Please help! "Game.exe has stopped working" for every game!

[ScaredyCatCally]

Hi, I brought my pc (Fierce PC) two or so months ago. Everything was working fine and I could play every game I downloaded (Amnesia, Witcher 2 etc.), now I can't play anything without it crashing with "game.exe has stopped working". It's really annoying me as I can't play my games and I need to for YouTube. It only started happening two days ago as I noticed it when I tried to play White Day (which I downloaded from ModDB) and I thought it might just be White Day, but then it happened with The Midnight Game. Both got the message as soon as I selected start game. Then it happened with Amnesia when I played the Dark Room 2 custom story. It happened when I progressed further into the story, and then started happening at the very beginning as I tried and tried again. Then I got an error log for Amnesia. Here's the HP Login.

Thanks. I'll try that tomorrow. Is that something that'll just work for Amnesia or will it help me find out what's happened to my computer for all games to stop working?

If it's universal, why not try a system restore to before when you had problems.
