So I was watching youtube vids then a big blue screen with no signal appears on my tv, I reboot about 2 times and it does the same thing. I unplugged my gc and used onboard video and so far no more no signals, however onboard graphics give jack shit in terms of gaming performance and forces me to use 720p insted of 1080. My tv is a soniq branded 32 inch lcd and the graphics card is a radeon hd 7950, can anyone help me?
