I posted this earlier in the WIndows OS subforum. They directed me here. I have attached the logs you requested. Sometimes (randomly approximately 6 out of 10 times) when my computer starts up, none of the programs work. I can only open folders, but no files or programs. Even the task manager doesn't show up with Ctrl+Alt+Delete. Even tried typing 'taskmgr' in Start > Run. But got nothing. AND the computer doesn't even shut down. It just gets stuck in the Shutting Down screen. When I try to open files or run programs or shut down, nothing happens. Nothing at all. The only thing I can do it turn the power off and on again and hope it works. At first I thought it happens because of not shutting down properly (power cuts). But then I noticed it happens even when I shut down properly. Any suggestions? Thanks -Farhang PS: I don't want to act like a patient diagnosing himself, but I think my processes don't start up properly. Because you know the 'Windows Updates' icon that appears in the system tray on start up? It doesn't show up sometimes. And I noticed that the programs work properly when 'Windows Updates' icon shows up. When it doesn't appear on start up, thats when the programs don't work. Also I don't hear the Windows startup sound when the problem occours. Don't know if that will help, but just thought you might want to know. I have Windows XP installed, Pentium 4, 3.06GHz, 2GB RAM.
