Is my graphics card in?

Hi cool123ter
remove the card and check for any obstruction in the pci slot , try pushing back in the card firmly until you are sure it wont go in any further
and see if you can then close the flap
edit , be sure the clip at the end of the pcie slot is open and not closed , on the end of the card is like a small hook , make sure that where that hook goes into the board is open so that it can clip into place
