I think I've done everything right (the irony) but the system doesn't boot up and keeps restarting every 10 seconds. The fans (both the case and the H150i) seem to be working. The GPU's lights come on, the motherboard itself goes in full RGB mode and so does the USB keyboard. The monitor understands that there is an incoming signal (it lights up) but it doesn't show anything. I even removed one of the memory modules and the GPU completely (connected monitor to motherboard's HDMI out) and still no luck.
The motherboard has 3 ATX power connects:
- 4 pin
- 8 pin
- 24 pin
I could not install the M.2 in accordance with the motherboard's manual because a standoff was missing so I've removed it completely now, to no avail.
SSD and HDD power and SATA connectors are connected I can hear the HDD working.
What is the bare minimum a motherboard needs to have it booted? I basically wanna strip down the whole system to see what the problem is.
Thanks in advance
