Windows task manager does not open. I press ctrl+alt+del and it comes up for a millisecond and then goes away.
That right there tells me that you are infected.
Since you seem comfortable with reinstalling, etc, you should do just that. But before you do, download the latest ZoneAlarm (or whatever software firewall you like) and the latest AVG (or, whatever scanner you like).
When installing windows, keep your computer unplugged from the internet. When Windows installation is done, install your firewall and scanner. Then, you can plug your computer in and then download windows updates, etc.
Once the above it done, you can go ahead and install you games, drivers, and whatnot.
