Hello and welcome to PCHelpForum.

Firstly I have marked your thread as "Open" in readiness for our great Tech Team and wonderfully helpfull members to help you.

Is the TV recognized in windows display and have you tried to configure via NVIDIA control panel advanced options?

in the windows display it comes up as plug in play monitor and i can only get it to run in safe mode im so clueless as to wat to do and thank you for welcoming me into this forum i am very good with computors but this is confusing

ok so i broke down and bought a dvi to hdmi cable i got my picture back everything is fine except one thing whenever i watch a video or start oneof my games the screen has a checkerboard pattern all over it what is going on is my video card done or wat

Mmmmm maybe you need to check your temps?

When was the last time you cleaned inside your computer?

Is the cooler spinning on the graphics card?

Could you go to your "User CP" and fill out your computer specs and check box show others as this may help in getting you a fix.

Download and run this:SpeedFan - Access temperature sensor in your computer lets check your temps of this card.

ok so i filled out the computor specs chrt thing in user sp i did check the temps they seemed fine i am wondering tho y does this only happen when i play high quality video or full screen video orrrr if i start a game like wow or wat not this is rally weird

It could be your graphics card.I think it is realy not suitable for very high ended games and gets a little hot at times or just cannot handle the game play.
