All my parts are plugged in, but my computer doesn't display to the monitor. I have an Asus ROG X Hero and a Radeon RX 580. I also initially mistakenly plugged the CPU power into the GPU before correcting that. Could I have some assistance as to what the problem may be?
Did you powered on the pc when the cpu power was into gpu?
If so, you might burned out the gpu.
Cause the cpu power pin is hard, near impossible to plug into gpu because every connector has notches which coreespond the plug that is made for.
My specs include a Corsair 2 x 16 gb ram ddr4, a firepower silencer mk3 750w, ASUS ROG x Hero, Intel i7-870k 3.7 GHz 6 core, Corsair hydro h100i, Pioneer BDR 211UBK, a Seagate Barracuda pro 4TB and a Crucial MX300 ME 1TB SSD
No Bueno, honestly man get some help at this point, the fact that you plugged cpu power into gpu may have cause some irreparable damage. Get to a pc repair shop or good knowledgeable friend asap. You have nice hardware and no sense causing any more damage if not necessary
