first i installed the 40.72 drivers for my GF4 ti4600 but i found the preformance to be terrible so i switched back to 29.42's. i then overclocked my gpu alittle, not too much (and i have previously gone higher so its not the problem) not i find that when i press ALT to get up the menu screen the right hand side of the screen blurs, i have included a screen, please help me if you can, thank you,Lee :-zhelp

Haven't seen this problem, but did you uninstall the previous drivers before installing the new ones? Make sure you do this. There is also a tool on guru3d (I think) called detonator destroyer which will help you make sure you completely uninstall the previous driver. If you don't, wierd things seem to happen.

If you are using Win98/ME then go to http://www.guru3d.com/ , read the instructions for properly cleaning out old driver bits and pieces, download detonator destroyer, and follow the instructions. Reinstall the drivers after you have completely uninstalled the problem files and registry entries.

i didnt uninstalled the previous ones so ill try that detanator destroyer , thanks
