No video output after uninstalling the gpu drivers

[__jf____]

I tried to setup a dual monitor setup by connecting one monitor into the HDMI port of the GPU and the other monitor into the display port of the GPU.

 

The monitor that was connected via display port only showed a blank screen so I though that uninstalling and reinstalling the GPU drivers might solve this issue. I used the Display Driver Uninstaller (DDU). I also disabled integrated graphics in the BIOS before that.

 

Now both screens don't display anything. Not even the American megatrends bios thingy. This is not my photo BTW.

 

Even a monitor connected into the motherboard's HDMI port doesn't display anything. I even removed the CMOS battery for five minutes and put it back in the PC to no avail.

 

PC specs:

Windows 11

I7- 8700

8 GB DDR4 RAM

Aorus Geforce GTX 1060 6GB

Z370 AORUS Ultra Gaming (rev. 1.0)

Chieftec GPA-500S8 500W PSU

ASUS VY249HE Monitor 2x

 

Edit: A quick rundown of everything I tried so far.

I unplugged both of the drives and powered on the PC. Then the computer said: Reboot and select proper boot device or insert boot media in selected boot device and press a key. Then I plugged in a USB with Xubuntu Linux on it and both of the monitors worked. Then I unplugged the USB, restarted the PC and then both of the monitors worked. Then I restarted the PC again and this time both of the monitors are blank again but now even unplugging the drives does nothing.

 

Edit 2: after a couple dozen of restarts or so one of the monitors finally works again. Now I've made backups of all of my important files in case I won't be able to boot up my PC again after shutting it down.

Install might have gone badly.  A corruption in the new file could cause that.  DDU is a hairy low level program.  It’s important that the instructions for using it be followed.  Did you?  One way to force basic video might be to simply disconnect the hard drive so the board has to default to its internal stuff.  Assuming your monitor will handle basic video signal in the first place.

You have to also unplug the machine.

This will only work if you also remove the 1060.

If it doesn't display the BIOS screen and did before, that has nothing to do with drivers in Windows. The drivers are a red herring. Something else is wrong/misconfigured.

It worked just fine before all of this.

A week ago I bought these two monitors but because I'm a moron I forgot to check if my GPU even has two HDMI ports. It only has one HDMI and three Display Ports. So I plugged one monitor into the GPU via HDMI and another one into the motherboard via HDMI. That setup worked perfectly fine.

 

Today I bought a HDMI to Display Port cable and used it to connect a monitor to the GPU that was connected to the motherboard before that.

The display then didn't show anything after that and you already know the rest.

I powered the PC down, unplugged both the SSD and the HDD and turned the computer on. Now one of the monitors works and says:

Reboot and select proper boot device or insert boot media in selected boot device and press a key.

Edit: the issue happened again after restarting my PC but this time even unplugging the drives does nothing.

Cable could be bad.  It happens.  Not very often, but it happens.

Well there you go.  If it didn’t work then did when you pulled the drive it’s something on the drive.

Bioses will sometimes use the drivers on disk if they can reach them.  That’s why pull the drive.

I just happened to have an USB drive laying around with Xubuntu Linux distro installed on it so I plugged it into the PC and booted Xubuntu from it via the live environment.

Both of the displays worked perfectly fine so I powered down the computer. After that I plugged in both of the drives and I was able to boot into Windows just fine.

One of the displays still doesn't work but it worked just fine on Linux.

 

Well at least I can actually use my computer now.

Thanks for the help.

 

Edit: after I left my computer on for around 15 minutes the other monitor started to work just fine while both being plugged into the GPU. I don't have a single idea as to why everything just works right now but I'm happy with it nonetheless.

 

Edit 2: after I restarted the computer both monitors are blank. However this time even unplugging the drives does nothing.

 

Edit 3: after a couple dozen of restarts or so one of the monitors finally works again. Now I've made backups of all of my important files in case I won't be able to boot up my PC again after shutting it down.

Good idea.  That it could work once in a couple dozen tries is in itself weird.  It should work 100% of the time or 0% of the time.  Does it fail if you also pull the video card and try to use the iGPU?

When I unplugged the GPU and used the iGPU nothing failed, even after multiple restarts.

Then I plugged in the GPU again and now both monitors work after multiple restarts.

Hopefully now things will work from now on.

If they work normally from now on it’s likely because the last restart you did included something different than the others.  Computers, or anything digital, aren’t normally a sometimes it works and sometimes it doesn’t kind of thing.
