So I finally got my refunded power supply cause last week the problem was the dead on arrival psu I got but now there is another problem. When I was doing my test boot I saw all the lights on my motherboard turn on, the green one indicating power, the red ones around the pcie slot that my graphics card is inserted into and the red one next to the 24 pin ATX connector. The major problem however was that there was no video being displayed to my monitor, it just kept saying there was no dvi signal. Now I am lost and I just have no clue what to do, thank you for the help in advance.
