Ciao a tutti, mi dispiace aprire un'altro post, ma mi sbuca un errore dopo l'altro!

Questa è la mia configurazione pc:

In soldoni, quando ho provato installare ubuntu con la mia VGA (non ricordo il nome del modello), mi permetteva solo di utilizzare la versione live da usb mentre se lo installavo crashava al momento del login.

Quindi l'ho tolta e ho inserito la spina nella vga integrata della mobo.

Siccome ho speso fin troppi soldi ultimamente, volevo sapere cosa rischio se non utilizzo nessuna vga ma utilizzo quella integrata?
Mi interesserebbe sapere anche come posso risolvere il problema con la VGA attuale?

Grazie a tutti in anticipo
