B760 aorus elite no graphics output

[Blast3r]

Hi this is doing my head in, I enable safe boot in the bios and when it rebooted it has no graphics output, I have a AMD 7900XT with an intel 13600kf processor and it was work faultless for 2 years, I tried reset bios etc but it won't clear the issue so did all the usual unseated everything and back in, tried a different gpu in and nothing I'm afraid I've bricked it!!!! I can't even use the MB hdmi as my processor has no graphics built in....any help is appreciated as the gigabyte tech help are not getting back to me, has anyone had this before?? Thanks in advance

Pull the power plug out. Hold down the power button for 15 or 20 sec. That drain all the power out the PSU. Pull out the battery? Let sit for about hour. Then put it back in and see what happens.

If that doesn't work. What bios is on the board? You could try to do bios update using the quick flash button on the MB. That might bring it back to life.
