Windows 7 64 bit issues?

Constant crashing/hanging. I keep using FIX and it changes some things but, it comes back. I'm the Admin. and I have no permission? Can't play games Adobe Player 10 isn't compatible and I can't get Adobe Player 9 to download. I changed from IE9 to a lesser version. I answered the questions under Adobe and still my game board is blinking so fast, I can't click on it. My IE9 keeps having to re set for the connection is lost. What can I do? thanks.
