yes my self build computer "died"on me. I have no idea how what or why except it was getting slow to power up . So had a “tinker” which did nothing so switched it off for a short time the powered it up.
At last the "splash"screens showed together with a Windows 11 self heal message. So whatever it was it sorted itself out and now back to normal.
Sometimes that may be all it needs. Glad it mended itself.
