Firstly, I would recommend using DDU to uninstall your GPU drivers. Next; what type of cable are you using to connect your GPU to Mobo? I would use a DVI cable. So I would pull out the GPU, then use DDU to uninstall the driver then I would do a CMOS reset. To do this, just pull the CMOS battery out of system for 5 minutes.
Then reboot, go into BIOS and make sure that you have enabled the onboard GPU. That is the GPU on your Intel CPU. Which is the Intel HD 530 graphics. This should get your monitor showing correctly.
Then find your driver/software package for you Nvidia GPU. Turn off system, install card, boot up, go into BIOS, disable onboard GPU. enable PCIe GPU save and exit. Once up and running install your Nvidia GPU driver with DDU. Make sure you install the software side of the driver.....this is where you use the software to set the fan curve. I have a EVGA GPU and use the Precision X 1 software to set mine.
