I have had a problem almost a year, My G750JX (GTX 770M Non 3D Screen) Always flicker after like playing a heavy game for about 10 seconds or something like that if i have stock Settings for GPU, i have to underclock to like -22 core clock and -200 memory clock to make it stable ant not flicker and/or crash the pc, weird.... What do i do i can't take this **** anymore im pissed. Making the PC slower than it was built for. Help me!
