Re: blank monitor
Damn. 'o.O That's some weird shizz. Mr. Technician had some interesting ideas which I ordinarily would've suggested, but the fact that opening a program causes the monitor to work is incredibly strange.
First thoughts that come to mind? Well, my mind jumped to a dodgy refresh rate or resolution setting, but that seemed to dwindle once I read the E-Mail program bit.
My friend, the best thing you can do right now is to try an alternative monitor; it's basic diagnostics, so it's worth doing.
Let us know what happens with a different monitor. Generally speaking, if another monitor works fine, then either it is the pins, the monitor, or it's drivers/software/settings somehow interfering with the monitor, and if that's the case, I'm afraid it could be so many things, so it's a case of process of elimination.
Worry about trying a different monitor first.
If we don't speak again, then good luck.
