Hi folks, random issue that I'm hoping someone has encountered before. New PC built around 6 weeks ago, all running fine. New monitor bought a week ago, all running fine.

Specs as follows:

MSI B-350M Arctic MB

Ryzen 1500 CPU

8gb ram

Geforce GTX1050ti video card running AOC 27" via DP and Acer 24" via DVI

WD Green 240gb M.2 SSD - boot drive

WD Blue 2tb HDD

EVGA 650w PSU.


Over the weekend, unable to detect bootable device after working fine the night before. Check the bios, and sure enough it isn't there - the other HDD is there though.

Start pulling it apart, and as soon as I disconnect one of the monitors (AOC 27" via DP) the red debug light turns off. System boots normally. Plug monitor back in. Runs fine. Happy days...


Rinse repeat, every time I shut down, the red light for Boot failure comes on the MB. 


Has anyone ever encountered this before, and if so what's causing it? Asking the retailers is getting me nothing, no replies at all. 


Any insight would be great as this is driving me nuts.


Thanks in advance!

Try going to the control panel, to device manager, the monitors and uninstall all monitors then reboot.
