Hi there,

Had a scan around the forums, couldn't really find anything specific so here's hoping some might pick up on this.



My computer here is having trouble in that DPCs and interrupts are causing large CPU spikes every minute, this increased when media (songs and videos on WMP, iTunes) and graphically-intense games are played.

Did a little research and found a program showing me that the DPCs are running a little slow on each other causing latency;

Disabling my USB wireless network adapter does seem to stop the latency so it would seem to be network packet related, transfer between OSI layers maybe.
So now I'm stumped, I'm unsure of where to begin with these DLLs and their related handles or what devices to check. It does seem to be network related but I'm not sure what I can do to fix it, or what this NDIS.sys file is and why it's creating the majority of the problem (50+ milliseconds of the stuff). Does anyone have any experience with troubleshooting this kind of problem?

HDAudBus.sys (\SystemRoot\system32\DRIVERS\HDAudBus.sys)
netbt.sys (\SystemRoot\system32\DRIVERS\netbt.sys)
portcls.sys (\SystemRoot\system32\drivers\portcls.sys)
rdbss.sys (\SystemRoot\system32\DRIVERS\rdbss.sys)sthda.sys
sthda.sys (\SystemRoot\system32\drivers\sthda.sys)
tcpip.sys (\SystemRoot\system32\DRIVERS\tcpip.sys)
TDI.SYS (\SystemRoot\system32\DRIVERS\TDI.SYS)
USBPORT.SYS (\SystemRoot\system32\DRIVERS\USBPORT.SYS)
ntkrnlpa.exe (\WINDOWS\system32\ntkrnlpa.exe)
NDIS.sys (NDIS.sys)

I found these with another program called "RATTV3" which monitored handles that were causing this lag, gave me this log (I've removed insignificant entries that were only adding up to 1-100microseconds of lag, there is a total at the bottom.

I've also included various related hardware and system specs below.

Thanks,

Samm

It looks like the wireless usb driver could be bad, have you tried updating the driver.
id also make sure i was at least at sp2.

also, have you changed any setting from default in your bios

Yeah pretty sure it's the main cause of the problem but I'm hoping for alternatives for solving the DPC issues through tweaking.

It's SP3 and bios hasn't been changed.

I've also tried using Interrupt Filter to change they way device drivers use individual CPUs, no success so far.

Tweaking might not be possible unless it was tweaking that started the issue, i would still change the driver to see if that made a difference, also malware on a system can casue funny issues, i had a friend who had a rootkit running that the only thing he noticed from i t wsa certain games would spike to %100 cpu

Ah sorry forgot to say, big problem is that I can't as there isn't another update yet for the Linksys WUSB300N :thumbsup: rollbacks don't have an effect either.

When I say tweaking I mean of the DPCs and interrupts, will have to keep researching.

Thanks for the advice.

next two things id try is to update the motherboard drivers

also go into the bios and see if there is an option for plug n play (pnp) with the options bios or os, and change them to os.
