Frequent BSOD (~15 mins)

Hi there,

Typing quick, frequent crashes! Logs attached. Suspecting PSU/CPU failure, but trying to isolate before buying new one.

Symptoms are a screen freeze before Windows crash screen. Happening more frequently, under little/no load. Software independent, and has happened when I've left computer idle at Windows login screen after a recent crash (no mouse/keyboard activity).

Windows 10 Pro, Version 1903 (OS Build 18362.900).

Since crashes, I've disabled some audio drivers, updated graphics drivers, cleared out space on C:/ (35%+ available) and set my pagefile to system managed (wasn't before).

Thanks for any help! Will edit with more details, want to press submit before a crash.

Thanks. Should I hold out in updating BIOS if computer is unstable? Worried about bricking...

Temperatures are stable at about 40degC for CPU and 50degC for GPU. Under heavy load they both get to about 80degC. Small form factor. Both are normal for this build, it's been stable for two years. I've booted into Safe Mode and am leaving it running for a while to see what happens.
