my dell inspiron 5100 laptop with xp pro keeps rebooting with a message "warning this operating system was developed by professionals and/or total idiots. In either case, microsoft or you and or any of your buddies should not expect this software to run without crashing... and has picture of skeleton skull. It comes up when you select xp boot screen in the o/s screen. Everytime i try to run kasperksy antivirus on it the pc turns off. I can't even load another operating system or format the disk coz it turns off each time. Any advice? Thanks.
