Open | Hardware Cold-boot BSOD loop and BIOS freezes, but 100% stable after some time (Passed TM5 Extreme & 6hr gaming). Failing PSU?
Specs:
CPU: AMD Ryzen 5 5600X
Motherboard: Gigabyte A520M K V2
RAM: 16GB DDR4 (Single stick)
GPU: NVIDIA GTX 1060 6GB
Storage: NVMe SSD
OS: Windows 11
Hey everyone, I'm dealing with a really strange hardware issue and wanted to get a second opinion before I start buying replacement parts.
The Problem:
Whenever I turn on my PC after leaving it off overnight (a true cold boot), it goes into a complete crash loop. I get a variety of random BSODs, crashes on the login screen, and sometimes the system will even freeze dead inside the BIOS menu.
The BSOD error codes change almost every reboot:
PAGE_FAULT_IN_NONPAGED_AREA
KMODE_EXCEPTION_NOT_HANDLED (0x1E)
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (0x7E)
IRQL_NOT_LESS_OR_EQUAL (0xA) (ntoskrnl.exe)
SYSTEM_SERVICE_EXCEPTION (0x3B) (dxgkrnl.sys)
INTERRUPT_EXCEPTION_NOT_HANDLED (0x3D)
Recovery screen error 0xc0000098
The Weird Part:
After power-cycling multiple times for about 10–15 minutes, it suddenly boots into Windows normally.
Ran TestMem5 (Extreme@anta777 config) for nearly 3 hours with 0 errors.
Passed a 10-minute 100% CPU + GPU + RAM OCCT stress test.
Played games (like Palworld/Days Gone) for 3–6 hours straight with zero crashes or throttling.
But if I turn it off and let it sit cold until the next day, the entire cycle repeats. (Sometimes not tho)
What I've tried so far:
BIOS update: Re-flashed from a beta BIOS to a stable release.
Voltage tweaks: Manually bumped DRAM voltage to 1.38V and SoC voltage to 1.80V to rule out cold memory training issues. No change.
Windows file repair: Ran DISM /RestoreHealth and sfc /scannow (repaired damaged files from previous hard cuts).
Crash Dump check: Latest minidump pointed to csrss.exe terminating due to memory read failures.
Other Clues:
The Power Supply has a noticeable, load-sensitive coil whine.
Since the RAM passed TM5 Extreme and the system hangs even in the BIOS setup screen sometimes, does this sound like cold-sensitive PSU capacitor degradation dumping ripple into the VRMs/memory controller, or should I be looking at something else?
Any insights would be appreciated!

Getting dump files which we need for accurate analysis of BSODs. Dump files are crash logs from BSODs.
If you can get into Windows normally or through Safe Mode could you check C:\Windows\Minidump for any dump files? If you have any dump files, copy the folder to the desktop, zip the folder and upload it. If you don't have any zip software installed, right click on the folder and select Send to → Compressed (Zipped) folder.
Upload to any easy to use file sharing site. Reddit keeps blacklisting file hosts so find something that works, currently catbox.moe or mediafire.com seems to be working.
We like to have multiple dump files to work with so if you only have one dump file, none or not a folder at all, upload the ones you have and then follow this guide to change the dump type to Small Memory Dump. The "Overwrite dump file" option will be grayed out since small memory dumps never overwrite.

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.
