100% CPU Usage in Windows 2000, System Process
Posted on 2003-10-23
I have an IBM ThinkPad PIII running Windows 2000 Professional. A couple of days ago it turned extremely slow. I opened the Task Manager and it shows a 100% CPU Usage, mostly (99%) by the System process.
I broke down the System process using the performance monitor, pviewer and pstat and I came up with two device drivers. There are two threads that are intermittently using 100% of the CPU (about 2 minutes for one thread, then it goes down and the other one goes up for another 2 minutes, and so on). The two threads point to rasacd.sys and cwcwdm.sys...
But now I'm stuck. What should I do in order to avoid this problem? I haven't installed any new hardware so I don't see why this suddenly started happening...
Thanks for your help.
