Hi everybody...I have a Gigabyte G1 Gaming RX 480.My HDMI cable isn't the best and it doesn't fit well so I can say that I don't have a good Monitor-GPU connection...I Had a Blue Screen of Death Earlier My PC shut down and when I opened it it booted correctly and then I changed the voltages in wattman like always do and every time works very stable ...But this time when I did it my screen went full of pixles and flashing images then it went black and pixles again and then black again etc...PC shutdown and then I got this screen that said that its repairing my C: Drive..After that I changed again the voltages and ran the Furmark Benchmark ...it was stable.I didn't see any artifacts or pixels or anything and it is stable til now..I ran the test 3 times or so.I have t mention that this pixel thing actually happened when I changed the voltages and after I opened the Gigabyte Xtreme programs which didn't recognise my card...Do you thing its dead ? My GPU is like 2 weeks new ...Should I do something else?I ve gone through so much pain t get it working properly..I changed PSU etc.I'd appreciate every answer.Thanks is advance
