alright so
basically i got a new computer, connected the DVI cable and hooked my nVidia GeForce 7900 GT up all nice
booted the computer and the screen was fat and the normal windows 7 windows were coloured not clear
i installed latest driver for it and then rebooted
upon the reboot i got to the login screen and logged in, once logged in the screen was instantly covered in dark blue and red lines
followed by lines of different shades of blue
safe mode worked fine so i went into it rolled back the drivers
booted in normal mode and all seemed to be working, i went into Left for Dead 2 and there were constant shapes and colours everywhere that werent supposed to be there
i exited and tried a different game, Magicka, to see if it was just L4D2 but i opened the game and those blue lines came back
i have a suspicion that the video card is bummed or the video RAM
can anyone help?

Try reseating the card and if that doesn't work your video card is shot.

How much do you want to spend on the graphics card, what is the wattage of your power supply, what is the size of your case like mid-atx etc and what do you use the computer for?

Well...if your onboard video doesn't present the same/similar problems...I'd say there's only one direction in which to look.

Assuming that you installed the correct set of video drivers the first time.

Whats on the side of the power supply should be a white sticker or label with the wattage information.
