I get spikes of 100 % on task manager in windows 2000 even when no programs are running. Also get frequent 50% usage for long periods with no apparent programs running. Is this indicating a possible CPU problem? New system.

Your screen saver takes a lot of your CPU resource if you run it. Disable it and observe if you still have the spike. If you still have, there may be some other applications running in the background while the computer is idle. You may have to disable them.
1. Do Registry editing (Regedit).
2. Back up your Registry (File | Export).
3. Go to Hkey_Local_Machine | Software | Microsoft | Windows |CurrentVersion | Run and delete any subkeys (programs) on the right pane that you do not need.

I would recommend delete all of them and observe. If there is no spike, you know one or more of the programs are the culprits. Restore (File | Import) the original registry and then delete one program at a time to isolate which one.

Some antivirus programs may scan the hard drives while the windows is idle. If this is the case, disable the feature and observe.

To backup whole registry, please refer to Microsoft Knowledge Base Q322755.

I take it that you are leaving your task manager run all the time to see this, or are you just monitoring it for certain times during the day? You may have a application running in the background that you are not aware of. Are you on a dial up modem or cable(or such) that you are always connected to the internet. If you are always connected it could be your e-mail being checked that is peaking your usage.

Clear Your Tray:

Take a look at your tray. More likely than not most of the new Systems in market have at 10,000 different put in tray for your (so called ) Benefit. Get rid of them one and all.

once that done, Loook at your Services, some of them like dns Client can be a real drag. Stop them temporarily or turn them manual.

Last but not least, get hold of Cacheman. Its a freeware from Outer tech

It will let you control and observe a wider variety of issues like threads, GDI reosurces etc.
