EZ Debug LED: Debug LED indicators
These LEDs indicate the status of the motherboard.
CPU - indicates CPU is not detected or fail.
DRAM - indicates DRAM is not detected or fail.
VGA - indicates GPU is not detected or fail.
BOOT - indicates booting device is not detected or fail.
They’re on the right side of the mobo next to the RAM slot, above the ATX power supply connector.
If the diagnostic LEDs aren’t OK… check that the power supply cable (Big 24-pin, middle right edge) is fully seated.
Check that CPU power is connected (8-pin, top right)
Check for extra standoffs.
Try different output connectors on the GPU.
My Nvidia card displays the POST/BIOS on the rightmost used output connector, but I can’t remember what my 10xx did. I think it was DVI, HDMI, then DP.
Anyway, might wanna use a single monitor until you figure this out and make sure it uses that input, had a weird monitor the outre day that would default to some random input even if it was unplugged.
