ive been having the problem for the last couple of days and ive tried everything i know. whenever i come home from a trip or the like and my computer has been pulled out at the wall to prevent a surge, as soon as i plug it back in my comp runs for approximately 3 seconds then switches back off again and wont start up unless i pull the power then put it in again but then it does the same thing and never turns on. but the computer is still recieving power as a small light on the motherboard still shines. ive re-racked the videocard, soundcard, networkcard, ramcards, hard-drives and everything else. i pulled my comp apart and put it back together and it still does the same thing. if anyone has had this problem id like some help please...
