I have a z690 Classified bios 1.14, G.skill Trident Z5, 12700k, 850W power supply. I have been running the system for just over a month now and has been very stable up until recently I get either led codes 62, 69, or 7F while restarting from Windows 11 (freezes on only one of them at a time at random, but 69 is most common) with no post/no screen and I have to hold the power button to shut down and try again. And also at the same time as this started, sometimes when I wake it from sleep mode, it either freezes and restarts or I get a blue screen. When the PC is running it’s flawless, it’s only during restart or waking from sleep I have problems, but never during startup from being completely shut down. I’ve tried enabling/disabling fast boot, c states, reseating ram/ one stick at a time, and with or without GPU. I have no idea what else to try at this point. Could the MB be flaking out?
