CPU使用率低, but my PC work very slow

Do you have a lot of program using inactive. INACTIVE
They spend CPU usage a lot invisibly, even though they don't need to.

For example, anti-virus software, or others....

Because no matter how much ram and memory you got, if you run many programs and software together, it is slow for sure.

You can try task managers to delete some useless programs or raise the instant memory higher. go to control panel - system - advanced - you will see there's a number of memory you could spend, like 360MB - 720MB, it's using the hardisk as assistance.

Or you might have virus, for unusual cpu activity. slow your pc down for no actual usage.

extremely slow...?

how and when it preformed slow...?


If the items move on the desktop is slow (w/ shadow),

it should be the display card driver not correctly installed...
