HP Spectre x360 not booting up and cannot restore to a working backup

[Djdl]

After installing and loading a game, the laptop unexpectedly crashed. The laptop screen was just showing a black(ish) screen with white moving lines all over the place. The problem wasn't happening during start up and was being replicated on a separate screen. Therefore, I assumed it was nothing to do with the touch screen but to do with one of the graphics drivers. I then loaded up the repair options  to try and restore the laptop to previous working version. This was successful but the problem persisted. I tried to restore to an older version again but this option was no longer working.

Following this, I tried to perform an automatic repair, system restore, both locally and from the cloud, BIOS rollback and running the command prompt to try and troubleshoot the issue. Both SFC scannow and CHKDSK were unsuccessful as I couldn't access the drive windows was installed on.

As none of this was successful I ran the Symptom, System and Component tests, all of which passed. The laptop is now just showing the blue screen on start-up with the Stop code: CRITICAL_PROCESS_DIED.

What should my next steps be to resolve this issue?

The OS reinstall was successful but I’m now back to the original issue I faced. The laptop loads without issue, displaying the HP logo, but once it comes to the login screen, all I can see are a series of moving shapes and lines. The video checks all pass and the issue is replicated on a second screen. Please see attached screenshots.

Any idea what could be causing this issue and how it can be resolved?
