T6nn_k Posted May 8, 2017 Share Posted May 8, 2017 My friend had similar issue when he used Afterburner to overclock. Turned out that it had messed up EDID. Look into that. Quote Link to comment Share on other sites More sharing options...
optikz Posted May 8, 2017 Author Share Posted May 8, 2017 is this a registry thing? does anyone know if I can just reset the EDID's? it looks really complicated.......... Quote Link to comment Share on other sites More sharing options...
T6nn_k Posted May 9, 2017 Share Posted May 9, 2017 Just asked my friend about it and he ended up taking it into repairs and had to get a new display. Quote Link to comment Share on other sites More sharing options...
optikz Posted May 10, 2017 Author Share Posted May 10, 2017 Thanks for responding. Do you know if he tried any of the software fixes? Quote Link to comment Share on other sites More sharing options...
T6nn_k Posted May 10, 2017 Share Posted May 10, 2017 He did try but it was too difficult. Quote Link to comment Share on other sites More sharing options...
optikz Posted May 13, 2017 Author Share Posted May 13, 2017 holy crap i finally figured it out....thanks so much for pointing me in the right direction i would have never found that this was what happened. it took me a while to figure out that that everything was really on the img file from t456 . I kept looking for the instructions through windows. All i had to do was restart and boot from it and all instructions were there. Quote Link to comment Share on other sites More sharing options...
T6nn_k Posted May 13, 2017 Share Posted May 13, 2017 So what was wrong and how exactly you solved it? Quote Link to comment Share on other sites More sharing options...
optikz Posted May 13, 2017 Author Share Posted May 13, 2017 (edited) supposedly it was using precision x and something to do with windows 10 readiness updates and or nvidia drivers. nobody really knows supposedly. http://forum.notebookreview.com/threads/evga-precision-x-and-windows-7-8-8-1-and-especially-10-bricking-systems.781467/page-23 Here i downloaded the linux img that is provided. i used the usb tool like is explained in that post to recover the img onto a usb stick. I was able to use an external monitor using hdmi. Restarted and booted into linux hitting f7 for boot options to boot from the usb. started linux without installation which was the first option. then all files and instructions, including pictures are on the desktop once linux is started. it was way over my head as to what i was doing but the instructions are very clear. Just restarted and the monitor was back. the only confusing thing is figuring out what monitor it was. when you start the instructions and find the edid that is corrupted it shows what lcd it was, i also used a tool called moninfo that showed an existing registry of the lcd number in windows.
