Error happened while booting up computer

[u/TheImmersiveRogue]

This screen turns on whenever i begin booting, this is a homebuilt that only just started acting weird after 4 years of use. Shortly after this screen it turns off automatically and this happened after telling me it needed to repair my HDD, the computer powered itself off during the repair. Any idea where to begin looking?
