Acer Veriton X4620G BIOS Unlock [Request]

[axizea]

Can someone please mod this BIOS for me. I have troubles in installing my new videocard ( Zotac GTX 1050 Mini ), just after my bios speaker beep once - a normal, all system good beep. My system won't boot and there's no display. I have tried to clean install windows 10 and still no luck.

my specs (if these will help)
cpu: i3-3220
ram:8gb ddr3
mobo: Acer b75h2-ad
hdd: 500gb 
gpu: xfx hd 6770
psu: generic 700w

yeah i know it's a poverty build, i don't want buy new mobo to replace my oem one. I'm a student so I can't afford to buy a new one, and I spent it all to buy that card.

here's the link,
