Windows 10: Secondary monitor suddenly not recognized

Hi there,

My setup:

Intel i7-3770 @ 3.40 GHz

EVGA Nvidia GeForce GTX 1060 6GB

Win 10 pro 64 bit

My graphics card has the following outputs: 3x Display port, 1x DVI, 1x HDMI


Until now i had my main 4k monitor connected via display port and a secondary monitor FullHD connected via DVI. It was working fine for over a year. Two days ago during gaming my secondary monitor suddenly shut off. Since then it isnt recognized anymore.


Troubleshooting until now:

• any other monitors i plug in via hdmi or dvi arent recognized in windows device manager or display settings or nvidia system control i dont have other display port monitors available
• also the manual device recognition in display settings and nvidia system control doesnt find anything same with searching for new hardware in win device manager
• when starting the pc with only the DVI plugged in, BIOS and windows loading screen is displayed via DVI, as soon as the login screen would come up, DVI screen shuts down and nothing is displayed when plugging in dp at this point, win login screen is displayed there
• cables are working fine hdmi cable works with other pc, dvi screen displays bios when no other screen is plugged in
• i selected dvi as source on the secondary monitor
• when plugging into the pc the secondary monitor it lights up and tells me "no signal available"
• everything behaves the same regardless of which of my three display ports i am using
• i rolled back to different nvidia drivers and clean installed the newest driver, nothing changed anything
• i installed all available windows 10 updates and drivers
• i reset windows
• i disconnected power from all screens and waited vor 30 mins
• i deinstalled the monitor and graphics card in device manager
• i removed, cleaned and reinstalled the graphics card from my motherboard
• i tried to connect the secondary monitor either via DVI or HDMI, same behavior in both situations
• i tried to connect another monitor either via DVI or HDMI, didnt work either

i dont know what else to try... thanks in advance for your help.

:)
