So I just got my new computer up and running, as of now I am using the built in hdmi out on the motherboard. I installed windows 7 without any problems but for some reason after windows is installed and it fully boots my LCD (lg 37ld450) says there is no signal. This happens after the windows logo disappears and the computer is loading up the windows screen (desktop). I have unplugged and plugged it back from both the tv n computer with no luck. I know it is not my tv %100.
