Not getting any display with a new build, and I'm not sure how to identify which components are the problem.

• Intel 13700K

• Corsair Vengeance DDR5 5600 2x16GB (Model CMK32GX5M2B5600C36)

• Corsair SF750 PSU

• Glacier One 240 AIO

Trying to boot this up with the PCI riser & GPU unplugged because I need to boot to BIOS to set the PCI slot to use gen 3.

Tested with both sticks in - CPU and DRAM LEDs alternate for a few seconds, DRAM eventually stays lit. No display.

Tested each stick individually, in each channel - DRAM LED stays lit. No display.

AIO pump turns on, radiator fans spin. Tried re-seating every PSU connection, the CPU (didn't notice any bent pins), cleared CMOS. I highly doubt both ram sticks are defective, which makes me think the board is bad. Anything else I can try here?

Edit:

Probably need to update BIOS, but I can't update this board without a display. Looks like I'm buying a Celeron.

Edit x2 for anyone who stumbles on this: I ended up buying a 12th gen to get BIOS updated.
