Yeah, you are right. I asked EVGA to replace my PSU (which is under warranty), and the problem was fixed. I tested the old PSU, and it only outputs 11.50 V.]]> Tue, 08 Apr 2025 03:43:53 +0000 https://forum.asrock.com/forum_posts.asp?TID=101351&PID=190020&title=pc-wont-boot-but-mb-led-flashing#190020 <![CDATA[PC Won't boot but MB LED flashing : Sounds to me like your power supply...]]> https://forum.asrock.com/forum_posts.asp?TID=101351&PID=185704&title=pc-wont-boot-but-mb-led-flashing#185704 Author: eccential

Sounds to me like your power supply crapped out.

Hello Everyone,

My PC spec is the Asrock B550M Steel Legend MB, AMD 5900x CPU, and 3080ti GPU.

My PC suddenly shut off while I was playing a game, and now it won?™t turn on. The fans do not spin when I push the PC power-on button. However, the on-board LED lights flash white when the PSU is turned on.

I have attempted the following troubleshooting steps:

Cleared the CMOS by removing the CR2032 battery
Used the back clear-CMOS button
Held the power button for 15 seconds

Unfortunately, none of these steps resolved the issue. Do you guys have any clue how to fix this issue?

Thank you for your assistance.]]> Tue, 18 Mar 2025 00:20:17 +0000 https://forum.asrock.com/forum_posts.asp?TID=101351&PID=185695&title=pc-wont-boot-but-mb-led-flashing#185695
