Blue screen doesnt sound normal if you use Windows 10, now if its Windows 11 thats a different story.
I dont use codec packages myself since I didnt need them for anything so far.
Games run all like they should and for videos I am using MPV.
Some things that still come to my mind regarding this: you can look in Windows Event Viewer through the error logs, try deactivating firewall/antivirus, you could reinstall your graphics driver (NVIDIA/AMD) so the settings are all default again and you have the newest version and check if windows recently installed some updates, if it did uninstall those updates. You can also decide to run those games that arent working on your computer on a virtual machine like vmware and play them like that.
Maybe you could also share where you downloaded the games from just to make sure that the game files themselves are alright.
Though the easiest thing would be just to reset your Windows pc to factory settings.
Just backup all your data before on some external device like personal files, media files, bookmarks, logins, installed programs and so on.
Remember dont trust windows with keeping your files.
After the reset set up all your settings (like changing unicode to japanese for eroge), install Macrium Reflect Free, make an image of your drive and you wont have any issues in the future (since you can just roll it back in like 10 minutes whenever somethings not working, before that of course always save your personal files) with the exception if your pc decides to die of course. One way or another, this all faded into the background, because I was seriously puzzled by my academic performance. And now I'm working to improve it and this service has become a godsend for me
