I am a very low budget gamer and i am facing a problem that my new gpu is not detecting by bios as my keyboard numlock key doesn't work and i have tested that same gpu and psu on other pc and it worked fine.
but not working with my new gpu.
(tried updating bios from 2011 to 2014)
1.should I install drivers for new gpu before installing it in my mobo?
2.whats the possible solution?
Specs:
i3 2100
mobo: 7033bm3
ram: 8gb (2gb x4)
old gpu: gt 610 (working fine)
new gpu : R7 260x xfx
