Re: Sims 3 won't launch on new laptop!
@Kambuchas Are you using Origin or the newer EA Desktop App? The reason I ask is that there's an error related to EA Desktop in your dxdiag, and although I don't think it should make a difference if you can get the launcher to open, it's helpful to know either way.
As a test, please try bypassing the launcher. Make sure Origin or the Desktop App is completely closed, as in, go through the Task Manager's background processes list and shut down anything associated with either one (you'd recognize the icons). Open the Bin folder inside your install location, which would be here by default:
Program Files (x86)\Origin Games\The Sims 3\Game\Bin
Rename these files, in order:
Sims3Launcher.exe -> Sims3Launcher_old.exe
TS3.exe -> Sims3Launcher.exe
TS3W.exe -> TS3.exe
When you launch through Origin, you'll see the splash screen if the game is able to launch. Let me know whether it works.
