My CPU goes to 50% used for no reason and screen gets choppy

[ADE]

Out of no where, my CPU goes to 50% used for no reason and my computer lags just when moving the mouse! Its so random though! what could be going on?

Check out Svchost in the task manager. Svchost is a program in charge of some of the processes your computer runs, like avast or spywarrior. You're going to be looking for either many instances of it running (10+) or a large Cpu/memory consumption. The same thing happened to me after downloading a certain program.. i had to uninstall it to get my system to work correctly.


If it isn't svchost still check the task manager to see which process is causing the the CPU problems.

if you see scvhost not svchost, its a virus.. that might be causing it too

Open up system manager and check out the processes that are running, and see if you can find suspicious ones.

Better yet download hijackthis and post the log.

It might be down to a recent bug documented in the media; it's been caused by an update and causes the svchost.exe file to run at 100%, however ADE has 2 cores so XP only utilizes 1.
