All 3 monitors are black, did something wrong with NVidia GTX 770

Sorry, I wasn't clear. When the PC is on, if you force a shut down but pressing and holding the Power button, Windows should register that as an abnormal shut down and display a menu when you next power on the PC.

On this menu, you should be able to select Safe mode with Networking and reset your graphics settings.

Let me know how you get on.

Again thanks. I have a Game computer from Medion. I tried to turn it on and than pressing one of the function keys. I only get sometimes the splash screen with the name MEDION for a very short time and dots moving in a circle below it. Tried all the function keys.

Wait until the PC has loaded windows and if your screens are still blank then press and hold the PC Power button to shut down the PC. When it has completely shut down, switch back on and don't press any keys, you should get the recovery menu displayed. If so select Safe mode with Networking.

Tried it 3 times. Got the Medion screen with the circular moving dots every time but than it went all black again. The second time I got the sound of an error message, but naturaly I could not see it.

I've carried this out on my PC and it works via key strokes [You need to follow exactly....]

1/ Switch your PC on and let it start normally
2/ Press Windows key
3/ Press Up arrow twice
4/ Press Enter
5/ Press Up arrow once
6/ Press and hold Shift and then press Enter

The PC should reboot into safe mode. Let me know how you get on.

I appreciate your help very much. Tried the above exactly 3 times. The result is the same as before: Black screen after Medion.
What do you think of changing the Graphics card for an older one, or puting it in as extra so I can at least maybe see something? The problem is maybe caused by booting from the SSD and to fast for any keystroke.

You could try connecting your monitor to the built-in graphics card - may need to enable in BIOS...

I tried that for both connections (one HDMI). The PC gives in both cases a beep followed by two short ones and continued that until I switched off the PC.

Hi

I wonder if the reason for the POST fail is that your on-board graphics is disabled. With your monitors plugged into the graphics card, are you able to enter the BIOS and enable the on-board graphics and then re-connect your monitor to the on-board?

Good morning,
With the monitors plugged into the graphics card the screens are black. I have never entered the BIOS before, what is the procedure in case I get one day a working screen?

Hi

Before windows starts is any text displayed on one of the monitors? If so, it should say display a message to press the 'del' key to modify the BIOS.

If you are able to, select 'on board devices' and enable the on board graphics card then save and exit the BIOS. The machine will now restart and you should be able to plug one of your monitors into the DVI port on the main PC.
