it happened again, so i just wait to see what will happen next, : black screen and i had a hard time to successfully reboot the os i had to unplug it the go to my bios and change the igp allocation that value get back from 1024 to 32 mb so probably a graphic card and igpu problem nobody has an idea yet?

just experienced the same thing. eventually the system reboots. works fine for a couple of minutes...then that thing happens weird. did a full install from scratch yesterday so was not expecting this at all.

any ideas? Using Radeon card... so not the onboard igp
Made some changes in the bios and hopefully that fixed it.... weird **** do

I have exactly the same problem on one of my builds (Thomas3). Same mobo, but with RX570. And I'm running High Sierra.
System randomly freezes (unresponsive and no network) and mouse becomes weird square.
I'll try to disable "launch CSM" in bios.
All help is welcome!

I'll try to disable "launch CSM" in bios.

Disabling "launch CSM" did the trick!
