Ok so I was messing arround on my pc and I was looking to improve my graphics because I saw that the pc was using the intel graphics card instead of my nvidia gtx 750, little did i know that disabling the intel graphics card would ruin my weekend... My monitor is old and i cant connect it to my graphics card (gpu) so it has to be connected to my motherboard... is there a way i can fix this or like some keyboard buttons that i can press to get my screen back on?
