My Dell Inspiron went down hard after the Service Pack 2 went on it- new mother board and hard drive. Now it will suddenly reboot time and time again up to 20 times in a row, sometimes not even finishing a reboot before it goes down again. It does this on battery or power cord. Even when downloading or typing. Sometimes it just sits for awhile with 2 of the 3 greem lights on but nothing happening then it will start to come up. I do not remember if it was doing this before the Service Pack I have had so many problems for so long. I ran Spyware twice, nothing. Trojan horse? Piece of junk?
