Once the password is entered, starting up is slower. Used to be able to watch videos through itunes, now videos freeze as song continues, sometimes itunes freezes up. Occasionally under Yahoo fantasy football, I click on a team or player, the CPU usage goes up to 100% and get a neverending mouse and have to Ctr-alt-del. Everything seems just slower in general. I've scanned using AVG, ad-aware, and use CC cleaner. I have defragged and compressed files. I heard that CPU's used to last 5-6 years and now they are faster and built to last around 4 years. I am having a "professional" come clean my wifes 4 year old Dell (also bogged down) and was told rather than waste the money having mine done, break down and get something newer. What do you think?
