How to get the cause of high CPU usage by DPC / Interrupt

[Patyfatycake]

Edit: Latest Xperf.

My fresco logic drivers are already the latest.

Fresco Logic xHCI USB3.0-3.5.100.0

Which matches the website

Also i managed to solve the high isr I believe by getting a certain wireless drivers(I will confirm this when i get home from work and get you a latest xperf).

which issue do you have? The DPC usage is below 1%.

The regular CPU usage from audiodg.exe comes from the USB audio device (USBAudio.sys!USBMidiInGetCurrentTime).

well very rarely my mouse gets disconnected from the USB now(i cant get an average its that rare) and my gfx card is jumping around 500, is that quite common?

Thanks for your help.

from what I see from the trace the system is now ok. What do you mean with the 500?

My nvidia drivers were jumping to around 500, Il keep monitoring it to see if happens again.

Thanks again for your help.

I still have no idea what you mean with 500? 500µs? This is still ok.

Yes 500µs.

[MagicAndre1981]

500µs not very good but still ok.

Been having the same issue for some time. NDIS being annoying, I think. It wasn't a particularly bad period and the analysis is not long but there you go...

Xperf: https://www.mediafire.com/?sj3jkjb66dyjuez

And a capture of my LatencyMon: http://img801.imageshack.us/img801/6572/fqly.jpg

the trace is corrupted, close LatencyMon before running xperf!

[Andunemir]

Sorry about that. Sorted now...

update the Wifi drivers:

"NETwsw00.SYS", "15.1.1.1"

the latest version is 15.9.0.4.

Updated and restarted. Fingers crossed...

It is annoying the Toshiba website kept saying all my drivers were up to date. That's why I kept thinking it was more a driver incompatibility than an out of date one.

[Andunemir]

The update didn't work but somebody else told me AVG was faulting netbt.sys. I had tried stopping it before since I had read there were conflicts and it didn't work, but uninstalling it completely did the trick. Had my computer running for a couple of days and still no sign of trouble.

[MagicAndre1981]

yes AV suites can cause this. But this is hard to see from the trace.
