I just got a new system as a wedding present and am having trouble getting the graphics card to work. I am fairly certain the card is working fine as we tested it in another system that uses XP and it works.
Until my card came, my friend was loaning me a 8800 which worked fine. Once mine came in I have had problems.
I have an MSI 9800 GT and am running Vista x64 Home Premium.
Only the standard vga driver seems to be stable.
I have installed every NVIDIA forceware version that lists the 9800 GT and none of them work. After installing any of them but the newest beta driver package the system shows the little windows loading bar then has a black screen. With the newest beta drivers windows will come up, but has frequent freezes. When I say freeze I mean the fan and power continue as normal, but the screen stops frozen in a frame and the mouse and keyboard do not respond.
It freezes every time I try to run a 3d game, run dxdiag, or any 3d system test program. It also freezes frequently in Internet explorer, but not Chrome. Often it freezes at a screensaver as well.
I don't think this is a power issue because I have a 700 W power supply which ran the 8800 just fine, and I would think I could get the other drivers to boot windows at least if it was a power issue.
