Echoing the other user; I just worked on a data recovery job with your symptoms near identical. Back up your important files while you still have them and get new ones ASAP; preferably some form of SSD.
This is hardware failure, not driver error. Your files will start to corrupt if you wait too long.
When you’re done with your first playthrough, get Revision and The Nameless Mod.
I believe Revision is available on steam but if not, both are on ModDB.
Also, don’t be afraid to explore, learn your play style (it’s meant to be stealth heavy but run-and-gun is also an option), and don’t sink all your skill points into swimming lmao.
The tutorial (“training” option in the main menu) is pretty fun and will get you familiarized with all your basics and tips pretty nicely.
I may have strong nostalgia glasses on but the mechanics still hold up really well and it’s still one of my favorites of all time. I have it on at least 3 platforms and regularly gift it to friends/family when it’s on sale.
I’ve played some of the 4th game but it’s not the same feel really, more akin to Watchdogs ime. The second game got review bombed on release but seems like a decent game from what I’ve heard from other fans. I have it but haven’t played it yet, probably should lol.
Thanks for reading my text wall 😅 /gen
