​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!
