A few days ago when I turned on my computer it was displaying pixelated squares and lines through the screen and then it just went to a black screen after a few seconds. If I removed the graphics card from the computer and just used the integrated graphics it works perfectly fine. I therefore thought that the graphics card was the issue so I contacted amazon and they sent me a replacement, however the same thing is still happening with the new graphics card. I have tested the hdmi cable and the monitor and I know they are both working fine so I have no clue what the issue could be. Also if I boot with the hdmi plugged into the graphics card and then try to switch to the integrated graphics it does not work, I have to reboot the computer with the hdmi plugged into the motherboard for it to work.
For some reason I also cannot get into the bios when the graphics card is installed either, even if the hdmi cable is plugged into the motherboard. The graphics card has to be unplugged.
I built the computer just under a year ago and it has been fine until now.
Any help would be greatly appreciated.
