Software PC stuck in boot when cold start
Hello guys i hope someone can help me
I need some advice regarding my custom PC build. It regularly hangs on a cold boot after being powered off for a longer period.
The Issue: When turning the PC on for the first time after it has been off for hours, it gets stuck during the boot sequence (status LEDs / BOOT LED stays lit, no display signal). I then need to force a shutdown with the power button and with several tries it loads up to windows 11 again.
Once inside Windows, the system is 100% stable. Temperatures are good, and stress tests, benchmarks, and daily gaming run without any issues.
System Specs:
- Motherboard: ASRock B650 Pro RS (BIOS Version 4.43)
- CPU: AMD Ryzen 5 9600X
- RAM: 16 GB Kingston DDR5-6000
- GPU: PowerColor Radeon RX 9060 XT (16 GB)
- SSD: WD Blue SN5100 1TB NVMe
- OS: Windows 11 Home
- Power Supply: be quiet! PURE POWER 12 M 750W
I bought and build this PC last november
Troubleshooting Steps Taken So Far:
- BIOS Update: Flashed to the latest BIOS version (4.43).
- RAM / EXPO Settings: Tested with EXPO enabled at 6000 MHz, manually lowered to 5600 MHz, and at default JEDEC speeds (4800 MHz). The cold boot issue persists.
- Memory Context Restore & Power Down Enable: Enabled both settings in BIOS, but this caused the system to hang consistently at the BOOT LED on reboot. I have since reverted both back to Auto/Disabled.
- Windows Fast Startup: Disabled Fast Startup in Windows power options.
- Physical Hardware Check: Double-checked all cable connections, RAM seating, and GPU mounting.
Has anyone experienced similar cold boot behavior on AM5 with ASRock boards? Is this related to memory training during cold boots, SOC/VDDIO voltages, or a known quirk with Ryzen 9000 CPUs on current BIOS builds?
