Windows 10: PC Restarts Itself, then Stuck on POST

Hi, my sister's PC has been seriously unstable over this month. PC oftenly restarts itself and then stuck on POST. At first, this is only happening max. once in a day. Now it got worse, I can't even use Windows more than 30 minutes, as the PC will restart again and stuck. The specs are :

AMD Thuban 1090T
MSI 890FXA-GD70
2x8GB Corsair Vengeance DDR3
AMD Radeon RX 550 4GB
WDC Green 2TB
Enermax NAXN 500W

The BIOS stuck with either "Initializing USB controller" or "Initializing USB controller...Done", Normally, IIRC, after showing those info, POST checks RAM and HDD. So I did some tests :

Things I did :
1. Resetting RAM on all sockets, this including only use 1 stick on each socket
2. Use different GPU card (Radeon R7 260X 1GB)
3. Clean up disk space in all partitions so the bar on Windows Explorer stays on blue
4. Unplug the SATA data cable from HDD (No disk in the PC) and let the PC boots with Ubuntu 18.04 live USB

It didn't solve the problem, even when I "Try" Ubuntu from live USB, PC seems to lose power and stuck again on POST. When this problem occurs, the LED debug code on mobo shows "38" (or "3B"?). I'm positive this is not a temperature as when I start the PC anytime it goes around ~40c.

Next component I suspect could be the issue is the PSU, but it's relatively new (2 years old) so I doubt it and it seems other components (LEDs, system fan, USB ports, etc) running just fine. So I'm stuck with the processor or mainboard, both bought from late 2010 (8yo), but I don't have any spare processor and mainboard right now. Both processor and mainboard temperature sensors, from what I can see in HWMonitor, is around 40c-50c.

Could processor/mainboard be the issue? And how to determine that either of them is the problem?

Thanks in advance

Inexplicable restarts


Thanks for your patient help and analysis, zbook. I'll step through some of your suggestions over the next few days - there's a lot to do and some look a bit hairy! That is, for a PC that is working sweetly right now...

Meanwhile, as requested in the BSOD thread (sorry, I misunderstood and posted there by mistake), I've attached both ZIP files.

One step I did try right away was to answer your question about whether my BIOS is up-to-date. I had no success at the AMI site but did get some info from this commercial site:





It was one of the '9' (I counted 10) listed here:
