Hello everyone,
I’m not sure what I did, but I changed the wrong BIOS on my GTX 570 HD (2.5GB from EVGA). Now the PC boots but there’s no signal detected. Windows doesn’t recognize it at all, and Device Manager shows nothing. I’m currently using my IGPU. Nvflash says there are no NVIDIA diplays found and I’m stuck. Did I cause a problem? Is the system dead, Jim? Please help me.
Thank you Alex

Is there a bios switch available on the GPU? Are you referring to nvflash no longer recognizing your GPU? If neither applies, you'll likely need a GPU upgrade. Could you share your system specifications?
