I have a computer that has win 2000 running on it and it is a 400 mhz processor. But the problem is that it is running at 100% cpu usage. The thing that is causing the problem is the process system which is right below system idle. It takes about 30min to 1hr to boot up and then when you click on anything it takes about 1min to 10 min to open. But I don't know what under system is causing the cpu usage to run at 100%. So maybe one of you can help me find this out.
