FX 5700 crashing

[Bad^Hat]

I'm experiencing problems with this card, and it looks like it's a driver issue. When I installed the latest Nvidia display drivers (61.77), it told me the software for the 5700 wasn't Windows Logo certified or something, so I quit out and did a quick Googling, and came up with a few forum posts that said to ignore it. So I did, and now it's crashing (freezing really) two games, Halo a few times, and just now Battlefront. When I rebooted from BF and logged back in there was an error saying the reboot was most likely caused by my display driver. Is there anything I can do about this?

Well, I suppose you could roll back to the previous drivers no?
