I have a Asus Desktop. And a 30" Emerson tv. An have an ATI Radeon 5770 with a TR2 600W. And my problem is when I plug the HDMI cable into computer an the Tv. An turn computer on for like 5-15min of being on it. My screen will go black. No cursor or anything. But the computer is still on and so is my keyboard and mouse. Don't know what the problem is. ( will take picture of inside if needed.) Please help if know anything about this.
