Hi. This problem is a strange one and has become quite complicated, but I will try to keep it to the important points.
I am working on a Dell that runs XP Home(SP1) and has had no problems until now. After I hooked up the pre-existing cd-rom (it was disconnected when the user installed a burner some months ago) and plugged all USB devices back in cpu, the computer started to really slow down. In fact, it became unusable.
I unplugged everything and still had the same problem. Finally, I realized Task Manager was monitoring CPU usage at 100% over fairly regular intervals. During this time, the memory allocation for the explorer.exe process grew rapidly and reached sizes of over 350 MB! XP also grows the page file size to well over 900 MB. Normally, the page file size is around 120 MB. The computer seems to run out of memory and I need to restart or shut it off. The computer has 640 MB of RAM and runs fine in Safe Mode. Also, Mcafee is installed as are some Logitech and Kodak Easyshare software.
After extensive troubleshooting (disabling services, startup and checking for spyware, etc.), I thought I had it figured out. Disabling the telephony service seemed to do the trick. But this made no sense to me and, of course, the problem came back once all USB devices were plugged back in. Removing them had no effect and I soon realized that the problem did not always occur. One or two reboots could often go by with no problem in between. Then, out of the blue, I would see CPU usage hit 100% and the page file size would climb. Disabling all services does help, but that is not really a fix. I just can't seem to pinpoint the problem as the services at fault appear to be Microsoft's and worked fine before. Has anyone else seen this before?
One thing I have been suspicious about was any program that tries to access the Internet on its own. This computer uses a Linksys wireless USB adapter and so has not been connected during most of this process. Is it possible some program or service is constantly trying to reach out to the Internet and doesn't release memory well when it is foiled? I disabled all programs in startup via MSCONFIG and I still have this problem. Thanks, in advance, for any help on this matter.
