SetsulPowershell seems unlikely, I doubt you've been messing with individual blocks in the paging file.
I am 99.9% that you don't do maintenance on your hard drive. Random hard drive failures are called random because they can occur at any time for no particular reason. If you want to rule that out simply because it's unlikely I'll apply the same logic to KERNEL_DATA_INPAGE_ERROR: It's unlikely and therefore didn't happen.
Considering it's a SATA II HDD, I'd guess it's pre-2010, max 2011, so it'll probably have 3 (667GB) or 4 platters (500GB). Bonus: 7200rpm. I can definitely think of HDDs that are less likely to fail. You should definitely at least run Chkdsk.
It could also be the RAM. Run memtest86+.
Sidenote: 12GB RAM, possibly 2010 high-end HDD, B75 chipset, GT630 looks a lot like they were just trying to get rid of leftovers from high-end Nehalem systems (the RAM, HDD and maybe PSU (standard 80 PLUs, not even Bronze) and case), got a cheap mobo and GPU and then put an i7 in there to justify a 1000$ price tag. Welcome to the world of pre-builts.
Fair point lol, I'll look into the harddrive possibility. Ty
also yeah I know building your own pc is better both for your wallet and performance, but at the time I really didn't have the knowledge to do so without tons of problems. The local IT store that provided me the PC also gave 2 years warranty and free support forever on all products I bought there. I bought my laptop there too and they've fixed it twice free of charge. Idk, seemed like a fair deal at the time :P.
