My ram lights up but no power to gpu or cpu. using the same setup and Noob $1000 Rig
That motherboard sitting on that Metal cover?
Sharp pins under the motherboard can short out on that metal cover
Otherwise, looks like you have 24 pin power and cpu power all plugged in, ready to go.
Still not working new board and power supply. removed gpu and still no boot in bio?
Hmmm Yo brotha does your MB make any sound when you turn it on, maybe something went wrong with the bios and you need to factory reset it
