why cpu extremely slow and cpu usage = 100%?

Hello thereI am having problems with windows vista. According to the windows task manager's performance tab, the cpu is running all the time at 100% usage. However, when I check the processes' tab I do not see any process that is consumming all these CPU resources. The pc is running extremely slow. However it is a core quad.In case that can help to find the root of the problem, please find the screen shots for the windows task manager in:<a href="" target="_blank"></a><a href="" target="_blank"></a>May be it has to do with a virus that is running a hidden process. Does anyone have any idea to solve this?Thanks

And yes I've read "It worked before" many times. Follow my line of thought at 7723-6122_102-510824.htmlwhere we went from trying to overclock the machine to regain speed to trimming out titles that we find to conflict today.

Yes, those used to be OK.

I Start Cleaning Things Up Like This

Some of what you're experiencing is normal.. Indexing and other background processes constantly run and a few glitches can cause the CPU to use a lot of its resources.

First, start by reducing the amount of unneeded programs on the computer by simply uninstalling those you don't use. Next, reduce the amount of files stored on the computer by emptying the various Temp and Temporary Internet Files folders.. You can use "Disc Cleanup" (Start-All Programs-Accessories-System Tools-Disk Cleanup-Cleanup System Files button-More options tab), to eliminate all but the most recent System Restore points as well.

After that, run a good malware removal tool to eliminate any unseen malware.. The free tool below should help:

SUPERAntispyware Removal Tool

Once that's done, eliminate any unneeded startup programs and services by using the System Configuration Tool (Start-type "msconfig" (without the quotes at the search line), then press "Enter" and click on the "Startup" tab. Once there, uncheck any unneeded startup programs. If you have any questions about which programs to UNCHECK in "msconfig", post back, or check for yourself at this site:

And after all of that, run Defrag and Error Checking/Chkdsk using the link below:

Hope this helps.
