100% CPU usage ...

daandi 6 years ago updated by Support (Developer) 6 years ago 1
Hi here...i am new here and have a question about something that makes me wonder.

Sometimes the performance graph in the system explorer shows up to 100% CPU usage, but the processes tab only shows some (3-5) which are over 3-5% usage, the rest shows 0%. But I trust more the performance graph, because the temperature and the fan go up in the situation.

How could I find out what application, driver or else causes the high usage?

thank you

First check the Performance>Processor... Do you have DPC/Interrupt/Privileged Time high?

If you find high DPC..then you can try http://www.thesycon.de/eng/latency_check.shtml

You could also try to enable Windows Event Tracking in the options and check which processes uses Disk/Network access... or try to order processes by IO activity..
