did exactly as you said, but still mid instal the screen just turns off

yeah I did that, tried it again just to be sure, and got the same result :/

ok did that , but got blackscreen while installing driver , rebooted a bit later and still got an blackscreen as soon as windows finished booting :/ i went a bit thru the post and shall i repeat the progress with remounting the card?

Ok used DDU to remove the driver, extracted the new one and deleted Display.NView Display.Update and Display.Optimus, but could´nt find NVWMI , copy/pasted nvdmi and startet setup , but failed to install :/

Thanks for the quick answer, caused two new ones, the first with the posts , just five posts , excluding spamming of course , or the membership what i prefer atm , because im not that into forums, mainly because im not that confident in writing english. and the second one , i just have to repeat the progress with the driver you are refering to and remove the other one i installed?

Hey J95, I hope you can help me out, I upgraded my m17x r3 (win8.1) with a 680m and modded the 344.75 driver, disabled the driver signing via cmd and installed the driver ( was asked if I want to install it, pressed yes) then rebooted and got a blackscreen. So I disabled the IGP and set display to PEG, and now I am here. Device manager displays my GPU as Microsoft Basic Display Adapter and the id changed.
