MSI 7750 not working on MSI 945GCM5-F V2 (FSB 1333)

HI,
I was going to upgrade a frends rig with 7750.
His configuration is
E6750
2gb DDR2
LC power 550W
and MSI 945GCM5-F V2 (FSB 1333) motherboard.
Problem is, the GPU is not recognised by the motherboard at all, and its not giving any signal on the screen when plugged in.
When I plug in the vga cable in the integrated VGA output, I get the picture, but I cant see 7750 in device manager.
Any leads?

  1. Try the GPU on another system, see if it works there. BTW what is the OS ? And you can try a BIOS update to the latest version, sometime it helps.

    Also you can try with another PSU(power supply unit).

    Hi, thank you for your answer. I m going to try to update to a latest BIOS version. I already tried another PSU and it didnt helped.
  3. Newest BIOS is up, and still nothing. GPU is working fine on
    Celeron G550, Asus P8H61 motherboard.

    I feel extremly stupid for believing that they care about compatibility.
    Fun fact, both motherboard and GPU are labeled as MSI and still not working.
  4. I cant believe no one knows anything about it.
    I set PCIE as primary, made CMOS reset, flashed BIOS, tested GPU in another system, tested more PSU.
    Anyone???
  5. It could be the PCI-E slot of the MB has gone bad or faulty. Try another GPU on the MB in question. See if it can detect the other GPU.
