Gpu working but does not output a signal when in a specific mobo

[Theotterwins]

Hello
I recently decided to upgrade my rig to the lga 1155 platform and as it happened a friend offered me a spare 1155 motherboard. So I took it and transferred my working hd 7970 over and no signal.I get a signal from the integrated graphics. I got a signal from a spare r7 240 I had lying around but nothing from the 7970.

Specs:
i5 2500(not k)
cih61mi v1.1 (motherboard made by lenovo)
4gb 1600mhz dimm
hd 7970
corsair vs550 (550 watts)

I have tried changing the display. I have tried changing the output. I have tried changing the default graphics output in the bios.

Any help would be very much appreciated.

Do you try use DDU with r7 240 to uninstall the GPU driver before you use the HD7970? If no, try it. uninstall the GPU driver(s) in safe mode, shut down the PC, switch to the hd7970.

I am sorry for not being able to reply or test earlier but was celebrating my sister's 18th birthday.

Unfortunately, uninstalling my GPU drivers did not change anything.
I tried updating my motherboard bios but lenovo's bios scan said nothing needed to be updated.
