New PC - Problems

[Housey]

Just built my new PC

Added 4090 and 1200w and it starts fine. I can access the bios and can begin to install Windows 11....

However, it gets to the end of Windows 11 and goes to reboot, but never does. I get nothing on screen (I also note no fans on the GPU though it is lit up) and it seems to sit there with nothing showing.

Reinstalled Windows twice now and this keeps occurring. I am plugged in via the HDMI in Mono over HDMI on GPU as that was working but could that be the issues once Windows is installed?

Bit stuck.

Any video out from the on-board HDMI?

 

[Housey]

Yes that worked. I am beginning to think its my GPU that is the issue...

I have moved to Displayport and nothing is coming up at all now.

The motherboard is showing D6 = No Console Output Device Found

Have you updated the BIOS on the motherboard? If not I'd do that as part of the process just to rule out that.

You may also have to go into the bios and specify the card as the output device.

Thanks all. It was a faulty cable!

Up and running fine now
