Computer won't recognise 270x on boot.

[Des123]

I've installed a new Gigabyte 270 into my system however when I press the power button, my monitor remains blank and it doesn't recognise any input. Resulting in me having to power the desktop on and off repeatedly until the card displays.
The graphics card, ram and power supply have been tested and are working.

I've done the following:
- Updated motherboard BIOS
- Tested the graphics card and PSU
- Changed BIOS settings to first display 'PEG' (Defaults back to auto every time)
- Tried another set of RAM
- Alternated between HDMI and DVI


Any help would be greatly appreciated!

Hi, have you had a look as to what your motherboard has as its default GPU device? It may be going to the integrated gpu automaticaly insteead of the r9 270x.

Yes. I've set the display first option in the BIOS to PEG. Still doesn't work.

Are there any other options you can select in that place youbselect peg?
