Well, My Screen type is a ViewSonic VA1912 screen,Also I've tried differn't screens got a friends Acer Screen still Cut Out

So its not the screen.I left my comp un-plugged for like near on 2 days(Didn't count how long :p)then I Tryed differnt types of cords I had the Blue Analog one pluged-in(the one i use)Gave me about enough time to copy 3 parts of Grando Espada

. So I tryed the White Digatal One about 10-15 mins ago then it cut out as soon as I opened up My computer

so..... its not the cord or the screen I think it might be the Graphics card as I've had the computer for about 2-3 yrs so The card might be on the way out

.If it is the graphics card is a GeForce 8800 Graphics card good for a Hevey duty Gamer? Or could You Guys on SRF Recommend a Good Card
Thx.
