New build issues

Hi

I haven't built a PC in a long time and am struggling a bit here.

I have a 3900X with an arctic cooler II AIO, a strix 570-F and a 3080.

When I boot the PC the fans spin up, the logos glow on both the GFX card and the mobo, but I get no screen output. I'm using Display port.

Shortly after booting the GFX card fans spin down completely if that is significant.

Any ideas pleas?

Have you Tried switching dpi ports ?

You could try resetting the cmos on the motherboard.

Any diagnostic led lights or codes on the motherboard ?

Not initially, no. Modern GPU fans run at 0 RPM when idling soon after boot-up.

Thank you for your replies. Have fixed it. The 360mm rad which ran vertically in my case was preventing the GPU from sitting flush. Moved the rad to the top of the case and we're good. Many thanks.
