Guest trevordixon@gmail.com Posted July 6, 2007 Posted July 6, 2007 Re: High CPU Usage Oops, sorry about those previous two posts. Here's what I meant to submit: When I open Windows Task Manager and go to the processes tab, it says System Idle Process is using 100 percent CPU. That means the CPU is free, right? But when I go to the performance tab, it shows CPU usage at a constant 50-60 percent. How can I find out what process is using my CPU? By the way, I have checked the box "Show processes from all users" in the processes tab. Thanks! Trevor

Guest JS Posted July 6, 2007 Posted July 6, 2007 Re: High CPU Usage You need to find the specific process or application that's taking 50% of the CPU resources. To do this try Process Explorer: http://www.microsoft.com/technet/sysinternals/SystemInformation/ProcessExplorer.mspx Once you have Process Explorer installed and running: In the taskbar select View and check 'Show Process Tree' and 'Show Lower Pane' options. (This will provide the detailed info you need) Next click on the CPU column to sort processes by %CPU usage. Then click on the process that's using most or all the CPU %, once it's highlighted, right click and from the options listed select: Search Online This should display what out there on the web about that process. Note: some entries like Explorer and svchost may need to be expanded to show the detail, (sub processes), in this case click on the + located to the left of the entry. Still another tool is What's Running http://www.whatsrunning.net/whatsrunning/main.aspx JS <trevordixon@gmail.com> wrote in message news:1183755723.436562.181940@r34g2000hsd.googlegroups.com... > Oops, sorry about those previous two posts.

The processes at the top are using up your CPU. And it shows System Idle Process at the top with 100 percent CPU. The performance tab shows that the CPU is at 50-60 percent usage. Why the discrepancy?

You can try Process Explorer to see if it reports the same thing: http://www.microsoft.com/technet/sysinternals/ProcessesAndThreads/ProcessExplorer.mspx -- Thanks, Jon E.

Why the > discrepancy? Try looking with Process Explorer, instead. It will give much more detail than Task Manager. http://www.microsoft.com/technet/sysinternals/utilities/ProcessExplorer.mspx HTH -pk
Guest trevordixon@gmail.com Posted July 6, 2007 Posted July 6, 2007 Re: High CPU Usage Process Explorer shows that a proccess called Interrupts is using 50-60 percent CPU. The description is "Hardware Interrupts" and apparently has no owner (there's nothing under the username field). When I right clicked it and clicked debug, it shows drwtsn32 or something starting up and then the mouse and keyboard stopped responding, so I had to do a hard reboot. It's my boss's computer, and apparently the computer started slowing down when he installed the software that came with his new camera. Does anybody have any suggestions to solve this?

If there isn't a restore point just before the new software installation, then you may be in for a system restore. What does the camera maker have to say about this situation? Jim

Guest Kelly Posted July 7, 2007 Posted July 7, 2007 Re: High CPU Usage Run the Task Manager, go to View/Select Columns, and turn on the following columns: "I/O Read Bytes" and "I/O Write Bytes." This will give you details as to which process is accessing the disk. Although many processes will be accessing the disk, look for one with a high total or a fast rate of increase, especially when you hear the drive being accessed. One further suggestion regarding Task Manager stated by Ron Martell: In the Processes tab if you click twice on the column heading for any column then the list will be sorted in descending order based on the value for that column. This helps to identify which processes have the highest values for any given item. -- All the Best, Kelly (MS-MVP/DTS&XP) Taskbar Repair Tool Plus! http://www.kellys-korner-xp.com/taskbarplus!.htm <trevordixon@gmail.com> wrote in message news:1183755723.436562.181940@r34g2000hsd.googlegroups.com... > Oops, sorry about those previous two posts.
