This is my first time posting here so sorry if these are the wrong subforums!
The computer is an prebuilt hp envy h8-1419.
Last week I went to turn on the family computer and after the boot loading (where you see the HP logo with the loading circle underneath), a black screen appeared with a beep. I could move the mouse around and it seemed like basic functionality worked (I could turn on voice assistance) but I couldn't get it to load the desktop. CTRL-ALT-DEL didn't work either. I did see the power/hdd/cdrom lights on the tower working, but the hdd light was permanently on (not flashing) like it was stuck loading or something.
I tried rebooting a bunch of times and at one point I did get to the desktop, but it was glitched where the taskbar was a faded colour, the windows button didn't work, none of the desktop icons opened, and the right side of the screen had a black bar. Unfortunately, I shutdown the computer before thinking of trying ctrl-alt-del. I then tried to plug the desktop into another monitor and the same issue persisted so I doubt it was the graphics card.
Afterwards I ran HP's UEFI thing and did a start-up test: it failed at the "Hard Disk Short DST" test (it also gave me an error code that came up with nothing on Google). The HDD Smart, pci device, processor, and memory tests passed.
Next I booted into Recovery Mode and tried to use a restore point a week earlier, but after it was done the same issue still happened. I also randomly started getting a Windows Blue Screen Error 0xc0000225, which seems like a hard drive failure?
Then I tried refreshing using system recovery, but got a strange message, "The Drive where Windows is installed is locked." Automatic Repair also failed and told me to go to "system32/logfiles/srt/srttrail.txt", which is useless to me since I can't even load the desktop.
Afterwards I tried unplugging the hard drive and booting without it hoping it would reset everything. I reconnected the drive, but nothing changed except now in the cmd prompt it shows X: as the default drive instead of C: I think.
I tried using sfc /scannow, but got the error message, "Windows Resource protection could not start the repair service".
bootrec /rebuildbcd was met with another pointless message, "Total identified windows installations: 0; completed successfully".
Using chkdsk c: /f /x /r told me that "Windows scanned the file systems and found no problems"
At this point I unplugged the hard drive, plugged it into a different computer and found that I could access all of my files there fine. I'm currently scanning it with panda antivirus, but I doubt that will come up with anything.
Anyone might know what the problem is or what steps I should take next? I've been at it for 3 days scouring the internet for clues and nothing has been working. At this point I'm considering just backing up all my files and then doing a factory reset, although I'm not even sure if that will work.
