Your computer isn't powering up.
Your computer isn't powering up.
The motherboard is showing lights but other parts aren't functioning. I checked the PSU using a paper clip, and fans started turning on when I connected the 24-pin cable. The lights appear but don't power anything. Please assist.
Is everything connected correctly? The GPU isn’t visible. RAM is set to A2 and B2?
You haven't connected the GP, and the PSU needs to be inside. Your RAM isn't set to dual-channel mode—review the motherboard guide; usually, they're placed in different slots for proper dual-channel operation.
Would be preferable yes; the i9-9900 includes an integrated GPU, so you should connect the monitor directly to the motherboard.
The computer fails to power up, leaving no output on the screen.
