so here's the deal: i'm using windows XP professional sp3 and it's worked fine. Last saturday we had a celebration, kinda like christmas, and i got a wireless dekstop set from microsoft, worked like a charm. But then the program from my old keyboard (which was a 'multimedia' one, with lots of buttons to activate programs) was acting up, so i decided to delete it. When i pressed uninstall, it hangs for about then minutes, then it goes to about half way and then just hangs forever. Since then, when i try to shut down my computer, i go to start and select shut down. I hit the red shutdown button, but it restarts the computer for some reason. When i try to log out my account, i get a blue screen with a change log for about 5 seconds, then it restarts the computer. when i try to hit restart, it does nothing and goes back to start. anybody formiliar with this? thanks in advance.
