Unhappy CPU Usage at 100%
If I am surfing the net or looking up something on the net, my computer will almost come to a stop and get very very slow, when I go to the task manager, I find the CPU usage at 100% and just stays there. When I look at the processes there are several that are high (DWM.exe (20-23%, Taskmgr.exe, FireFox.exe) but don't add up to 100% at any given time. I need to run a malware program to get going again, but it keeps coming back. It does not always come back right away and I can not isolate an one website that gets it going, I have McAfee running and updated.

Also, I don't know if this has anything to do with it, but when I re-boot and it starts up I get a message that say "Microsoft .NET Framework version 2.0 is required to continue" go to Microsoft.com/downloads and download.....When I go to the download page there are a bunch of .Net framework version 2.0's, I tried installing a couple and they all say they are already installed.

Which one should I install?

Click the start orb and type resmon Click the rsmon.exe click the CPU tab From there you can find the culprit that is sucking up the processor. Post your findings.

Joan,

Thanks I'll give it a try and let you know... I am not using Norton so the back up should not be the problem..

What do you mean by "start orb" do you mean start and run and then type "resmon"?
