Im not really sure what is wrong with it. I power up and everything shows up fine. Then when it gets to the login screen the monitor turns off and says it has no signal. The 2nd vga still has signal though. So when i type in my password (even though i cant see the 1st screen) and login the 2nd screen will come up but i cant do anything on it since everything i double click on opens in the first monitor. Everything was working fine before i powered down, then i power the computer back up and this happens. Any idea what the problem might be? Or what i can do to make the 2nd monitor my primary monitor?
