Windows 10: HP Envy Desktop 750-624 STUCK ON BOOT SCREEN! I don't know what to do or how to even...

I have not turned this PC on since the beginning of the pandemic 2020. I tried booting it up today no such luck its stuck on the hp logo screen with a circle wheel of dots ... for over an hour tried powering it off and booting again I got the same result. I do not know how or why this happening. How can this be fixed?HP ENVY DesktopOS Edition Windows 10 Homei7 - 7700 processor16 GIG RAM / 1TB HARD DRIVEVersion 19034CE7444QKF

HP Envy x360 with 1440p screen?

So I bought a refurb HP Envy x360 with the AMD FX 9800P and recently discovered I could set the screen resolution to 2560x1440 despite HP advertising this machine as only being capable of 1920x1080. Has anyone else bought one of these and found they could change the resolution to 1440P? I was thinking maybe since mine is a refurb that it was originally returned for some kind of screen issue and they replaced the screen with whatever they had lying around that day, which could well have been a screen meant for a Spectre, and not an Envy, since the Spectre does come with a 1440p screen. Would a mistake like this even be possible? It came in an Envy box and it says Envy everywhere on the laptop where it should say it. There is no external evidence that this might actually be a Spectre and not an Envy. So is this a fluke or all of these capable of displaying 1440p instead of being limited to 1080p as advertised?
