Windows Task Manager shows CPU usage in red, need a help.

hi, my cpu is P4 2.6GHZ, 512 mb ram, windows XP. the PC is less than 2 yr,

when i hit Ctrl+Alt+Del keys, the Windows Task Manager shows my CPU Usage in red, not normal green, sometimes in 100% usage even i wasn't running any application. ever since i got this PC, it was very slow and it would take a long time to load any application.

damaged CPU or over heating CPU?

  1. Did you try scanning for malware,virus,etc?

    I personally had success fixing a similar problem by scanning with Trendmicro.

  2. Red is used by Task Manager to show the amount of CPU that is spent executing kernel code (ring 0). Green is used to show the amount of time spent executing user code (ring 3).

    A healthy system showing both will show the green on top of the red.

    You can turn off showing the kernel time by going to the Performance tab and, under the view menu, uncheck "show kernel times".

    If once you've done that it is still red, you have a situation I have not run into before.
