blue screen, I also tried removing the memory and reseating it but this did not work either. :-(
