Hi all,
I've yet to have this issue building a PC, but I have it now. New build and everything is together, turns on, all fans come on, keyboard and mice light, case functions work (power, reset, etc) but I'm not able to get into the bios. I tried my monitor connection using HDMI first, then VGA, but nothing.

Here is what I have:
AMD Ryzen 5 3600
AsRock B450M Pro4 motherboard
INLAND 256GB I PREMIUM NVME SSD
WD Blue 3TB HDD
CRUCIAL 16GB 8X2 D4 3200CL16 BSLT
PowerSpec 550W PSU
No GPU installed (yet)
Cooler Master Q300P case

Any thoughts or ideas? I have the 24 pin and 8 pin CPU headers both connected with power, and nada...

Thanks in advance for any ideas.
