PLEASE READ ALL SO I DONT HAVE TO RETYPE WHAT I ALREADY SAID
I recently built my computer and everything was running fine the first night im actually using it right now to wright this,but im on my onboard video. i installed quake 4 and still everything was fine my gpu took it fine. So the next day i went out and bought battlefield 2 and installed it and when i tried playing it everything started to get distorted and so i took it out. Now ever since then my graphics card has not been working right please help ill list everything i think is needed. Oh yeah i have downloaded the newest bios for my computer and i have uninstalled and reinstalled the drivers for the card, but it runs slightly better without the drivers. I am also using the newest driver.
My problem i am getting distorted images and pixelation. My computer runs extremely slow when plugged into it. My monitor blinks when plugged into it. I have all power supply plugs into it so its getting enough power.
