Hello,
A friend of mine was having some weird lines and other artifacts on his screen. I suspected that something was wrong with his gfx. I've put it in my pc to check and I've got the exact same artifacts on my screen with it. While I think the card is dead, I certainly won't ignore the opinions of the more experienced people out here . I'll post some screenshots below. http://imgur.com/LtC5eFI&YPTX3f2&cmFT2A3&HzhfgaB#0
Thanks!
