Why are people so scared of "beta" drivers? ffs they are typically the EXACT SAME drivers as what is sent to MS to get WHQL. Especially under water, not like your cards fan can stop working.
Actually, I had this happen with 280.26. Not even Safe Mode worked.... Removed my SSD and put in an old SSD review sample, installed a clean Windows 7 install, installed the 280.26 drivers.... boom. Same exact problem, no display (would have sound) or I had a display, but the system would lock shortly after reaching desktop. Safe Mode wouldn't load at all.
I've been meaning to test this a bit more, but given it should never have broken Safe Mode to begin with, I'm not even sure what to think anymore. Windows Safe Mode loads a generic VGA driver, so it shouldn't have ever happened... I ripped out the NVIDIA drivers and burned them to a cinder, then reinstalled 266.58.... boom, system was working again like nothing ever happened.
Of course, 280.26 were WHQL, so I guess it doesn't apply to beta drivers.
I've run plenty of beta drivers, but I've gotten to the point where once I find a good driver I don't upgrade for awhile. Used 266.58, then after trying 270 I noticed F@H performance dropped by ~15% and game performance dropped 5-10% for my games, so I've just been using 266.58 since Feb.
