Hi guys, so, I've been having this issue with my PC for a long time but Idk what causes this. I turn it on, all lights/fans works but I only see a black screen ( no peripherals works either). I know the GPU is fine because my monitor shows that something is connected to it, so the monitor recognizes that the GPU is there ( I don't receive any error message on the screen btw). After a few tries I could "fix" the problem but it keeps coming back. What is weird is that the solutions are completely random. Sometimes I just need to take a random RAM out(I have 3x4GB ) turn on the PC and it works just fine, than I put the same RAM back in and everything works again ( it doesn't matter which one I remove, it works again ) . Sometimes I need to take the GPU out, turn everything on ... it works ... than I stick the same GPU back and guess what ? PC works as if nothing had happened ! I can oftenly fix the trouble and put the PC to work but I have no freaking idea what is causing this. My guess is that something is wrong with the motherboard but I'm not sure. Do you guys have any idea what is causing this ? Is there anything I can do to try to permanent fix this ?
