Make a new trace with this command:

xperf -start perf!GeneralProfiles.InBuffer && timeout -1 && xperf -stop perf!GeneralProfiles.InBuffer ExplorerTrace.etl

this captures some more data.

I have no idea. It also doesn't show me more.

Do you have programs instaleld which insert new entries in the left side of the Explorer (ExplorerFrame with the drives, network and others)? Explror is here busy to insert data in a list view. Use ShellExView to disable 3rd party ShellExtensions. Maybe this helps.

Andre! i need your help!

i found user32.dll peekmessageA

Correct me if I'm wrong, the problem is 32-bit apps in x64 system?

two programs have the same "symptoms", use 25% of cpu randomly. is a intel 2500K in a gigabyte z68a-d3 drivers update!

here you have the route of one of the programs, HDTach

I can't help you. HDtach.exe causes the high CPU usage but without debug files (http://en.wikipedia....ki/Debug_symbol, http://en.wikipedia....rogram_database) I can't see the cause. The user32.dll function receives Windows messages:

http://msdn.microsof...3(v=vs.85).aspx

so the tool seems to use them heavily and runs code while handling messages.

What do you do with the tool?

1 thing I can see is that you have some DPC spikes caused by the USB Gamer mouse driver (MS1Filter.sys).

HDTach is a HDD benchmark, a little bit old..but good.

I can dispense with it, no problem.

but this is just and necessary, and gives the same problem.

Trace

PD: I uninstall the mouse driver.Thanks a lot!

this time the NetCoffee.exe causes the issue which is also very old (coded with Visual Basic 6). But agaon without Debug-files I can't see anything useful.

I'm having a bit of an issue. After running the suggested programs in the OP, and if I am reading this correctly, it seems that "intelppm.sys" is my annoyance?

no, idle can be ignored. this is the CPU driver which sends a halt signal to the CPU to reduce cpu power consumption.

if you're unsure, upload your trace so that I can look at it.

Apologies.

I may not actually be certain of my issue. For some reason my CPU usage has increased past the norm in the last two days. Any little task I do it seems to raise in 30-40 percent while browsing and near 70 when streaming videos from sites like Youtube. Normally the usage would not get near as high (except for when I'm rendering video). When I did the steps outlined on the first page I immediately jumped the gun and assumed the idle processes were to blame. Unfortunately I am now back at square one.

make a trace when you have the 70% CPU usage again and sahr the new trace. I look at it.

Andre this tutorial is very much appreciated.

I sent you a dropboxlink to my rared .etl file via the forum PM system due to privacy/security concerns. Please check your inbox and return with some advice.

My problem: CPU goes to 100% when downloading any file. Copying to/from USB is no prob.

As you can see avp.exe and chrome are both taking a large chunk of cpu. avp is kasperski internet security, but problem appears with eset smart security as well and even with antivirus/firewall completely disabled, and completely uninstalled. ntdll.dll seems to be the culprit in both applications causing high cpu.

Have done all the obvious stuff and more, latest drivers, malware, safe mode with networking, tested with ubuntu.

the AMD V140 Processor seems to be the bootleneck. It is a cheap Single Core CPU.

Chrome internally has a message loop and this causes fr a example 9/13% cpu usage (chrome.dll!MessageLoop::DeferOrRunPendingTask, 12.37, chrome.dll!base::MessagePumpWin::Run, 9.37)).

Kaskerspy scans the HTTP traffic (HTTPProtocoller.PPL, anti-phishing http filter.dll) while surfing. So try to disable this scanning. Maybe this helps a bit, but the CPU is simply to slow for todays software. You should use at least a Dual Core cpu with 2GHz. Look if it is possible to upgrade the CPU.

Thank you for your wonderful efforts.

Ya the laptop is crap, impulse shopping be damned. But surely the hardware/processor of my laptop should be able to handle refreshing a webpage without cpu spiking to 100% for a fraction of a second. That's what is happening right now, and worse when dl larger files. The machine is only 14 months old, dunno when it was released though. Thing is during a period of 2-3 weeks the prob went away, so while yes the processor suck it shouldn't manifest in the cpu probs I have right now.

did you use the same Kaspersky version during the test? For me Kaspersky was always a performance hog that's why I never used it. So try to disable the anti-phishing scanning and stop all background tools which are not needed.

Ye, it was the same version, if by that you mean program version. I'll uninstall Kaspersky, and try eset antivirus only. iirc the period during which I had no prob was when I had only eset antivirus and windows firewall. Yea windows firewall sucks but it's worth it if it solves the issue.

I use the same combination (NOD32 + Windows Firewall) and this is ok.

Hehe guess I shouldn't bash windows products on this board :blushing: I've decided, after tens of hours of trying to solve this problem, to try with a fresh install of windows 7. I'm going to do it virtually this time tough hrough WMvare because I can't be arsed to dual boot. What do you think about that? Could there be that the circumstances that matters isn't identical so I can't isolate the problem through virtualization? Ie I take the time to setup WMvare and install windows 7 vritualized and problem is gone. Then when I do a fresh install problem is there again. Never done virtualization or WMvare before.

Thing is before I send laptop in to service center I want to be 100% sure this isn't a software issue. Otherwise they might charge me. So will I be 100% sure with virtualization or do i have to boot from a fresh windows 7 to be sure and see if issue persists?

No, I also don't like WIndows 8 with Metro and tell this here. But Firewall is fine.

But running a VM with your slow system is no good idea. remove Kaspersky and use NOD32.

I have uploaded the trace file to http://www.mediafire...7svn9bx6m88c88e

Another thing I have noticed is tht if i stop the diagnostic policy service, the cpu usage goes down from 100% to 50%.


thnx so much for your help.
