Thank you for your response BigAl01,
Thank you for your respone3 months ago, I had ongoing sequential shutdowns that prevented me from working with my banking web account, email, as well as other online work, because after the unexpected reboot I was always locked out of my accounts and had the to always fix that.
I then sent in the mob to the selling point due guarantee and afterwards I bought me a Taichi (mob was refund) a new higher psu (titan, 850w). Windows11, I had to reinstall because I also replaced the ssd to rule out possible errors.
Thus, I did a clean install, but I had to go for the AMD chipset and raidexpert installation too, as I have a raid 10 with 4 disks on my pc.
The 5750x setup went well, I had it running for a few hours with all the AMD drivers on it without any problems, but since then, I didn't start it anymore for about 2 weeks, as I have the fear that the shutdowns will come back again.
Just to tell you why:
I bought me new components: AMD 7950X3D, Asrock Steel Legend X670E, AMD RX 6750 XT, 4 x 32GB Corsair Fury CMK64GX5M2B6000C40, bequiet dark power psu 850W, bequiet water cooler silent loop 2 and a bequiet silent base 802 tower. 3 new ssd WD black SN770 2TB. WD blue SN570 2 TB and a Samsung 990 Pro 1Tb.
1st installation with the only WD SN570 went ok, it started normal, but after 2 days being unbroken online it started to shutdown unexpectedly. And it didn't come back to normal again. So, I decided to get the WD black SN770 to do a new win11 install, which went ok and stayed stable for about 4 days. Putting back the SN570 as a secondary SSD went to sudden unexpected shutdowns randomly.
Boughr me the Samsung 990 pro 1TB ssd to do a clone of the SN770 drive-
Had that 990 pro ssd running for about 5 days (the other ssd on the mob) and suddenly it came back to shutdown unexpectedly.
The event viewer does show any identical related issues id, always completely different cause ids, so it is not objectively to get out what the root cause could be.
Out of that, my Omen HP Ryzen 5800H win11 and my Lenovo T410 notebooks (cross fingers ;-)) do not have such problems, they run error free! Also, the MSI pc from my older and the Asrock Taichi x99 from my younger boys run error free. I'm struggling, I'm a server engineer but do not have deep knowledge of client systems. My question is, are the main hardware and os companies not interested in an open development market for pc component availability? I'm lost here.
