First off, I have a: Acer Aspire 5532AMD Athlon Processor TF-20 1.60 GHz3 GB RAM64-bit Operating SystemWindows 7 Home Premium (When I purchased the laptop it already had Windows 7 installed) Now the problem is, the CPU usage is 100% the majority of the time. If I open anything such as, iTunes, FireFox, IE, etc.; the cpu meter is at 90-100%. From time to time I would have like just iTunes on and it I would say "lags" as in the mouse doesn't move smoothly, like it moves, stops, moves, stops, slowly..? I can't really explain how it acts, but I guess slow. Sometimes when I don't have any programs running, the meter goes to 100% anyway. I have no viruses what so ever; I had just recently bought it. Is it due to battery options? (high performance, battery saver). I can't seem to find the problem. I'm pretty familiar with how a CPU works but not as much. Help?
