Caporegime
RMA'ing the GPU, if it is the GPU, TBH i think it is, might be a pain but at the end of the day if its faulty its faulty, its not going to get better over time and the longer you pontificate over it the older it will get and with that the chances of you getting the best outcome diminish, its why i asked how old it is, usally they don't do a full refund if its more than 6 months old.
