I would recommend to repair your install first. Open your Origin client, go to your Games Library and rightclick on the PvZ:GW icon. Choose "Repair Install" to check if this issue is related to some corrupted data.
Update your Direct X, video-card drivers, your soundcard driver (especially if you use a Realthek HD card) and Microsoft .NET framwork.
Please try the following workarounds and keep us updated:
- Update DirectX as well as Microsoft .NET framework
- Run as administrator (for PvZ and Origin).
- Microsoft Visual C++ x64 and x86 versions of 2010 and 2012 uninstall. Reinstall with Visual C++ Redistributable for Visual Studio 2012 Update 3
- Update your videocard driver and clean boot your operation system
