Screen turns off when starting the game

Hi,

I have an issue with my game. Whenever I try to start up my sims 3 game my screen turns off.
It's not just a black screen, the whole monitor goes in standby. I really don't know what to do, this problem showed up out of nowhere and I can't seem to fix it. 
The game itself is working because I can hear the music. I already tried reinstalling my base game, removing my downloads, but nothing works. 
Any advice?  Thanks

Hello,

So you are running the game without any Mods or Custom Content?  And you visited this thread and followed all of the steps as accurately as possible?

If you've applied the manual patch and the ultimate fix, tested the game without any Mods or CC, I'd advise you to go to:  My Documents/Electronic Arts/The Sims 3 and make a copy of 'The Sims 3' folder.  You can do this by right-clicking on the folder, copying it, then going to your desktop and pasting.  'The Sims 3' folder should show up on your desktop and this is where your saved games will be backed up.

You can now safely delete the 'The Sims 3' folder you have in your documents.  Once you delete it (again, keep the backup one on your desktop), boot up your game and test it out.  When you boot up your game, it automatically creates a brand new 'The Sims 3' folder within My Documents/Electronic Arts/.  

Running your game on a brand new folder sometimes will help.
If it doesn't, it may be that you need to apply the manual patch and ultimate fix again (see the link I posted above).  If THAT doesn't work, it may be a hardware or graphical issue... in other words, it may be your PC.

Let us know how it goes.

Happy Simming 

Seems like I had no graphics driver on my pc   Don't know when that happened. I fixed it but now there's a new problem. I need to update my game (because I reinstalled the base game) so I downloaded the ultimate fix and just did this step:

10. For The Sims 3 – Into the Future &Movie Stuff &Island Paradise & University Life & 70s, 80s and
90s Stuff & Seasons & Supernatural & Diesel Stuff & Katy Perry’s Sweet Treats & Showtime &
Master Suite Stuff & Pets & Town Life Stuff & Generations: open the "All expansion packs released
after and including Generations" folder in this .rar file and drag & drop both files in there to:
C:\Program Files (x86)\Electronic Arts\The Sims 3\Game\Bin (SO NOT TO THE EXPANSION’S GAME

Now my launcher crashes when I try to open it. Oh well. Trying the manual patch now, hopefully that works :p

EDIT: It worked, game is up to date, latest driver is installed... But the problem with the screen is still there :'(

Same thing happens when I start up Sims 2. Seems like something is wrong with my hardware like you said

Then I am afraid you might want hardware replacement, or want to build a new pc, or buy a new computer/call a technician to check the problem.

Before you do that though, please make sure all of your graphic drivers are up-to-date. To do so,

Go to Control Panel >> System and Security>> System >> Device manager.
Expand the tab "Display Adapter". If you can see something below it, right-click it and choose "Update Driver Software".
If that doesn't help go to your corresponding graphic card site and download a suitable graphic driver software for you.

However, like Carlos said, it might have something to do with your hardware.

The driver was also up to date. Buying a new pc is not necessary I hope. I'm buying a new graphic card. Hopefully it will work. Thanks for your help!!
