CPU Usage stays ~52% at idle, what gives?

by BoostedA4 / December 5, 2011 9:24 AM PST

My PC:

Lenovo T400
Windows XP Professional
2.0GB of ram (I think?)

My problem:

I got the XP Security 2012 virus the other day and went through a process to fix it found here.

I removed the virus, but now I have the following problems:

A PC that sits at 50-55% CPU usage while idling. I went to task manager and sorted by processes and the only thing running is System Idle Process at 98% or so. There are no apparent services running. I have an image but can't seem to attach it.


Restarting takes several minutes (used to take 15 secs max) and is slower to shutdown than it is to start up.

When my computer sleeps after shutting the lid, it does not awake when i open the screen nor when i press the power button to awake it.

At first it may sound off topic.

I have no details about this machine like we discussed at 7723-6122_102-510824.html

But some are forgetting that if the OS gets dinged up bad enough we reinstall. Microsoft never did create an OS repair tool worth discussing.

Looks Like You Haven't Run These Tools Yet

If you haven't run BOTH of the free tools below, please do so.. (They should find some malware items the other removal program did not.) Download, install, update, then run full system scans with both tools. Delete whatever they find..

Malwarebytes Antimalware

SUPERAntispyware Removal Tool

Hope this helps.
