So, the other day, my screen just went black. I rebooted, see the bios screen, see the loading bar, and then black. Windows was booting because it was making noise from the speakers. Well, I blamed vista of course and tried to install XP. This time I got to the desktop, but as soon as I installed a display driver, this would happen again. So I re-installed vista because I figured it was a hardware issue, not the OS. Same symptoms. Finally I tried using the VGA port instead, and voila, we're good, except it's VGA.
My question is, if DVI is working at the bios screen and with no display driver installed, thus low-res, but not working once I install the driver, is it more likely that my graphics card has a bad dvi port or that it's my monitor? Of course swapping to a different monitor would tell me, but this is the only DVI card I have around and only DVI capable monitor. What would be your guess?
