MagicAndre1981 Posted May 22, 2011 Author Share Posted May 22, 2011 I have never seen this. Start a new topic in the Windows 7 forums and ask why so many items show up on your Windows. Link to comment Share on other sites More sharing options...
Dragonmaninferno Posted June 22, 2011 Share Posted June 22, 2011 Hello,For the past month my CPU has been going from 0%-40% sometimes even to 100%. I checked the resource monitor and saw that NT Kernel and System is responsible but I don't know what program or application is causing the problem. I performed a trace and I have the result up on mediafire. I'm using Windows 7 x64. Can you help? http://www.mediafire.com/?juwv0msgpwaguuk Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted June 22, 2011 Author Share Posted June 22, 2011 Hi,as you can see in the picture the iastor.sys causes 16% of the CPU usage.This driver belongs to the Intel storage driver. You use version 10.1.2.1004. Is this the latest version? If not, update the driver. If this is the latest driver, use the version before this driver. If the issue still occurs, check your Hitachi HDD for errors (run chkdsk C: /r /f) and run a diagnostic tool from Hitachi.André Link to comment Share on other sites More sharing options...
Dragonmaninferno Posted June 22, 2011 Share Posted June 22, 2011 Ok I'm not too good with computers but I went to Device Manager and went under Disk Drives and found Hitachi HT followed by some letters and numbers. Is this the one I have to uninstall? I checked for updates but it said everything was good. Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted June 22, 2011 Author Share Posted June 22, 2011 no, Hitachi HTS547575A9E384 is your hard drive. You must update the Intel Storage driver. Go to the homepage of your laptop creator, download the latest drivers and install them. Link to comment Share on other sites More sharing options...
Dragonmaninferno Posted June 22, 2011 Share Posted June 22, 2011 Ok I downloaded and installed the update. If the problem happens again I'll do what you suggested in your other post. Thank you for helping André Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted June 22, 2011 Author Share Posted June 22, 2011 You're welcome. Post again if the issue is back. Link to comment Share on other sites More sharing options...
Dragonmaninferno Posted June 22, 2011 Share Posted June 22, 2011 (edited) Ok it's happening again. How Do I delete the driver? I tried looking for the previous driver on the HP website but I can't find it. Do I have to keep searching or is there somewhere else I can find it?EDIT: Nevermind I found out how to uninstall and I found the previous version. Once again thanks for your help André.

Jaroin Posted July 5, 2011 Share Posted July 5, 2011 Hi. I am actually writing on behalf of someone else. They have Vista 32 bit. Is this software for Vista too, or just Windows 7? Thank you Link to comment Share on other sites More sharing options...

laptoptraveler Posted July 25, 2011 Share Posted July 25, 2011 Hi - I've been searching for a while trying to solve the same issue and your forum seems to be the most proficient and your response prompt.Issue: - Laptop CPU 100% typically when viewing videos or flash, but I cannot always confirm this is the cause. Typically though while in a browser.- Dell Laptop (detail below) recently upgraded to Win 7 64 - Same issue happened on Vista and I thought the upgrade would take care of it- Disabled Windows Media Player Network Sharing Service and didn't seem to work- Unplugged monitor (Hannspree HDMI) because I thought it was a driver issue, didn't have a long-term effect. Laptop: Dell StudioIntel Core 2 Duo CPU T6500 @ 2.1 GhzRAM 3 GB DDR3Windows 7 Home Premium SP 1I have downloaded the SDK and installed but the xperf command shows as invalid. I have read the post in Nov. 2010 with this " PATH environment variable and check if the path to the WPT was added". How do you check this variable/path? I have changed the registry key as you instructed for 64 bit Win 7.If I can run your commands I will post the issue here for your evaluation if I cannot figure it out. Thank you in advance. - t Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted July 26, 2011 Author Share Posted July 26, 2011 have you installed the wpt_x64.msi from the folder C:\Program Files\Microsoft SDKs\Windows\v7.0\bin? Link to comment Share on other sites More sharing options...
laptoptraveler Posted July 27, 2011 Share Posted July 27, 2011 That worked. Thx.Here's my test: - Open Chrome Browser- Go to CNN.com and play a video and waited about 1 minute for CPU to hit 100%- Captured a .etl file for two instances. Instance 1 = Playing video in browser then pausingInstance 2 = Closing Chrome tab for video.etl files are large so I have only attached screen shots of these. Once I finish this post I will zip and post the smaller file (55 MB) if you wish to see it. I stopped my video test approx. 25 mins ago and the CPU is still at 100% or very close to it, so it is very slow zipping and FTPing a file. Attached are four files: Capture_1a = Summary table from Instance #1 Capture_1b = Summary table with Chrome.exe expandedCapture_2a = Summary table from instance #2Capture_2b = ExpandedYou'll notice Task manager is open as well and I did this to monitor CPU but Task Manager also locked up and required reboot twice while getting the .etl files. I'll post a zip location of the smaller etl if you want to view this. Thank you. Link to comment Share on other sites More sharing options...
laptoptraveler Posted July 27, 2011 Share Posted July 27, 2011 (edited) Here's the second .etl file: http://www.icita.net/etl/latency2.zip (10mb zipped) Edited July 27, 2011 by laptoptraveler Link to comment Share on other sites More sharing options...
