Can't Change Screen Resolution Windows 8

Ok, so the video card on this computer would just cut out from time to time, and i'd to have re-set the cable for it to work. I figured theres a loose connection, so i got another video card to replace it with, since this is a work computer.So after installing the new (actually its a used video card, ASUS v7700 TIvx, but still definitely works) video card, the computer starts up at the correct resolution, 800x600. It looks fine, but when you drag anything or scroll on a web page, the video lags. So i found the correct drivers and installed them, and rebooted.The computer reboots in 640x480 at 4-bit color quality. When i change the resolution to 800x600 at 32-bit color quality, it just defaults back to 640x480 at 4-bit. I found that i can change the resolution to 800x600 at 4-bit, but when i try 16-bit or 32-bit quality, it just go right back to 640x480 at 4-bit.i thought maybe it was the video card, and tried to install the old one again (its a geforce 2 mx card).
So i re-install it and install the correct drivers, and still the same exact thing happens, (prior to any of this, the geforce 2 mx card worked fine at 800x600 at 32-bit) i can't get it to correctly change to 800x600 at 32bit, it just keeps defaulting back to 640x480 at 4-bit.Like i said this is a work computer, so i need to fix this ASAP. Does anyone have any ideas for me to try? It appears that putting any other kind of video card won't do the trick, because it won't work with these 2 working cards, so i think it might be something with windows.any ideas?
