HP Pavilion a1101n, Windows XP home edition Bought new around 8 months ago,has been working great. About a week ago it started running way slow,I mean like forever to load or open anything. Boots up ok,shuts down ok but after boot,way slow after. Used PC doctor for windows,no problems found. I have Norton antivirus and have run scan a couple of times, no virus found. Did a system restore to two weeks before noticed problem still way slow. Any help greatly appreciated.
