What OS are you running? You have a balanced selection of components. Are your temps. ok? What exactly is happening when you say crashes? Is it going bsd, freeze up or restart/shutdown? Have you installed any new software recently? Have you upgraded the bios, drivers or anything else? You may have a software conflict. Please provide more details.
