CPU Usage @ 50% with nothing running

[jsaxon2]

The problem I am haveing is that my system seamed like it was running slow. I checked the task manager and it showed the System Idle Process running @ 99%. That looked good, but then I checked the CPU Usage and it showed 50% was being used. I do not know what is using 50% of my CPU. There are no processes showing that they are useing anything. What could it be??? I have already checked for spyware and scanned for viruses. When I boot into Safe Mode, the CPU Usage is 0%. I tryed disabling everything that starts at startup and still the problem remains. Please help.

Thanks in advance,
John

Go to

and get rid of all of the services you can. Then determine if you still have the problem. If you do, then try to figure out what is using your resources out of what is left.

Are you getting hard drive activity during this time? Could be the indexing service. I think this is enabled by default so when you're not doing anything else it wanders along and indexes your hard drive for "faster access". Just a shot in the dark,

Good luck.
