Hi, I've noticed this past year my computer has significantly slowed down in speed. Does anyone know any tips I can try, I am searching up Google but they don't seem very helpful. Also my computer does not turn off properly. I.E. I click Shut Down, then it says "Saving Settings", then it does that and reaches the black screen. After the black screen it stays there and I can move the mouse. To turn it off I would have to push the power button for about 10 seconds. This has occured for hte past month. Anyone have any help on this topic too? I own a Windows XP Home Edition, Pavilion PC. Had it for about 3 years and warranty ran out which means I can't get over the phone help either. Some one please help me!
