Dear Vince,
Thank you for the posting.

According to your description, the problem may relate to the compatibility of the CPU and memory, please refer to the following suggestions to verify.

1. Clear CMOS by referring to user manual page. 27.
User manual: https://download.asrock.com/Manual/B550%20Phantom%20Gaming%204ac.pdf
2. Only install CPU, PSU, Cooler, RAM, Graphic card to check if the system can boot into BIOS setup.
3. Install one stick RAM on each slots by turns to repeat suggestion 2 to check if the problem relates to specific RAM stick or slot.
4. If possible, please use other CPU and RAM to cross test to check if the problem relate to the compatibility of the memory and CPU.

Thank you,

Best wishes,
ASRock TSD]]> Thu, 07 Jan 2021 15:07:16 +0000 https://forum.asrock.com/forum_posts.asp?TID=17711&PID=82883&title=new-build-pc-wont-boot#82883 https://forum.asrock.com/forum_posts.asp?TID=17711&PID=82782&title=new-build-pc-wont-boot#82782 Author: VinceL

I have build a new pc, and it won't boot. No video at all. The CPU and DRAM red LED lights are lighting up on the mobo on pwoer-on

CPU - AMD Ryzen 5 3600XT
MOBO - ASRock B550 Phantom Gaming 4 AC
RAM - Crucial Ballistix 3200 MHz DDR4 DRAM (16GBx2)
STORAGE - Western Digital 1TB WD Blue SN550 NVMe SSD
VIDEO - XFX RX 5600 XT THICC II PRO

No OS is installed yet. I can't even get to the BIOS screen - I get no video at all.

I don't have any other desktop computers, so I can't swap components to test what is working and what is not working.

Any help would be greatly appreciated.]]> Mon, 04 Jan 2021 06:55:00 +0000 https://forum.asrock.com/forum_posts.asp?TID=17711&PID=82782&title=new-build-pc-wont-boot#82782
