It doesn't matter if you just got the PSU
Sitting in the warehouse for months, years even, can damage it
So, the GPU works. 100% confirmed
Does your motherboard and CPU work 100%. not 99%, 100%?
If yes, i'm willing to bet the PSUs DOA (dead on arrival)
Does the PSU fan spin?
PSU fan spins, motherboard lights turn on, CPU fan turns on, everything turns on except the graphics card.
did you have a look over that other guide? maybe the 4 pin is out. A family member had the same thing, everything turned on, lights, fans but there was no video signal
because your GPU work on another computer, we know for a fact the GPU works fine.
You have to check each component to find out what is broke
GPU, mobo etc
Did your computer turn on before installing the graphics card or was it build all together?
