I received this video card, without vents, only board and metal heating sink. I was told that it was used for minning btc.... When plugged inj to the computer no signs of life, motherboard/windoes doesnt recognise it...
I try to reprogram bios from some dump i found on the internet but no luck. Any ideas?

Your video card very good..ı am buy three month ago second hand gtx750,it is not work.I am first bga chip reflow but not work.After same you,search bios file but not find.I am disassembly bios and read(universal programmer)after save,again write.Very interesting work and still work.By the way,use with napkin and cellulosic thinner clean graphic card slot.I hope work your card too.

i found that one of the bios chip pm25ld010 is dead, shorting pin gnd to pin vcc. when i remove it no continuity between vcc and ground. tested the chip removed from the board showing short. Other chip is ok. But i do have continuity between vcc and hold on the board. I dont know is this normal because i dont have a boardview for this card...or there is short somewhere else? This card have bios switch' Does anyone have boardview? or the same card so he can test it with multimeter?
thank you
