A Dell Inspiron 9300 laptop
Intel Pentium: 1,73GHz
Since yesterday my computer is slowing down a lot.
Pretty much any action causses a slow-down of 1-2 seconds. If I have iTunes running in the background the music starts to stutter as soon as I as much as click on a file.
When I check the CPU usage and applications I notice something very weird. If I don't do anything the CPU-usage is around 0-5%, all pretty normal.
However, if I start up a program or click on a file the CPU usage sky-rockets up to 80-100%.
Looking at the applications doesn't help me much either since it doesn't seem to be one application in particular that eats all the CPU. All applications are generally at 0% unless I use a program, then that program suddenly uses up all of the CPU.
I really have no idea what could cause this sudden slow-downs, I can't remember downloading or installing anything yesterday.
Anyone have any suggestions what I could do?
