Built a Win 10 based video editing / rendering system on thanksgiving with a Gigabyte X570 AORUS ELITE (x570) MB, 128GB RAM, NVME SSD, Seasonic PS, EVGA 3080 GPU, and Ryzen 5950x CPU. Everything ran great for a couple months until a few days ago. Daily editing / nightly rendering so it was cranking moderately to heavy during this time period. All stock settings, nothing overclocked.
The other morning noticed the box was in a Windows boot loop. Post, OS tries to load / crash before GUI pop / reboot, etc. First figured a MS patch bomb messed something up. Luckily we have a local Synology with Active Backup imaging in place so we get a nightly backup going back 90 days. Plan was to simply boot from the Synology PE based recovery thumb drive & restore a recent image.
Attempted to boot from the PE recovery USB drive and just before the GUI was expected the system would reboot just as with the OS loading from the SSD. Immediately figured hardware issue somewhere. Removed the SSD completely and then tried booting from the thumb drive with just a single memory stick in (tried all four one 1x1) but same resulting reboot / crash. Next step was to pull the video card and replace with a working 20 series. Same result - crash.
Next ordered a replacement identical motherboard from Amazon & installed. Boot from SSD would still crash but for a while at least botting from the thumb drive was successful. Figured corrupt OS image. Since PE was now (temporarily) working restored the OS from a couple days back but still crash on first boot. Then all of a sudden during another OS restore attempt PE crashed and then on all subsequent boot attempts crash.
Now what? Only part left is the CPU but if I can't even get into PE how can I run a CPU test /diag? Does AMD have a bootable test image of some kind? Do you concur all other components as the troubleshooting process described above are OK and it must be the CPU? Will AMD replace the CPU under warranty?
