Ok i just receive my parts and im watching the newegg how to build a pc tutorial. i have an Asus revolution mobo and an i5 2500k cpu, i put most of it together outside the case as instructed in video the went to do a post start up test. According to video i should have receive an Asus test message confirming all components are working properly. So i power up and everything seems good ( fans,lights ect )... But no Asus screen message. Any ideas why?
