Ok, so I just built my new system a couple weeks ago. With it I bought a PCI-express Nvidia 6600 128mb card. It has been working fine until tonite.
I was doing nothing but playing games and I got booted from 2 different games... one was a bug in the game (it even brought up a bug reporting webpage after showing me the error) and the other game kicked me out for an unknown reason.
Either way, I rebooted just to kind of clear things out. When the system came back up, I had lost all video quality. The resolution was 800x600 and 4-bit. 4-BIT!
So I figured it blew out my drivers so I reinstalled them. Nothing. I rebooted again just in case it was a fluke, nothing.
3 things I did notice are a couple of errors that popped up.
1) nvuClockInit failed (I assume this has to do with the utility that comes with the video card or the actual card itself.)
2) "could not read memory at address 0x00000000" or something like that... that was an error from the utility for sure.
3) Windows couldn't find file (null). This was the strangest of all.
I have since rebooted in safe mode where the video card did appear to work like it should at the normal resolution/color. WEIRD.
However, going back to windows after this did not appear to fix the problem.
I am now running off of my motherboard VGA and when I rebooted the last time I got a message saying a registry error was repaired.
So if you're still reading... does anyone else think my video card is hosed? I think I'm calling Gigabyte tomorrow to find out for sure. (they're the maker of the card).
