MagicAndre1981 Posted September 3, 2011 Author Share Posted September 3, 2011 correct. Now it is 40% CPU usgae caused by the driver. Check the driver settings and enable Interrupt Moderation and all Offload options. Also try to lower the speed to 100MBit. I doubt that you have a 1GBit Internet connection.

fluffymasterchief Posted October 26, 2011 Share Posted October 26, 2011 Hello Andre.Nice tutorial. It helped me greatly to find the source of high CPU usage.But even though I know what is causing the problem, I don't know how to fix the problem: halmacpi.dllThis halmacpi.dll is using 50% or more of my cpu for 2-3 seconds in every 25-30 seconds interval. This causes a noticeable lag or unresponsiveness in my computer whenever I am doing anything that is CPU intensive. halmacpi.dll is also a part of a window system process so I can't exactly remove or shut it off either. And searching around the internet didn't help me much for finding a solution.I've attached the screenshots of table summary. A link to the downloadable latency.etl is here: http://www.megaupload.com/?d=PNTZL0GUI appreciate any help or advice you could give me.Thanks Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted October 26, 2011 Author Share Posted October 26, 2011 the BLKWGDv8.sys indicates an issue with the Belkin Wireless G Desktop Card driver. Your driver version is 6.1061.1115.2006. So try to get an update because this driver is from 2006. Link to comment Share on other sites More sharing options...

I solved my problem I couldn't find a latest driver for window 7 so I just disabled the device and removed the driver (wasn't using the wireless anyway) and now there is no more problem!Thanks again man. Much appreciated Link to comment Share on other sites More sharing options...

Tosa23 Posted December 17, 2011 Share Posted December 17, 2011 Hello Andre! First of all thx for the great tutorial. My explorer.exe causes 50% cpu usage, but now i'm not really sure what is the problem. Maybe this comctl32.dll causes the problem, but how to fix that?Here are the screen shots and I appreciate any help from you. Thanks. Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted December 17, 2011 Author Share Posted December 17, 2011 you must load the debug symbols. Have you configured the symbolpath? Link to comment Share on other sites More sharing options...

MagicAndre1981 Posted December 19, 2011 Author Share Posted December 19, 2011 The explroer uses a high CPU usgae because of the COMCTL32.DLL!CLVItemStore::CacheItem fuction. In the callstack I see VSDATANT.SYS. From what I see this is ZoneAlarm. Try to update or better remove ZA completely.Next install the Vista Sp2! Vista Sp1 is out of support since July 2011! And also try to enable AHCI in the BIOS to get the best HDD performance. YOu're running the HDD in IDE/ATAPI mode. Link to comment Share on other sites More sharing options...
Tosa23 Posted December 19, 2011 Share Posted December 19, 2011 ZA is now completely removed, but explorer still uses high CPU usage like before, arhg... Here is the new trace(ZA removed): http://www.crocko.com/D17EFF3E962449EBAF2638514D3BA477/latency.zipAHCI is enabled in the BIOS, so im not really sure what is the problem with HDD mode.

MagicAndre1981 Posted December 19, 2011 Author Share Posted December 19, 2011 please install the Sp2 and test it again. Link to comment Share on other sites More sharing options...
Tosa23 Posted December 20, 2011 Share Posted December 20, 2011 SP2 installed, but still the same problem... New trace: http://www.crocko.com/3C7B35AEFA274633AEAD7F0E5E46B5D6/latency.zip Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted December 20, 2011 Author Share Posted December 20, 2011 Function COMCTL32.DLL!CLVView::IsCleanRectcauses 36% CPU usage. There is no docu about the function. IsCleanrect maybe GDI related. So update the graphic card driver for your NVIDIA GeForce 8600M GT. Your driver is ForceWare 176.44 (7.15.11.7644) which is very old.Try this satble driver:http://www.nvidia.com/object/notebook-win7-winvista-285.62-whql-driver.htmlor the latest Beta driver:http://www.nvidia.com/object/notebook-win7-winvista-290.36-beta-driver.htmland test if this fixes it.
