on boot up my computer has a mind of its own when it gets to the desk top, the arrow of my mouse will fly the opposite way i want to go, sometimes flys off the screen never to be seen again, i get properies boxes flas up on the screen in different places, the start menu then comes up, the computer then locks up the screen goes blank and a box appeares with the words input not supported in it, this box then floats around the screen, the only way i can get out of it is to turn the power off at the wall. i have run a counter spy scan on it , it did find some problems one severe called video dial up ?? but it did clean them off. it seemed ok for a while untill i turned it off and then re booted it up.
