problem, all help appreciated!!

Yesterday my pc was working fine, but i booted up this morning and after a few seconds of logging into my account, the screen went all funny. Could it be because I just updated my nvidia 6800 to forceware 175? My OS is Xp professional 32-bit. How can I fix the problem?

I don't think so, because when it gets to the welcome screen, I can log in and my account is fine for a few seconds, but thank you very much, I'll give it a try...

... it seems to be ok now, thank you J.D, but now I am stuck at res of 640x480, and it's not the best of res's to be at, and my colour quality is 4-bit, is there any way now to get back to my old res of 1280x1024?

well, I have just uninstalled 175 drivers, still can only use 640x480, I tried to dload some drivers from nvidia's site (169.21, my previous drivers) but explorer and firefox both keep crashing

Having uninstalled drivers and restarted XP, the system appears to be fine, I will use the trustworthy 169.21 drivers, thank you very much for your help
