Display Adapter failing to reset during boot and then subsequent factory reset attempts

[samthe030601]

I have the HP Paviion g6 with product number: BOP25PA#ACJ. This PC came with windows 7 pre-installed when I bought this. I upgraded it to windows 10 in 2015 during the free upgrade period. Everything worked absolutely fine until last month when the PC started to restart randomly and then never boot up to the home screen. It always led to the Bluescreen error page. I then decided to give it to the technician at my workplace as I had read really bad reviews about the HP Care Centre near my Location. The laptop was delivered to my son, while I was out on quarantine for the next two weeks. He had informed me about the laptop OS looking different and that's about it. I asked it to be delivered at my quarantine centre, where I got to know that he had apparently attempted two recovery attempts with no backup whatsoever when the same restart thing happened. When I got the laptop in my hands, it kept restarting without ever going to the homescreen, with mostly a bluecreen error stating "attempt to reset display driver and recover from timeout failed" and "PFN_LIST_CORRUPT". I looked up a few youtube tutorials and proceded to boot into safe mode and disable both the display adapters [ Radeon HD 7670M, Intel HD Graphics]. Then I connected my external HDD in which I had a backup of my PC from 2018. After updating the driver and restarting the PC, the same issue kept presenting itself again, with the PC booting up to the HP recovery page. After 4-5 unsuccessful recovery attempts, the PC booted up. I went and uninstalled all the display drivers. After further inspection, I got to know that I lost almost 340 GBs of storage (I don't know if that's a different issue to be tackled altogether), with only close to appx. 90GB as the total capacity of my HDD. The PC now is a clean version of Windows 7, with me later installing all the pre-installed HP software(s) from the backup that I had. While attempting to install windows 10 from the drive that I had, It wouldn't install with a later error message stating that my PC is in AUDIT Mode( which I've been unsuccessful in getting out from). I tried installing all the latest driver updates from the HP support website, which always then led to the bootloops (after which I've kept both the display drivers unistalled). I have also updated the BIOS. Disk Management shows I have 370GB of unallocated space( don't know if I still have my data somewhere).
