laduch Posted April 20, 2008 Report Share Posted April 20, 2008 I found a interesting phenomenon long time ago... When my computer ran slowly with no reason, I opened Windows Task Manager, it displayed the CPU Usage was around 80% -100%.However, it suddenly decreased almost as soon as the Windows Task Manager is on!Is that a kind of virus or something?

andsome Posted April 21, 2008 Report Share Posted April 21, 2008 Same here, except that after a few seconds the usage fluctuates between 2 % and 0 %. :D Quote Link to comment Share on other sites More sharing options...
