Acer Aspire M3970 graphic card upgrade and Alternative for rx 480

[Means]

I bought XFX Rx 480 8GB and this card is not booting;black screen.

Everything works well with my old graphic card AMD Radeon HD 7500.

I upgrade my PSU 600 W.

My bios is already on latest version (PO3-A3) that Acer release in 2012.

I also did all of these troubleshooting steps to

1)installed my AMD Radeon HD 7500. 2) update my mb bios to the last version. 3) Update win 10 to the last version (anniversary) and run CCleaner to hd and registry clean 4) run sfc/scannow on windows power shell. 5) Visual c++ 2013 installed. 6) installed DDU. 7) Create a restore point. 8) Download Crimson 16.7.2 WHQL package. 9) Run DDU (Safe mode, after a restart) and unistalled and cleaned old vga drivers. 10) Turn off the cpu. 11) Install RX 480. 12) Turn on cpu, load windows with basic vga drivers. 13) Installed the drivers that came with the board, through dvd.

I am planing to return the RX 480 and i am looking for the alternative for this card. PLZ leave some suggestions related to alternative graphic cards that have compatibility with my motherboard.

May try go into the BIOS, check the MB manual for how to disable "Secure Boot", and enable "Legacy Boot" by using the hd7500. After that shut down the pc, switch to the rx 480.

Does the MB have the "Legacy Boot" feature? If yes, just try it.

No there is no option like "Legacy Boot"

The PC used the Legacy BIOS already, and because the Acer does not provide more BIOS update, they do something in the BIOS so that the newer GPU is not compatible with that MB. I think you are out of luck. Sorry.
