With my Dell Inspiron desktop 3650 running Windows 10 I installed an AMD firepro v4800 graphics card, the installation was successful and the graphics card works well as expected. However when the computer is switched on or restarted the monitor does not switch on until the windows welcome screen so it is impossible to access the bios also if I try to access Recovery through Update and security the monitor switches off. I have tried a different card in there and exactly the same thing happens. If I take the card out the computer works on VGA as normal. Can anyone give me a solution or help me in finding one as I have tried every possibility I can think of.
