I have just bought an "Asus AMD Radeon HD 7770 2GB GDDR5 PCI-E 3.0". I have plugged it into my "ASUS M4A88TD-V EVO/USB3" and I can not see the graphics card in the device manager.
The graphics card is powered (the red led on the main board is on) and the fans are on, but I can see no sign of it... I THINK I have the BIOS set right, but I fail to see what I could have done at BIOS level to disable the PCI. I have BIOS version "2301". Does anyone know where I could begin debugging this please? Many thanks, Alec
 
Do you have your monitor plugged into the ondie gpu or the 7770? Try it in the 7770 and it will probably be auto detected as the default and you will be good to go. If that fails you probably need to disable the ondie GPU in the bios and set the main one as PCIE/PEG
