X370 Taichi turning off and on repeatedly on boot

Hello,

I have recently come into a strange problem. When my PC goes into sleep mode, and I try to wake it, the motherboard shows 00 despite the fans still running. I have to manually power it off with the power button on my case. Once the PC is completely off, when I turn it back on the computer turns on for a second or two, then shuts off, it automatically turns back on, and shuts off again. It'll do this 4 or 5 times maybe until it finally works. Then everything goes as normal.

It is definitely worth noting that about 2 months ago installed Kubuntu as my default OS on a secondary SSD. I have Windows 10 Pro on an M.2 NVMe drive. Everything worked as normal for several months until yesterday when this problem occurred the first time.

I am unsure if this is related to a new hardware issue or not. I have had some issues with this motherboard in the past but nothing in a long time. I have not changed any settings in the UEFI/BIOS recently. My overclock has been completely stable since 2017.

My build:

CPU      AMD - Ryzen 7 1700 3.0GHz 8-Core Processor (Pstates OC 3.8 stable)
CPU Cooler      Corsair - H100i v2 70.7 CFM Liquid CPU Cooler
Motherboard      ASRock - X370 Taichi ATX AM4 Motherboard
Memory      G.Skill - Ripjaws V Series 16GB (2 x 8GB) DDR4-3200 Memory
Storage (Windows 10 Pro OS) Samsung 960 EVO 250GB M.2 NVMe SSD
Storage (Kubuntu Linux OS) Samsung 850 EVO SSD
Video Card      XFX - Radeon RX 480 8GB RS Video Card
Case      Phanteks - Enthoo Pro M Tempered Glass
Power Supply      SeaSonic FOCUS Plus Gold 850W

Please let me know if there is any other information I can provide.

Thank you

also to note what bios are you on ?

there were some pretty weird buggy x370 taichi bios versions released

i stayed on version 3.1 for all the time i ran the 1700 in mine
as it had no bugs and done the job nicely (only upgraded to a later bios to use the 3800x cpu)

Hello my friend, base on the above quote plus your title = turning off and on repeatedly on boot

I would like to remind "life expectancy" of the CPU is starting to degrade.

I'd second @RLGL a million %, dump the overclock.

Yes you didn't increase voltage, but default 3.4Ghz to 3.8Ghz for 3 years is not short.

Our 14nm is not as harden as previous....... say 45nm die. I'm not betting on 10 years life out of them......

My Phenom_II_965BE (45nm) only lasted 7 years with total accumulated overclock to 3.9Ghz less than 1 year duration (gaming only then OC), now it does not run stable at 3.4Ghz anymore. Gotto underclock and under volt to use as browser and video etc. Else crash and reboot randomly, a bit just like your case now.
