Message from device manager: Windows encountered a problem installing the driver software for your device Windows found driver software for your device but encountered an error while attempting to install it. NVIDIA GeForce GT 750M Message from NVIDIA Installer: NVIDIA Installer failed. Graphics Driver 340.52 Failed. Description: After my pc freezed all of sudden while running emulators (i also had an auto windows update few hours earlier), windows refuse to detect my GPU and NVIDIA installer keep failing... Luckily i have two GPU but i cannot use the NVIDIA one due to this issue. ASUS Tech Support Little talk with ASUS Support and they asked if i had a critical windows update recently. They asked me to try a system restore, which seem to solve the issue (i could see the GPU card but only for some minutes). Now after that i being asked to format the pc. This is why i write this thread. I hope someone can come up with a solution. Thanks in advance!
