Aiuto iMac 27" si spegne da solo!

[J Ax]

Salve, ho un problema con im mio iMac Metà 2010
durante l'utilizzo a volte subito, a volte dopo parecchio tempo, in modo comunque molto frequente dice "il mac si sta riavviando a causa di un errore" e la stessa cosa avviene su windows 8 da bootcamp, ho anche riformattato l'hd e ripristinato osx da bootcamp e reinstallato windows da 0, ma il problema persiste
recentemente ho collegato un secondo schermo, e installato 2 nuove schede RAM (che pero' rientravano nella tipologia consigliata sul sito apple) non vorrei il problema dipendesse da questo..
quando riparte mi da questo:

Hai provato a fare un format totale, senza ripristino?

Inoltre hai provato a rimuovere le nuove ram installate?
