Hi, I own a DELL XPS 8700. My (three) screen(s) show(s) red lines. I ran a full diagnostics test and received the following  error code : 2000-0332 . Validation 75318. Video memory integrity test discrepancy. My graphics card is  a AMD Radeon R9 270 2GB GDDR5. I suppose I need a new card but is this card still available and where can I buy it? Or exist there alternatives? Luc
