i have a sonylaptop with windows xp pro sp2 and auto update enable it means that i have the latest patches and almost up to date system and norton antivirus 2003 (also up to date) it's about 2-3 days that my system shows a message about windows will shutdown in 60sec, and starting a countdown. i learned to stop this by "shutdown -a" but i can't solve the problem. my norton antivirus 2003 finds no virus. also i used fixblast and again nothing! i tried to use system restore and i can't , cause the system restore doesn't run! also i can't connect to internet in win xp cause dial process doesn't run too. right now i installed win 2000 on another partition and use that to solve the problem. so i have to question: 1- how i can solve this strange problem? 2- i have a backup file of my system state created by windows backup program, is it possible to restore my system by this file? (note: i can't run backup program from win xp too! it makes an error in the last step of restoring my backup file, also when i restore my system using backup program from win 200 then i can't start my system with win xp!) regards Reza
