Game won't start

after i log in the game crashes. Sometime's it'll get to to the main menu and then when I click start game it'll crash after that. It's always the same Windows message saying that FFXIV stopped working. I just installed the game a few days ago. Does anyone have troubleshooting tips?

System Specs: Microsoft 7 premium Home Edition
Intel Celeron 450@2.20 gHZ
DirectX 11
Intel g45/g43 express chipset family

First off, your CPU is below the minimum requirements, and if your are using the on-board graphics of the chipset, then that too is below the min. req. specs (and should not be able to run the game).

Minimum requirements

So, even if you were to add a discrete video card, due to the single core CPU, you would not be able to run the game satisfactorily.
