Hi there, Recently reformatted my computer and reinstalled Windows Vista. Since then, my graphics drivers have stopped working completely. My laptop has two model numbers (one says VGN-NS30E and another PCG-7164M), none of which correspond to any model on the Sony Vaio web support site. This is preventing me from playing Minecraft, Prison Architect & other Steam games. I have tried to manually download the Intel drivers (I believe I need the Intel Mobile Chipset) but they say my computer does not meet requirements. Really need any help and advice you all can give. Thanks in advance,
