Ok well give this a try unplug everything from your computer even the power, once thats done press the power button to drain the charge. now remove the Graphics card and you might as well pull the HDD as well just for good measure. now connect only the things you need power mouse keyboard and plug the TV into on board VGA. double check that your TV is on the proper input typically listed as PC (if you want to be really through unplug the TV and everything connected to it wait 5 min then plug the VGA and power back into it) now power everything back up and see what you get.
