Guest Sturdy Posted June 12, 2008 Posted June 12, 2008 Hi all, I have 2 conditions that I have been trying to correct for several months since XP Pro was re-installed (clean). Both conditions seem to occur randomly and I think both conditions may be related. Sometimes occurrences ar minutes apart, other times days apart. 1) The entire computer freezes for about 30-60 seconds cycles, unfreezes for 1-2 minutes then freezes again. There is no visible activity. Mouse et al is dead, no DSL, etc. Usually one or more reboot corrects but this has also occurred at the Win XP splash screen. 2) Taskman CPU usage goes to about 45% for several minutes then returns to normal. Taskman shows occassional spikes but no process reflects this amout of usage. Again, no network activity. It appears something is running that does not show in taskman. I've reloaded drivers, new drivers, removed all startup apps, bios changes, etc. but no joy. Device mgr indicates all devices are working without conflict. I feel this may be networking related since these issues occur most often when I try using two apps that both access the network. I'd appreciate any ideas on how to trace or resolve the problem. TIA... Cheers, Sturdy
Guest JS Posted June 12, 2008 Posted June 12, 2008 Re: High CPU usage problem You need to find and identify the specific process or application that's runs every few minutes. For more exploratory and detailed look, download and 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 about every few minutes you should see another process (the one that's slowing down your PC) float to or near the top of the list. Then click on the process of interest that's listed in the CPU % column, once it's highlighted, right click and from the options listed select: the 'Search Online' option. 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.

Guest R. McCarty Posted June 12, 2008 Posted June 12, 2008 Re: High CPU usage problem First thing I'd recommend is to check both your System and Application Event logs. Check for Red Icons that denote errors. Freezing can be a hardware related issue with IRQ mapping. It can also be due to USB loading. You would want to check your NIC settings and make sure the operating mode is "Auto-Detect" and that any Offload capabilities are enabled. The problem may also be a background service that is halting or trying to perform some automated process ( Update or Scan ).

I'll give process explorer a try. This is what I was trying to do with taskman. Unfortunately, when total freeze occurs, everything is locked and I can't access any app so I'll need to wait for a 'partial freeze'. It may take several days.

Guest JS Posted June 12, 2008 Posted June 12, 2008 Re: High CPU usage problem Just a reminder that you will need to have Process Explorer running prior to the freeze. So run it each time you startup the PC, experiment a little so that you are familiar with it's capabilities. This way your ready when the problem occurs.

Guest R. McCarty Posted June 12, 2008 Posted June 12, 2008 Re: High CPU usage problem IRQ sharing isn't usually an issue. On ACPI setups, you'll likely see a number of shared IRQs with several devices mapped together. BIOS control is overridden by the OS, so trying to manually map IRQs isn't likely to work. About the only IRQ control is what slot you install a PCI card into. Most motherboards only provide one or two slots that have an Independent IRQ ( not shared ). Usually it's Slot #2 & 5 as counted from the Video ( AGP/PCIe ) but you have to consult the MB documentation as it usually provides an IRQ slot map. USB loading relates to how much Root Hub power is consumed. The Hubs can provide up to 500mA. The controller has a fixed amount of Bandwidth and some devices can consume a good portion of that. If loading is an issue you'll usually plug in a device and it ( or other ) USB peripherals won't be detected. You can check the loading by using Device Manager, USB Category Controllers - Check the Advanced (TAB) for bandwidth usage Root Hubs - Check the Power (TAB) for mA consumption "Sturdy" <Sturdy@discussions.microsoft.com> wrote in message news:762B034B-D9DB-4679-A555-15C86591FF2A@microsoft.com... > Thanks for the response, R.

I had a 'partial freeze' last night and the log may reflect something. A total freeze doesn't produce a log entry, presumably because the log is frozen too.
Guest Gerry Posted June 12, 2008 Posted June 12, 2008 Re: High CPU usage problem Sturdy You complain of freezes but your subject is "High CPU". As you say it could be two problems but you do not seem to have not seen any evidence of high CPU usage only freezes? Could the high CPU usage be a red herring? Is this a laptop or desktop? It could be dust inside the casing. Remove the side panels and use an Air Duster. Have you checked your hard drive? Try HD Tune only gives information and does not fix any problems. Download and run it and see what it turns up. You want HD Tune (freeware) version 2.55 not HD Tune Pro (not Freeware) version 3.00. http://www.hdtune.com/ Select the Info tabs and place the cursor on the drive under Drive letter and then double click the two page icon ( copy to Clipboard ) and copy into a further message. Select the Health tab and then double click the two page icon ( copy to Clipboard ) and copy into a further message. Make sure you do a full surface scan with HD Tune. Another possibility is faulty RAM? What are your anti-virus / anti-spyware arrangements? How much RAM do you have? Try Ctrl+Alt+Delete to select Task Manager and click the Performance Tab. Under Commit Charge what is the Total, the Limit and the Peak? I would be interested in seeing a Disk Defragmenter report. Open Disk Defragmenter and click on Analyse. Select View Report and click on Save As and Save. Now find VolumeC.txt in your My Documents Folder and post a copy. Do this before running Disk Defragmenter as it is more informative. -- Hope this helps.

