In task manager, nothing is using more than 4% of the CPU but when I look at performance its CPU is running constantly between 60-70%

When music is playing it jitters about every 2 seconds and the mouse stops and starts.

Any ideas? I havent installed anything recently and the virus scanners havent picked anything up.

Its a Dell Vostro 1700 running Vista, 3 years old (Never had this problem before)

Ben.

I dont know why but iuts cured since its been switched off overnight, I updated BIOS, Chipset, GPU drivers yesterday and it restarted / shut down loads of times but still didnt cure it. Wonder if it was a temperature thing, the fans werent running fast though...

I'll never know.

Check the fan filters for 3 years worth a dust slowing the air to aid cooling.

Fans will come on if the processor is working hard.
