I am using Windows Vista premium Service pack 2 on a laptop, in the last 4 months my CPU usage has shot up and now the average is 50%, even when I am not running anything and if I do CNTL ALT DEl and windows task manager there is no process that is hogging all the CPU, also it I go into Internet Explorer the CPU shoots up to 100% and stays at 100%. But then on another day it may drop down again to 50%, it seems to be intermitting.

I put a question into the malware removal forum about 2 months back thinking it was a virus of some typ, but there was no malware on the Laptop and have only got around to posting the problem here now.

Also when the CPU is at a 100% it is slowing down applications like Word, Excel etc.

When you go to the task manager and look at services you can sort by CPU usage by clicking on the word CPU. Also be sure you have "Show Processes from all users" checked.

I have seen high CPU usage caused by Teatimer from Spybot Search and Destroy, And McAfee for example. Not usually but sometimes.

The trick is to find out what is using the CPU cycles.

Of course Word and Excel will be slow if the CPU is using all its processing power for something else (!00% usage).

It is normal for System Idle Process to run at 99% as that is unused CPU cycles.
