A75m-itx hdmi problem! HELP NOW

[solitarypredator]

Hello guys. I got an a75m-itx and A8 3870k hooked up with an lg 42" lcd tv. Sometimes when i boot i get a "no signal" message on the tv. And i have to reboot to recive the signal.
Is my motherboard broken or is it a "handshake" problem?
Also which drivers should i use to the internal grapichs? Thanks guys!
