Ive been having the same problems, 296 even gave me a blue screen error. I am using the 64 bit drivers. 296 worked fine for about 2 weeks for me too, until yesterday. Then it got to the point i could use it, until the blue screen. I finally got 301 up, and it crashed to (just the driver and only once). Also I have a gtx 460m and according to a desktop gadget its been running super hot lately, like 80-93 degrees celsius, within 10 minutes of any game(portal 2, minecraft, even a gamecube emulator),and just dual monitoring with netflix takes me up to 80 with out anything else going on my computer . And I used to be able to run skyrim for hours and never go above 80 degrees. Would this be related? Or would it be a hardware issue potentially?
