    100% cpu utilization (xp pro - sp2 currrent)

    Twice within the last two days my system has completely locked up. This happens during periods of inactivity (apparently only screensaver running).

    This morning, I was able to ctl-alt-del and get the performance screen showing 100% cpu. Apparently no interrupts were being serviced. Multiple attempts at ctl-alt-del did NOT give me the option to shut down - I had to power off to reboot.

    I suspect the United Devices screen saver as the culprit - the little blue pill that shows up in the tray had a little bar signifying that it could not reach it's server. I have since disabled the UD screen saver and taken it out of the start up list to see if that is the problem.

    I am trying to figure out if there are any foot prints hanging around to debug the problem. I seem to remember a "RUN" command that displays a history of problems recorded by xp, but I can't remember what the run command is to display the log - I just found it - evenrtvwr.msc - nothing of interest in display (only a couple of startup messages from the reboot).

    Does anyone have any ideas to try if and when the system hangs again?

    Thanks in advance

    If this is the United Devices screensaver you are referring to, I'd recommend that you remove it and not use it again. Several years ago, I allowed a research project to use my system "when it was idle" for research purposes. I had similar problems to yours and the solution was to remove the research applet and not allow them to use my machine any longer.

    I have now id'd another problem after another system hang - when I add or delete a USB device - I do not get the little message saying that xp found a new device

    After last hang, I removed all usb devices except mouse and key board and moved mouse and keyboard to front panel (from rear usb ports) usb ports

    now am running with just mouse and keyboard - added one device to port in back and did not get the xp bubble saying new device found

    Is there a simple usb port test i can run on ports in back?

    You could go into Device Manager and check the USB line item for any "yellow flags" indicating a problem with them.

    Satrt>Run and type devmgmt.msc to bring up the DM screen.

    You could try http://www.usbinfo20.com I purchased the software from the author just prior to his death. I have checked for the new editon for months before giving up in dejection. I went to the site for the URL for you and find the the new version has now been released.

    I am not at all sure what is going on - after working with every ones suggestions, spending a lot of wasted time talking with Dell's crack Indian Support Staff, going out to local bar and drinking for a couple of hours, and a good night's sleep- I got up this morning to same problem! Just prior to pulling the power plug again I accidently hit the little silver "go button" right above the big Dell logo on front of the box and my desktop appeared.

    I made a bloody mary, read the sunday comics, took out trash and thought - this looks like a laptop that went into hibernation!

    Went into the control panel for display and sure enough the box was set to go into hibernation ofter 15 minutes of inactivity. I am not at all sure how this got set, or even when it got set - I didn't even know Hibernation was an option for desktops. Something has changed and I have no idea how it got to this point.

    I have now set the display so it never goes into hibernation and will see wht happens this afternoon when I watch the ball games.

    Again - thanks for tips - I saved the url for the software that tests usb ports - that looks really good - just hope I don't need it in the future, but if I do, I have it.

    Several funny things happened during this excusion into madness - at one point I disconnected everything and readded devices one at a time - back of the work station is a maze of wires, power strips, dropped pencils, lots of dust, you all know that story - I now have one power adapter with a tiny round plug (black inner circle - which I am told denotes some unique voltage configuration) that does not have a home. Every thing appears to work and I have no idea where it goes - do not have inclination or patience to attack the maze again - some day something won't work and I will have the answer.
