Ok guys I have a problem. I tried moving my tower the other day and ever since when I turn on my computer the display comes on but its all green but i can still see the writing behind the green. Now I'm using a ATI 5450 1gb and HDMI cable going to my 40" HDTV. When I wiggle the HDMI cable it clears up but as soon as I let go of it, it goes right back to the distorted green screen. Any suggestions. Thanks
