Hello there. So, I have this old desktop computer that is giving me a black screen when I turn it on. I replaced the PSU, but it wasn't that. Given that I had no spare parts to swap one by one, nor did I have a multimeter or any other equipment of the sort that could help me troubleshooting the issue, I decided to take it a computer shop. I was forced to remove the board from the case before taking it to them, so they had to test it on some other case. Anyway, they told me the capacitors were bad, they fixed it and returned me the board. I got home, put the board back on the case and connected everything, just to find out that it's still displaying a black screen.
What you guys think it could be? I no longer have the board's manual and I couldn't find it anywhere online. So there is a slight possibility that I might have it plugged incorrectly, but I find that unlikely since I took a picture of the board and its connectors in place, prior to even touching it. Other than it being my own fault, I can only think that it may be the case's power connector that is faulty. And since they ran tests on the board, I take it that the RAM and the processor can't be blamed. I even removed all of the other front panel connectors and left only the power connector plugged (you only need that one plugged in order for the computer to boot up, right?), just in case one of them was faulty and was stopping the computer from starting up properly.
