I am running windows XP, it came with software already installed on it for my hewlett packard scanner. However the software that was on the new computer didn't have the copy utility and some other features I had on my old computer which has windows 98. So I loaded the software that came with my scanner onto the new computer with the CD-Rom. BIG MISTAKE now the computer reboots every sixty seconds. I did uninstall the software but still can't do anything. Computer just keeps rebooting.
