As I said before, I have only had a problem if I mess about with screen resolution. I was just wondering if you have some program like some games tend to change screen resolutions although usually return the screen to default when finished. Is there some program in your startup sequence that is causing this. Have a look at the items showing on your task bar, you may find a clue there. If they can't be prevented there from loading you should be able to do so by typing msconfig.exe in the search box that shows after pressing start. then execute it, when the dialog opens choose the startup tab then untick the items you want to prevent starting on boot up then apply and OK. This can also help speed up booting, just don't stop essential items.
