If you are using graphics card then open card from one pcie slot and add to another slot. Before doing this not press hard to install or uninstall card.

Secondly if your motherboard has inbuilt graphics port then check it up by connecting VGA dvi or hdmi.

Thirdly check your ram if they are working. Try to hear beep sound after switch on your system. Three long beep indicate ram error or slot malfunction etc.

If problem persist it send it to hardware section
