CPU usage is showing 100% even when no program is running
Posted on 2009-12-22
I caught up in situation where my laptop using WinXP sp3, is showing cpu usage 100% even when no application program is running. I restarted and uninstalled several software but doesnt make any difference. In the task manager - Processes, mostly seems like explorer.exe taking cup upto 40-50%, taskmgr is also 30-40%. There are 9 instances of svchost.exe are running. I tried to close some, but then one of instance close caused the computer shutdown. I dont know how many svchost.exe supposed to be there? Although svchost.exe doesnt show much CPU cycles. There were 2 instances of CLI.exe, I closed both as those were also taking quite some cpu 20-40%.
Any help what can I do? My laptop is crawling. It consistently showing cpu is 100% used. My computer scan is running but that is too slow. It might take all night to finish up.
How can I check what is my latest registry change was made?
