Pc various problems-dropouts-memtest86 not completed

[musictech]

Hi
i face a strange behaviour problem with my pc.
It is based on amd 3900x,asrock x570 steel legend,32 gb of ram.

I have some audio dropouts and sometimes my main working program freezes(cubase) .This is a behaviour that i have the last month.The previous 9 months i was working without problems.

Although i was able to run ''max gpu test'' and 3 minute test '' with success,i couldn't run the cpu coverage and ram test.
i got the message 'no perations during test period error''.

2 days ago i run also memtest86 from a usb stick and the system restarted.I don't know exactly what time it restarted cause i left it all night working but i know that the first 1-1:30 hour it was working fine.

 

I also run this cpu test https://cpux.net/cpu-stress-test-online and the pc restarted after 3-4 minutes running it.

 

i also geti this message in event viewer:

A corrected hardware error has occurred.

Reported by component: Processor Core
Error Source: Unknown Error Source
Error Type: Bus/Interconnect Error
Processor APIC ID: 0

The details view of this entry contains further information.

 

 

 

Another issue i have is that...i cannot login to microsoft account.I unistalled nvidia control panel and this is the only way to reinstall it but..it is not possible.Under settings--->my account i choose ''log in '' option but nothins happens!

 

finally...i saw this message in reliability history after a cubase crash:

This is difficult to say - but in my opinion its probably either RAM or mobo / bios.

 

Note just because it says processor doesn't necessarily mean that's it.

 

For example i had "corrected hw error " for the longest time (but without crashing) and it would always say "Nvidia device" ...

.turns out I needed a specific bios update and that fixed it.

Well one thing is to update the BIOS.

 

And post full system specs.
