Hi there, everyone. This morning I went to get a cup of coffee leaving it with a video paused on chrome and came back to a black backlit screen and one beep, with a delay that seemed like ages between each one. Does anyone have any advice as to what this could be? 

Edit: It's been such a hectic morning I forgot to post specs: It's an Aurora R4 - i73820 cpu liquid cooled, 16gb of ram (recently replaced due to fault), evga 970ftw+ (swapped in). If you need anything else please ask for it and I'll try to find it for you.
