At first occasionally starting the pc would take me straight to bios, I would reset my pc and it would start normally and be fine. This happened maybe 3-4 times over about a month then out of no where in the middle of a game I get this blue screen message WHEA Uncorrectable error and in restart I go straight to UEFI BIOS where it says I have no bootable devices under boot priority.This is a custom pc I have built with very minimal knowledge and YouTube videos about a year ago has worked perfect until now. I have played around with the ram removing and refitting which will get me to a blue troubleshoot page but can’t get any further. I’m at the point of frustration I’d factory reset if I knew it would fix it.
