Issue:
Most of the time when I power on my computer the monitor gets no signal from my video card and stays blank. Everything else appears to be working, including the lights and fans on my video card. But if I power on the computer, wait for it to have no signal, and then restart it by holding the restart button on the case the monitor WILL work perfectly and display the signal, showing full POST and Windows 10. It seems like there is some weird handshake or communication issue between the motherboard and video card... I'm stumped. I've also considered maybe it's a RAM issue since this is DDR5-6000 but the CPU only supports 5600?
Video of boot process showing no signal then I restart the PC at 0:57 and then the video signal works
Things I've already tried:
- The video card, power supply, and monitor all work perfectly fine in a different build
- Different display cables and HDMI cables going from my video card to monitor
- Different PSU -> video card power cables
- Different VGA power cable port on PSU
- Reseat video card and RAM many times, including trying each RAM stick individually
- Flash BIOS to newest version / Clear CMOS *
- Disabling fast boot in BIOS
- Stock RAM frequencies (Auto), XMP 1 and 2

EDIT - ADDING MY THOUGHTS NOW THAT THE ISSUE IS "FIXED" IN CASE SOMEONE FINDS THIS IN THE FUTURE.
I ended up getting a replacement board and everything is now working fine. I think my original problem may have been caused by one or both of these:
- With the first non-working board, I remember I installed the 13th gen CPU BEFORE updating the bios to a version which supported the 13th gen CPU. Once I realized I needed to do that I updated the bios firmware from the Asus site but the problem persisted. I'm wondering if there is an order of operations issue where a CPU without integrated graphics needs to be installed after the mobo supports it? This is really the only root cause I can think of.
- Some weird issue with the board - I did originally buy it second hand so there's always a chance there was some issue that I couldn't control.
