Hello!

I just bought a new GPU (It's the Gigabyte Radeon Rx460 4GB) and some weird things happened: The first time I plugged it in (I think I did it properly, the fans were working) there was no signal on my computers monitor. It wouldn't even show the BIOS screen and when I tried connecting the HDMI to the motherboard I would get no signal there aswell. The computer was powered up and would stay up indefinetely. The other weird thing I noticed is that when I decided to shut it down, it turned off instantly when I pressed the power button (normally I have to hold it in for some seconds). After that I decided to plug in my old GPU so that I can have access to my computer. However, as soon as I plugged in my old GPU my motherboard ( Gigabyte H77M-D3H) went into a boot loop (10secs and then restart) with nothing on my screen aswell. Upon researching that I realised that my BIOS has been corrupted so I had to remove the motherboard battery and then load it from the 2nd BIOS (my motherboard has a double BIOS). After that my computer is working as it used to with the old GPU. When I tried plugging the new GPU, there was no signal again but at least it didn't lead to the whole BIOS corruption incident.

So my question is how do I get the new GPU to function properly? As far as I checked, it is compatible with my motherboard.

My main suspicion is that the BIOS of my motherboard is really outdated (I checked it and it is a 2012 date). Do you think that a BIOS update would solve the problem? The latest version on the Gigabyte site is a 2014 version.

Thank you in advance!
 
what psu do you have? are sure its not bcs of bad gpu? what is your old gpu? are sure that you have already uninstalled the old drivers before plugging in your new gpu? have you tried switching it to iGPU to see if it works? maybe one of those could be a solution.
