r/ASUS on Reddit: Rapid blinking power LED on Asus Prime Z690-P WIFI

January 6, 2022 -

Hello,

I am wondering if anyone else has had the experience I have had...

I finally decided to build a new machine and have not been able to get it to boot yet. No matter what I try I get a rapidly blinking power LED.

Here is what I have:
- MOBO: Asus Prime Z690-P WIFI
- CPU: i7-12700K
- Cooler: Noctua NH-D15
- RAM: VENGEANCE 32GB (2x16GB) DDR5 DRAM 4800MHz C40 (CMK32GX5M2A4800C40)
- SSD: Samsung 970 Pro
- GPU: NVidia GTX 960

When I press the power button it appears to power on normally but I never get the BIOS post screen and monitor never turns on. The power LED starts flashing rapidly pretty much immediately. I tried swapping the RAM around all the possible slot combinations, tried removing it completely. I get beeps with memory error code with RAM completely removed. No beeps when the RAM is in. Tried 2 different GPU's. Checked and rechecked every connection. Removed and disconnected everything except the bare minimum and still get the same thing.

Any input appreciated.

Thanks.

Is it okay for the power LED to flash those 8-9 times as soon as I turn on the PC? Is it part of the Power On Self Test? Thanks in advance. ... Your system isn’t even getting past POST. Verify the socket has zero pins. Verify all cables. Essentially you should boot with only the CPU and memory installed, you should be able to confirm the system boots, by the diagnostic capability of the motherboard ... You should check what the blinks mean.
