Question New build - Not booting to BIOS. DRAM red light showing

[helpmee!]

Hi all,

I am hoping someone can give me a hand as I've been struggling for a week with this. I have a new build PC and on start, I can not boot to the BIOS and there is a red light showing on the mobo. No other red lights are on.

Things I have tried:
- Bought new RAM and checked compliance to the mobo
- Used combinations of RAM single and dual across all slots
- Double checked the connections to PSU for MOBO

My build is as follows:
- ASRock Z790 Steel Legend WiFi Intel DDR5 PCIe 5.0 ATX Motherboard - LGA 1700
- Intel Core i7 14700K, S 1700, Raptor Lake Refresh, 20 Cores, 28 Threads, 5.6GHz Turbo, 33MB Cache, 125W, Retail 7QYCY
- CORSAIR VENGEANCE RGB DDR5 RAM 32GB (2x16GB) 7200MHz CL34 Intel XMP iCUE Compatible Computer Memory - Black (CMH32GX5M2X7200C34)
or the replacement:
-CORSAIR VENGEANCE RGB DDR5 RAM 32GB (2x16GB) 6000MHz CL36 Intel XMP iCUE Compatible Computer Memory - Black (CMH32GX5M2D6000C36)
- NVIDIA GeForce RTX 4070 Founders Edition 12GB GDDR6X Graphics Card 7QWNT

Is there anything I can do or try?

I am aware that I need to update BIOS to use the new CPU, but can't boot to bios currently. I've also tried HDMI and displayport connections to the MOBO and the GPU, to see if this was the issue.

No system beeps... but I may have not plugged a cable in correctly (although can't see where)

There are 4 places where a red light might appear during the post process.
(boot, cpu, ram, vga)
What component does your red light show?

Your motherboard will boot with a 14700K on bios 9.03 which was released 6/21/2023.
Unless you bought very old stock, you should still be able to get to bios.

Simplify things.
Install your two sticks of ram in the recommended two slots.
Remove the 4070 and use the integrated graphics output from the motherboard.

Thanks! Ram light is showing. I took out the graphics card and plugged a hdmi into the mobo. Same issue unfortunately - blank screen, red light showing on mobo for ram. No bios!
