So I have a used 750ti I got from my job when I install it, it will intall the driver but then it gives me an error 43 in the Device Manager, I used DDU and installed many different drivers, I do have a version of windows tottally out of date but it doesnt feel like that would be the problem. So any ideas? Is it dead, I tried flashing its bios but it didnt like that and I'm not super experience in flashing. Am I doing something wrong? It is a cheap PNY version.
