Hello, I'm new here; I signed on to BleepingComputer specifically to look for help with this problem:
A few weeks ago, my desktop computer began running extremely slowly. I've been trying to resolve the problem myself, since then. Doing anything, such as going to Control Panel, takes minutes. I made a screen shot of my Task Manager processes, and that took 20 minutes from start to finish. Internet navigation is the same. As I can best recall, this all started about the time there was some sort of Chrome or Firefox update, and Windows showed one of those "critical error" (or something similar) descriptions of it when I went into Event Viewer. However, I think there was a Windows update around the same time. One of the first things I tried was to go back in time with a System Restore. Obviously, that didn't work. I went back further, but that didn't work either and there were no other restore points. When (painfully) navigating the Internet, after a 5-minute-or-so lockup, I would get "Warning: Unresponsive script" errors with chrome://browser/content/tabbrowser.xml:**** (**** being 4 digits, never the same). I understand that the error was more likely due to my slow computer and not the browser, but I uninstalled both my Chrome and Firefox browsers, anyway. Internet Explorer was not running on this computer so I installed it and I am using it now, although it is Version 8 and it is out of date.
The computer is a Dell Optiplex 755, with Windows 7 Enterprise, Core2 Duo CPU E8400 3.00 Ghz with 4GB RAM. I use it as a sort of base station and home office computer, in a home network with 3 other laptops. This computer has always had full Symantec antivirus protection. It does not have wifi; it connects to the Internet via an ethernet cable. The computer works fine in safe mode, and of course that is how I am using it, now.
I sure would appreciate any help I might be able to get!
