What's happening : installed (added on my mobo ) a new GPU MSI radeon 7870 2GB OC on my MSI - Z77A-GD55 (bios updated up to v 1.11 the latest) once I installed it turned my PC on and my Monitor was still in Power Save mode , Switched the GPU to the lower PCIexpress socket still the same , changed cable to VGA with adapter (dvi) for the GPU since it has no pins for VGA , still the same , reset BIOS battery still the same, changed PCE GEN3 configs to AUTO (in bios) / Turned Multimonitor ON and switched to IGD / removed 1 of 2 ram sticks turned on , still the same .

Motherboard MSI - Z77A-GD55
GPU MSI radeon 7870 2GB OC
I cannot see the bios menu once turning PC on , unless my monitor to pc cable is connected on my mobo GPU (which im using now)
I don't know what else to do , is my PCI slots fried ? the mobo is brand new, its been working for a whole year that I have bought without problem (had this issue with my previous old GPU where it wouldnt get out of Power save mode , but switched/tweeked and it worked never touched it again , now got same issue but cant figure it out )
Any chance maybe my windows are broken / format might help ?
Are my pcie slots fried ? tried both GPUS new and old one they dont work in both top and lower sockets
