i installed a program last night i used on xp all the time called shutdown after. i used it for the first time on my vista computer. i woke up to find it was still on even though i gave it an hour(downloads were going) the monitor did nothing so i held the power button. now when i turned it on it looked ok so i picked admin. when i logged in it gave me an entirely black screen except for internet explorer but i used mozilla. what should i do cause im begining to freakout.
