I have a 600W psu and I have a intel i3 2120 that im trying to upgrade to become a gaming computer. My graphics card is plugged in and hooked up correctly and the fan is going but it doesnt display anything to the monitor and it does not show up in device manager. Does this mean the card is dead or the PCiE slot is dead. I have an h61m -hvs motherboard from asrock. The motherboard has been working fine. I just bought the motherboard and the gpu off craigslist and both said they tested and they are working correctly. Is there a way I can see if its the motherboard or if the GPU is dead.
