I have a GeForce 7900 and a GeForce 8400

I just reinstalled windows xp. It booted up just fine with the windows graphics drivers. I installed the nvidia drivers and when it boots up the screen doesn't display anything. It makes all of the sounds of booting up and logging in, but no display.

I booted into safe mode, that worked.
I uninstalled the drivers and rebooted. It booted up just fine like it did when I had just installed

I redownloaded and reinstalled the drivers. Same problem.

Everything else is working fine. I need the nvidia drivers for things like games and dual monitors.

The drivers seem to install correctly. I'm in safe mode right now and the cards are being detected

What should I do?

OMG MY FUCKING COMPUTER DOES THE SAME THING. I have a nvidia 9800 gt. what a peice of shite. How in the FUCK do I fix this? I am on safe mode right now wtf.

Possible case; nvidia doesn't detect the right settings for your monitor. If you have a spare computer, you could try the following.

Reboot into safe mode and remove the nvidia drivers. Reboot into normal mode and install any VNC server, like RealVNC's free edition. Install the nvidia drivers again and reboot to the black screen. Then install the VNC client on the other pc, and log into your own. If you see the normal desktop, just go to the nvidia control page and look up your monitor. Check if the main monitor is the right one and where needed, adjust the resolution.

Remember to remove the VNC server as most VNC's don't really have a reputation of being safe.

Maybe the resolution is out of range for your monitor?

to keep things short and sweet you have a faulty graphics card.
had a couple like this, one exactly like yours as soon as the card went under any load what so ever it blackscreened (i.e. as soon as the drivers loaded) and another that blackscreened when using 3d acceleration (i.e. game enviroment)
send it back under warantee.

I mean i doubt it is the faulty graphics card because i had the same thing on the same graphics card before and it worked fine, it was only when i tried to reinstall the same drivers i had before that it went to shit.

I might try the vnc thing though, as it happens i have a laptop right next to me with vnc already installed on both computers :0 thanks for the help
