I've just bought my first ever pc and it's a prebuilt gaming pc and I've connected all the correct cables to each other, the pc seems to run fine but the monitor still keeps saying it has no signal... what do I do?
 
Solution
Well assuming it is powering on, lights and fans turn on etc. Make sure you are plugging your display cable into the back of the GPU and not the motherboard.
