Awesome giveaway! Good luck everyone!

Thanks for reply! I've already tried every type of installation: clean and not clean, with 3d stuff and with only graphics driver. But it doesn't help. 310.90 driver doesn't work too. The only working drivers are from lenovo's dvd.

Hello guys, this is my first post here! Im using laptop Lenovo Y550 and im having problems with drivers. I used gpu drivers from lenovos dvd(ver. 186.47) with no problems but i wanted to update them. I downloaded latest drivers from nvidia.com (tried both 313.96 beta and 314.07 whql), deleted my old drivers and installed new. But then Ive started to have troubles. My resolution dropped from default 1366x768 to 1280x720 and I cant change it, nvidia control panel is not available, in device manager display adapter have an error. Can someone help me? I really want to keep my driver up to date. screenshots: Before: http://imgur.com/a/nlOJJ After: http://imgur.com/a/BNl9z Thanks in advance and sorry for my bad English :)
