PC locks up after coming out of standby

Geoffo_M

I have Windows XP - no malware, no virus - yet 50% of the times I bring my PC out of standby it will completely lockup, usually when I use the internet. I then have to reboot. I only have java and shockwave flash in my add-ins. Has anyone else experienced this?

Right-click My Computer - Manage.

Look in Device Manager for red and yellow symbols, particularly for USB devices.

Look in Event Viewer for red errors or yellow warnings.

What's the make of model of this computer?

Thank you for trying to help chippy.

There were no red or yellow symbols in the Device Manager. In the Event Viewer, there are 2 yellow symbols under Applications with the following messages:

User: COMPO/Owner
Windows cannot unload your classes registry file - it is still in use by other applications or services. This file will be unloaded when it is no longer in use.

User: NT AUTHORITY/SYSTEM
Windows saved user Owner registry while an application or service was still using the registry during log-off. The memory used by the users registry has not been freed. The registry will be unloaded when it is no longer in use.

The PC is a Dell Optiplex GX260. It is the computer I was using at work before our office closed down. Originally on this PC was Windows NT, and in the bottom right hand corner, there is always a monitor with a red X where I think it is trying to load a network card. When I was given this PC, I had it reformatted and XP installed. I'm wondering if this network card is something to do with my lockup problem - although there were no errors showing under device manager. What do you think?

Usually standby issues are caused by dodgy drivers or services which aren't working properly with the XP power features.

If you are patient, you could try to update all your drivers etc. to latest version and/or remove anything which is not needed. Keep rebooting after each time and see if that solves your problem.

For me, i have no patience so I use Hibernate instead. Takes slightly longer to boot/shutdown but works virtually all the time.

Thanks hobo I hadn't heard of hibernate - I'll try it and see it that works

If the time of those 2 warnings coincides with the time that you put the computer into Standby or resumed from it, they could be the reason for it locking up. For the first one, see Troubleshooting profile unload issues. The second warning is also related to this. Double-click each line and then click the 'For more information' link if there is one.

I doubt it. The red X is usually because an Ethernet cable isn't plugged in to the network card, however Windows sometimes displays the red X even when a cable is plugged in. Is the computer connected by Ethernet cable? If not, you can hide this icon, or hide it anyway.

Both the warnings are timed at the same time as the lockup. I shall follow your link and investigate further for a 'For more information' link

It used to have an ethernet cable when it was back in the office. It has no cable now. I think during startup it recognises the network card, and then can't find the software to run it and so marks it with a red X "unplugged cable". Logically, I suppose this shouldn't cause a lockup

Well I've read the troubleshooting link and Miscrosoft recommend a download 'UPHClean" (User Profile Hive) which unloads user profiles from the registry. I have downloaded and installed this but it has made no difference and the problem persists. I have also changed my PC to 'hibernate' and that makes no difference.

There appears to be no answer

After installing UPHClean, did you look in the Event Viewer Application log for events logged by UPHClean? These might show which process was accessing the registry for further investigation. As described in the readme, you also might need to set additional registry keys to tell UPHClean to log additional information.