Guest Sturdy Posted June 12, 2008 Posted June 12, 2008 Re: High CPU usage problem Hi Gerry, thanks for the response. > You complain of freezes but your subject is "High CPU". As you say it > could be two problems but you do not seem to have not seen any evidence > of high CPU usage only freezes? Could the high CPU usage be a red > herring? > Please see my first post. I apologize for the confusion. I think high cpu usage is the root of both problems (freeze and slowdown). The first (and most often occurring) is a total lockout (freeze) where it's like somebody pulled the power but the image stays on the monitor. No input or output of any kind. The second condition is about 45% usage (slowdown) where the system slows and the mouse is jerky but IO still possible. I assume both conditions may be caused by the same errant process or condition totally or partially hogging the cycles. In the total freeze, there is no way to view anything except what is already on the screen since the entire box is frozen. Taskman freezes as does event logging. Process Explorer (recommended by JS) may do the same but may show added detail at the time of the freeze/slowdown. I'll try PE tonight but will need a freeze or slowdown to occur. In the slowdown, Taskman is still operating and shows 45% usage but there is no process visible in Taskman that shows more than 2% cpu so something else is consuming those cycles. PE may show more detail. By 'red herring' do you mean a deception or not really slowing down? I can assure you the system gets much slower. I routinely check for malware and find none. I use Symantec AV/AS/firewall (a freebie provided with my Verizon DSL account). These issues also occur when the AV or Spybot S&D is not installed. The problems doesn't seem to be any recognizable app. I don't think malware is phoning home since there is no network activity. But it could be building a file for later broadcast. > Is this a laptop or desktop? An old desktop workhorse but it is clean and cool with plenty of air movement. CPU temp is low but I don't remember exactly (I'll check tonight). > Have you checked your hard drive? Well, no. Three internal HD ( 80, 120, & 300 GB) but never a hiccup since I added the 450W PS. These issues were occurring before the 300 went in. Also a CD and DVD drive but the problems haven't occurred when the opticals were in use. > Try HD Tune only gives information and does not fix any > problems. > > Download and run it and see what it turns up.

Guest JS Posted June 12, 2008 Posted June 12, 2008 Re: High CPU usage problem A couple of tips on using Process Explorer. 1) You will notice one or more small graphs directly beneath the menu bar. The one on the left is the CPU usage graph, double click on the graph to get a larger graph. 2) If you mouse over any spike in the CPU usage graph you will see what process caused the spike. 3) Select the 'View' option in the menu bar, near the bottom of the View list is 'Update Speed' select 1 second or .5 seconds, this specifies how often Process Explorer take a sample. When the computer freezes for a long period of time, wait until you get control (unfreezes) back and then check (mouse over) the right hand end of the CPU graph, even if Process Explorer freezes you just may be able to see what caused the problem. If it's an Svchost.exe process that is taking all the CPU resource. In the 'Process' column, double click on that particular Svchost.exe process Then click on the 'Services' tab in the Window that pops up.

Guest Sturdy Posted June 13, 2008 Posted June 13, 2008 Re: High CPU usage problem Hi JS, et al TGIF...With all the ideas presented, I had a lot more than I could handle last night. It looks like troubleshooting this problem will take several days. But I really appreciate all of the help from you and the others that responded. Here is what little I learned: 1) The good: CPU temp is steady at 48/118, system temp at 37/98. Defragged C: but it was not very fragmented. As I was sleep deprived, I saved but forgot to copy the report. 3) HDTune doesn't seem to like my drives. Benchmarks look okay but Info and Health tabs are blank. Error scan (Quick) looks okay for C:. Will do full when I have time. HDTune.com is apparently down so I can't dl the manual and there is no Help file (cool app tho). 3) Process Explorer may have uncovered some unusual activity. PE seems to reveal more than you ever need to know ;-) > If it's an Svchost.exe process that is taking all the CPU resource. > In the 'Process' column, double click on that particular Svchost.exe process > Then click on the 'Services' tab in the Window that pops up. No freezes last night. I had two slowdowns that indicated svchost where cpu went to 80% for about 20 minutes each. I looked at the lower pane (a bunch of entries but didn't see anything unusual (or that I understood!). Didn't know about the above so will try that next. I need to RTFM. Strangest, I had a third instance that went to 80% for about 30 min before I reduced to about 6% by shutting down apps one at a time (no help). The strange part is that the app hogging the cycles was procexp.exe. I don't understand how that is possible. I tried to recreate but gave up and went to bed at midnight. Seems suspicious that all three instances went to about 80% for several minutes. Since there is no obvious slowdown, periods of high usage may be happening more often than I realized before PE. I don't think PE would normally go to 80% since it would be too intrusive if it consumed that much cpu. This appears to be the most likely avenue to continue troubleshooting. Could this be a hijack? Again, thanks to all for the assist. Sturdy

Guest Sturdy Posted June 27, 2008 Posted June 27, 2008 RE: High CPU usage problem Hi all, Well, it's been two weeks and not a hiccup! We must have really scared this old box! I have been monitoring everything with procexp but no freezes, slowdowns, etc. I'm sure it's waiting to get me when least expected...sigh. I just want to thank everyone for the helpful assistance. Best regards, Sturdy
