System constantly rebooting, no BOSD, possible chip or motherboard error, got stuck in bios update help

[Dimitri421]

I tried to upgrade my Motherboard on my System to the X570-A pro Board from MSI.

Have had constant crashes with it. The screen would just turn black and refuse to respond. After power cycling and getting it do function for a minute the eventviewer just said 'unexpected loss of power'

The indicator light on the MB kept saying CPU but knowing that the cpu had been stable for years before the MB swap (board was second hand) i eventually thought it probably isnt the CPU.

After going back to my old board for a while (seemed stable) i bought another board (Asus TUF gaming X570-plus).

After working perfectly for about two hours yesterday, when i turned the system on today it crashed within minutes.

This time it rebooted on its own, but woudnt stay on for more than a minute before crashing again.

Besides the 'unexpected loss of power' error, i found a bus/ interconnect error (picture attached).

Now. It had a pretty old BIOS installed so i figured that updating that might get rid of the issue, especially since a lot of the updates seemed to be for system stability fixes.

Well the BIOS froze mid install and i am currently in BIOS recovery mode.

It is instructing me to put the bios file on a usb drive and connect it, then to reset the PC.

I have done so, but end up just arriving back at the recovery mode screen.

Now i am afraid to turn my system of beccause it says not to.

I am really out of my dephts here so if anyone has ideas id be very greatful.

 

Some of my thoughts:

- When the system would work, stresstest were no problem. I seriously coudn't get it to crash.

- Back on the old board the cpu behaved again and everything was rocksolid

- The system behaved fine for a while (about a day) after i would reseat the CPU

- On the first MSI board, it seemed like the cpu just disconnected

- On the Asus board it reched the windows log in screen before dying again

- All of my parts are second hand (except for my boot drive) so no warranty

- The only new component was the MB but both of them having the same isssue is very suspect to me

- my old board had a  B350 chipset, maybe that one was less mean.

 

I would first like to resolve my little bios recovery mode issue so yeah.

help

 

UPDATE: Managed to get the BIOS updated (hopes and prayers probably) am running a stresstest currently to see if i can crash it again. Am probably going to reinstall windows too to eliminate that possibility

are you reinstalling windows each time or are you just booting the same windows installation thinking that it's 1995 and drive hopping is a windows feature rather than a happenstance

I am very much just booting into the same windows, now that you say that i see how that might be an issue. I just really dont want to. Its a pain in the a. but i can try that
