HELP!! COMPUTER RESTARTS AFTER SIMS GAME CRASHED!! [SOLVED]

Ok. A day after installing Supernatural, I was playing my game for a while and all of a sudden my game froze. So i pressed the windows key to exit after being on the Screen for more than 5 minute and then force closed it using ctrl alt delete.
I went to turn off my computer and then my computer automatically restarted itself.

I thought that i might have pressed the wrong button.
So i forced turned it off but it did the same thing.
This processed continued until i finally got fed up and took the battery out and it finally stopped doing it.

I am freaked out now and want to uninstall Supernatural and Just Buy it.
Do i have to uninstall all my games since i apply the fix to all my expansions and the main game?

What should i do?

Hello,

Try step 6, please: https://games4theworld.forumotion.com/t4692-game-lag-possible-fixes

There's no difference in buying the game, as it's not caused by the fact that you used a downloaded version, not in any way.

Thank you Admin but i already know about that.
What i am saying is that my Computer wont shut down.

Everytime i try to shut it down since the game crashed it just restarts.
My computer works fine but it wont shut down.

Do you think i have a Virus?

//EDIT

Disregard this message Oh Guru of Computer wisdom.
Turned out i needed to Update and Flash my Bios.

Everything is Fix now.
Thank you.

Hello there,

Wow, hadn't though of that. Flash your BIOS?
Be careful when doing that though, it can mess up your PC badly, if not done correctly.

Anyhow, glad to hear it works now! I've learned another lesson!
Enjoy the game and please do let us know if you run into any more problems!
