100% CPU RRS feed

  • Question

  • Hi, i really don't know anything about computers but i really need some help! My laptops been really slow lately, and i know that having high CPU can slow down your computer. So i checked the CPU and its pretty much always between 80%-100% which im guessing is why its been so slow! The main contributors are System Interrupt (about 40%) and avp.exe (about 30%) I was wondering if there was any way of cutting them down or anything i could do to just stop my CPU being so high!! And im sorry but my computer vocab really does end at CPU and Programme! So it would be helpful if anybody could break it down in easier terms so i can understand!! Thanks in advance!

  • Hi,

    make a xperf trace [1] to diagnostic the DPC / Interrupt issues. Please upload the etl file to your SkyDrive [2] and post a link here.

    I'll take a look at it.

  • Hi André,

    I am doing this now! However, i've found that the second i disconnect from my internet (i take the lead out from my laptop) my CPU drops to about 20-25, and that System Interrupt completly goes from my CPU usage.

     

    Could that be the problem?

    I am at University so i share the internet with hundreds of other people, but when i first arrived this wasnt the case, my computer ran fine. Its only been recently.
