Could it be memory module issue? Maybe resit ram and see how.
Thinking back it all seem to start when the PC didn't boot like 1 week+ back.
It was a red light of the DRAM LED on the mobo.
I removed the 2 sticks I mixed in some months back leaving the original 2 sticks.
CMOS reset and the PC boots again.
Then the BSOD nightmare begins.
I cleaned the PC internals, wipe down fans, compress air can everything and resit RAM and gfx card.
SMART data of the storage drives are green.
I did 4 passes of Memtest86 and the 2 original sticks pass with 0 errors.
DDU the gfx driver and reinstall gfx driver (though I do use NVcleanstall as I did for years).
Tried a Win10 repair install but failed.
Just yesterday it dawned on me that perhaps its the ramdisk?
I uninstall Softperfect Ramdisk.
I could play Honkai and Genshin again.
Though Genshin crashed first time when I left it loading to map untouched.
Second time I loaded to map and actively play then it didn't crash.
Installed ramdisk again and Honkai freezes and BSOD started appearing.
I've been using ramdisk for quite some years already though.
Just to save the SSD from the wear of frequent writes of the browser cache (as the net suggest).
Though I remember theres a few times the PC went off when the PCB trip during thunderstorm.
Would that cause corruption?
Maybe I'll try repair install Win10 without ramdisk.
Also read that PSU can cause BSOD too, that I have no tools to test.
So easy to spot a bloated capacitor back then lol.
Back then just eyeball bloated capacitor then go down to SLS and bought this current PC.
EDIT:
Still BSOD without ramdisk, pretty random at this point.
Win10 repair install still same error without ramdisk.
