I've had my acer aspire 5101AWLMI for almost two years, and it's always worked fine, at times it was a bit slow, so I upgraded the given ram (1gb) to 4gb (the accepted maximum). However, recently A new problem has developed. Sometimes when I run a program (it can be anything from a full-screen high-spec video game to a tiny browser-based flash video) My computer becomes really slow, until I minimise it. I checked on task manager, and my CPU usage jumps up to 100% when the program or applictaion is open, and falls back to around the usual when I minimise it. It's not a virus, there are no extra processes running, just the process that /are/ currently running (espescially the one that slows everything down) take up way more of the cpu uses than normal. My processor is an AMD Turion 64 Mobile technology MK-36 (2.0 ghz, 512 kb L2 cache)Thanks in advance for any help
