Ok My computer was working fine and then when I turn it on My monitor stays black, I thought that maybe it was my power supply or motherboard so i bought a new motherboard and a new power supply. The same thing happanes again. I tried it with 4 different motherboards and it still stays black, it dosnt even turn on. My computer turns on but not the monitor, then I thought that maybe my monitor was messed up so i turned a different monitor and same problem. Please help me.
