Everything started yesterday when I went to add a 2nd monitor on my GTX285. As soon as I plugged the 2nd DVI cable into the 2nd monitor the whole system locked up. The monitor that was on displayed some weird squiggly green line pattern and the audio that was being outputted lock up as well. I removed the 2nd monitor and rebooted in the exact same configuration it was in before the 2nd monitor was added. Everything worked fine right up until Windows finished loading. After 1 second of the Windows start-up chimes it would lock up in the exact same way; the screen goes green and the sound locks up as well.

I rebooted in safe mode and started troubleshooting. When I disable or uninstall the display adapter, Windows boots fine, albeit with no graphics options. I uninstalled and reinstalled the drivers like 4 times using different methods (drivers straight fron NVidia, via Windows update, etc) but it had the same effect each time. I also removed the previously working monitor and let Windows boot with no monitors attached to it, and again, I heard it lock up on start-up via the Windows chime locking up.

So I'm pretty certain I have isolated the fault to the graphics card but I have no idea how to troubleshoot this further. Any help would be greatly appreciated.

Remove the card via Device Manager in Safe Mode then reboot.
