I'm having trouble with my system not booting reliably. It often freezes during the boot process. Sometimes it gets as far as the ROG logo, but the loading spinner just stops. Other times, it fails even earlier. I've managed to log into Windows for about 10 seconds before the system reboots on its own. My specs are:
- CPU: AMD Ryzen 9 5900X
- Motherboard: ASUS ROG Crosshair VIII Dark Hero
- GPU: NVIDIA GeForce RTX 4070 (also tested with GTX 1080 Ti)
- RAM: 4× Corsair Vengeance LPX CMK16GX4M2B3200C16
- Storage: NVMe SSD (also tried booting from Ubuntu USB)
- Platform: AM4
I've already done a lot of troubleshooting, like testing the RAM, checking cables, replacing the CMOS battery, and reseating the hardware. I also verified and updated the BIOS and tried different boot devices. Some Q-codes I've seen when it freezes are AA, 07, 42, A2, and 9E. Is there anything else I could try, or do you think it's time to upgrade to AM5 and DDR5? It feels frustrating to think I might need to replace everything. By the way, I've ordered a new PSU as well, hoping that's the culprit.

Have you tried taking the SSD out and booting again from the USB? It could be that the SSD is causing some issues during the boot. If that doesn't work, then it might really be the PSU that's causing the freezes. Good luck!

I did try without the SSD, so looks like I need to get that new PSU after all.
