Processor at 100%, no obvious cause
OK, I've done what you suggested. Nothing too radical to report. These are
the 3 "Warning" events I get in the System log - nothing of interest to report in the Application or other logs: ID=20169, 15:14:17 Unable to contact a DHCP server. The Automatic Private IP Address 169.254.104.213 will be assigned to dial-in clients. Clients may be unable to access resources on the network. ID=20169, 15:14:17 Unable to contact a DHCP server. The Automatic Private IP Address 169.254.134.244 will be assigned to dial-in clients. Clients may be unable to access resources on the network. ID=20192, 15:14:23 A certificate could not be found. Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate. No L2TP calls will be accepted. As the computer is not connected to the network (and therefore not to a DHCP server) I don't find anything too surprising except that two private IP addresses are mentioned. Note I don't that this is just a boot issue...after booting up, the processor continues to run at ~80%. Thanks, Alain "R. McCarty" wrote in message ... The proper diagnostic on boot issues is Event Viewer. Services are highly interdependent. Some start only after others have completed. The way Windows is designed a Service Start can wait as long as 30 seconds. I would use EventVwr.Msc [Enter] and clear both System & App logs and reboot. Then reopen EventVwr and examine both logs for Red and Yellow icons that denote Errors and Warnings. This way you are working with a single/complete boot sequence.

The CPU graph shows the same thing. I have not attached JPG images of both, but have cpatured them showing the above. Can email if it might clarify. I don't know whats' going on here. Since no process is running at more than a few percent, the overall CPU Usage should only be a few percent, but its almost maxing the CPU.

I've tried disabling several devices in Device Manager and rebooting, and still get the same problem. Any ideas, please? Thanks, Alain |

Thanks for the updated info. If the PC is not on a network is it connected
to the Internet at all ? If not then I'd either disabled the Ethernet NIC or unbind the Protocols/Services from it. Part of your bootup issue is going to be the time lag for NIC initialization. That's why it eventually obtains the "Autoconfiguration" address starting with 169.x.x.x "Alain Dekker" wrote in message ... OK, I've done what you suggested. Nothing too radical to report.

Processor at 100%, no obvious cause
This file is part of XP itself, so in some sense the slowdown is a "feature"
of XP. I had a similar problem about a year and a half ago. The best I could do was drop the priority of the task using "process explorer", which is free from Microsoft at http://technet.microsoft.com/en-us/s.../bb896653.aspx From the main window, right-click on any process to get a menu, which includes set priority. However, some time in the last year or so, this problem fixed itself. That might have been due to installing SP-3 and/or some associate update via windows update. Searching the web for "wmiprvse.exe" also suggests that updating device drivers might help. Windows update will show some newer drivers, if they are available. But, not all drivers are available via windows update. So, check the support website of your motherboard, video card, etc. "Alain Dekker" wrote in message ... Hi, I have a PC running Windows XP, SP3.

The service Windows Management Instrumentation has the Security Center and the Windows Firewall dependent on the service. You might try changing the startup type to manual. I am not sure affect it will have. Select Start, Control Panel, Administrative Tools, Services and right click on Windows Management Instrumentation and select Properties. The StartUp type should be Automatic. Changing to Manual using the scroll bar to the right of Automatic may help. The problem with no internet connection is most applications expect to connect to the internet to update and regularly check to see what updates are available. The most obvious is Windows Automatic updates. It may be preferable to disable Automatic Updates first before making the change to Windows Management Instrumentation . Start, Control Panel, Automatic Updates. JS has suggested Process Explorer. This is my standard response for Process Explorer. Given no internet access you will need to download to another computer and transfer the programme. Download Process Explorer.

The Automatic Private IP Address 169.254.104.213 will be assigned to dial-in clients. Clients may be unable to access resources on the network. ID=20169, 15:14:17 Unable to contact a DHCP server. The Automatic Private IP Address 169.254.134.244 will be assigned to dial-in clients. Clients may be unable to access resources on the network. ID=20192, 15:14:23 A certificate could not be found. Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate. No L2TP calls will be accepted. As the computer is not connected to the network (and therefore not to a DHCP server) I don't find anything too surprising except that two private IP addresses are mentioned. Note I don't that this is just a boot issue...after booting up, the processor continues to run at ~80%. Thanks, Alain "R. McCarty" wrote in message ... The proper diagnostic on boot issues is Event Viewer. Services are highly interdependent. Some start only after others have completed. The way Windows is designed a Service Start can wait as long as 30 seconds. I would use EventVwr.Msc [Enter] and clear both System & App logs and reboot. Then reopen EventVwr and examine both logs for Red and Yellow icons that denote Errors and Warnings. This way you are working with a single/complete boot sequence. From your description it appears you have a case of incorrect Service start modes. "Alain Dekker" wrote in message ... Hi, I have a PC running Windows XP, SP3. When the computer starts, I load Task manager, and get about 2 minutes of the process: wmiprvse.exe running at 100% CPU usage. After about 2 minutes, that process goes to 0% and the only visible task with a non-zero number (apart from occasionally rising to a few percent) is: System Idle Process which is what you expect, except that "CPU Usage" at the bottom of Task Manager shows in the range of 80-90%. The CPU graph shows the same thing. I have not attached JPG images of both, but have cpatured them showing the above. Can email if it might clarify. I don't know whats' going on here. Since no process is running at more than a few percent, the overall CPU Usage should only be a few percent, but its almost maxing the CPU. I figured it must be one of the several bits of hardware I have attached (COM, Parallel ports, etc). I've tried disabling several devices in Device Manager and rebooting, and still get the same problem. Any ideas, please? Thanks, Alain |

Processor at 100%, no obvious cause
OK, tried putting WMI to Manual (I'm a software developer do I know how to
change that), no help. I do have some information from Process Explorer, though (great suggestion, thanks). The first two lines immediately tell me the problem (but not the cause): Process PID CPU Description Company Name System Idle Process 0 18.18 Interrupts n/a 80.30 Hardware Interrupts For some reason my system is spending a HUGE amount on time on "Hardware Interrupts". I've checked Device Manager and everything looks kosher. Also, this system is just one of many which are (supposed to be) identical, hardware and software-wise.

Processor at 100%, no obvious cause
Don't think its wmiprvse.exe causing the problem - I've confirmed its in the
correct location, has the correct Windows signatures and besides after 30 minutes the processor is still hanging around 80+%. I do have some information from Process Explorer, though (great suggestion, thanks). The first two lines immediately tell me the problem (but not the cause): Process PID CPU Description Company Name System Idle Process 0 18.18 Interrupts n/a 80.30 Hardware Interrupts For some reason my system is spending a HUGE amount on time on "Hardware Interrupts".

Any idea how I find out what is causing the "Hardware Interrupts"? Thanks, Alain "Bob Harris" wrote in message ... This file is part of XP itself, so in some sense the slowdown is a "feature" of XP. I had a similar problem about a year and a half ago. The best I could do was drop the priority of the task using "process explorer", which is free from Microsoft at http://technet.microsoft.com/en-us/s.../bb896653.aspx From the main window, right-click on any process to get a menu, which includes set priority. However, some time in the last year or so, this problem fixed itself. That might have been due to installing SP-3 and/or some associate update via windows update. Searching the web for "wmiprvse.exe" also suggests that updating device drivers might help. Windows update will show some newer drivers, if they are available. But, not all drivers are available via windows update. So, check the support website of your motherboard, video card, etc. "Alain Dekker" wrote in message ... Hi, I have a PC running Windows XP, SP3.
