Hi karelgeorge!
Okay as you are playing on a low spec pc, let's try following workaround:
At first, please check your latest video-card driver and check what version of the origin client is installed on your computer. Install the newest driver for your video card.
Go to your custom settings of your video-card software. Disable all extra options for enhanced graphics and set the preferences for AA and anisotropic to “use application settings”.
Set the DS3 graphic options to “low quality” or choose "custom" in the graphic menu and disable all graphic features.
Launch the game, if the issue is solved, you can try to set the graphic options higher, just step by step.
Get sure that you disabled/closed all not needed software beside the gameclient.
Sometimes, this issue can be related to the cloud storage.
Open your Origin client, click on “Show Game Details”. Then you go to the cloud button on BF3 and uncheck the “enable cloud storage for all games” box. Launch the game.
If that helped, you can try to enable the cloud storage after a restart; it might work after with the cloud storage function. Make sure to use the local data when the information box popping up.
Cheers
Basti
