I bought and assembled 2x Deskmini X600 with 8700g and 2x 32GB Crucial DDR5-5600 and 4TB Kingston FURY Renegade.
Unfortunately, one PC just won't run properly, everything is exactly the same. But the picture sometimes just goes black and then crashes at some point. Or one monitor reports that the resolution doesn't meet the specifications, then the most I can see on another monitor is a mouse pointer, but I can't do anything except switch off the PC using the power button.
I've already reinstalled W11pro umpteen times, at first I thought it was just a corrupted Google Chrome profile because it was always running, but no.
Hardware compatibility according to Asrock website io. UEFI updates have done nothing. One PC has been running perfectly since Nov 2024, the other since April 2025 just doesn't want to...I don't know what to register for replacement. I would prefer to send in Deskmini X600 with 2x RAM (RAM test 24h io), AMD 8700g APU and SSD for testing, maybe a DIGITEC TECHNICIAN will find something?
Thank you for your detailed description. It's absolutely understandable that this annoys you, especially with two identically constructed systems.
Since you have reinstalled Windows several times, tested the RAM, updated the UEFI and checked the compatibility, there is a lot to be said for a possible hardware problem, perhaps on the mainboard, the APU or the SSD.
It is best to register a warranty check for the complete system including CPU, RAM and SSD via your customer account. You can mention in the comment that the other PC is running stably with an identical configuration and ask for a full technical inspection.
