So I've had my current setup for going on 2 and a half years now. It's my first build, I've leaned alot there have been minor hickups here and there but for the most part it's been a pretty solid machine...until recently. It started by having weird issues where I'd put it in sleep mode then it would take forever to get there but then it would start up almost instantly. Also it wouldn't turn the display off after 15 minutes. Not sure if that is relevant, but the issue I'm having now is it will out of no where, restart and then show the ASUS boot screen, then go to a screen that says "Reboot and select a proper boot device or insert boot media in selected boot device and press a key." Sometimes I can restart it repetitively and it will boot but usually it's short lived. When it does this, I've swapped an SSD in to see if it was my hard drive and I get the same result which leaves me to believe its the motherboard. Anyone had this happen to them? Any help would be greatly appreciated. Thanks!
