First off, thanks for taking a look at this. Ok so i have a late 2008 unibody macbook pro 15" (got it right after it came out). 2.8 GHz, 4GB, using the 9600m gt. I ran bootcamp on it and installed windows vista 64 bit. haven't used the windows side for anything other than random gaming, do all my web browsing and all that on the OSX side. So here's the problem: I need to update my Drivers for the 9600m gt graphics card. I haven't updated the driver since i got it, so it is waaayyy behind. So i went to Nvidea's site, found the newest mobile driver (version 260.99 for the 9600m gt among many many other cards), downloaded, and installed with the "clean install" option. after installing and restarting at the prompt, my resolution has been reset to 600x800 (down from 1440x900). I type in my password at the login screen, and.... BLACK SCREEN. Nothing but blankness, desktop doesn't load, nothing, just blackness. clicking, keypresses, etc, does nothing. it's not asleep and the display's not off, it's just a black screen. i've found that if i do a ctrl+alt+delete it will suddenly bring back the UI (at 600x800), it then has lingering drag-window effects if i move windows around, and i get an immediate error stating that "windows manager has stopped functioning". I can go into control panels and all that, change my res back to 1440x900, etc, but now when i try to run any application, be it something like xfire, or a full screen game, they error out almost immediately, not responding, and closing unexpectedly. so basically the machine is unuseable. What i've tried so far: my first instinct was to roll back. I did so, rolling back to the previous driver, and everything ran fine once again. Since then i've tried re-downloading and reinstalling the 260.99 driver a few times in different ways (like leaving out the things that aren't just the basic driver, i.e. physx, 3d display crap) and every time, it results in the same black screen followed by constant application crashes. HELP, what's going on? Any help would be much appreciated. I really need to upgrade my drivers, It's gotten to the point where even though I'm well above spec for games and whatnot I get terrible framerates and get notifications stating that I should update my driver. Help.
