|sounds like your power supply may be faulty, or the battery is dead.|
Try removing the battery and see if it boots up properly. Try the same with the ram, if you have 2 sticks, remove one and try. Then just use the other one to see if at least one ram works.
Why would you be using that resource hog Norton? That is beyond me.
