Last night, I was trying to sign in onto MSN and i wasn't able to press the sign in button. I reinstalled.. and then all of a sudden internet explorer web browsers open up repeatedly untill i had to turn off the computer from the power. When I tried turning it back on and all that would load after startup was the wallpaper. I tried safe mode, and it was the same thing. I tried "load Windows as last best used configuration" or something like that and it worked. I see the desktop, I can use the computer, but I can't type/use the keyboard. Can anyone help?
