Hello guys,
I bought from ebay a gpu that was describded as a gtx 750 ti, but in fact was a gtx 550 ti.
Now, I tried to flash to the proper bios using the CH341A programmer and this stuff.
The bios chip was the one below. (MX25L512)
My problem is, that after I reflashed the bios when I try to install the driver, when I go to device manager and scan for changes my screen goes black and I cannot do anything but shutting down/restarting the computer so my gpu is unusable.
What I need to mention is that before finding the proper bios chip on the cpu, I connected that programmer clip to the below chip (EM 5103) and I did some modifications there, so that could be the problem.
So what do you think? Is that the issue? If yes, what can I do about it? If not, what else could be the problem?
Thank you very much in advance.
