i should've addressed this a lot earlier, but i have problems with installing drivers for my 2 EVGA GTS 450 cards. problem is, when i go to uninstall the old drivers and restart, i can't see anything but a black screen. prior to this nothing like this has ever happend, it restarted fine and just defaulted to my mobo. even when i plug straight into my motherboard i can't see anything. i have to physically remove both cards, put 1 back in, and then plug into it and install the cards separately. went into bios and didn't see anything funny or turned off. but im assuming i'm missing something. i need to update my drivers, its been a few months. i got so fed up with this process that i just stopped updating all together!
