Hey guys I got a intel i5 2400, gigabyte mini mobo, 8gb ram. First off I bought a r9 380, installed it, worked great ran plenty of games at max. Then my computer turned off and started telling my monitor I had no signal. I wasn't able to get into windows computer would just keep restarting.. I installed new windows and same issue still. I figured the card was faulty... went out and bought a gtx 770.. installed it everything seemed fine and then I tried running a game and I have the sameness issues as before however now there's green lines all over the screen.. please tel me I didn't fry two GPUs.. I don't know what's the issue is my power supply is 850 watt I even bought a new psu tr2 and it's still giving me the same issue when I try this GPU.. what's going on guys? I can boot into safe mode but again geeen lines all over the screen. My bios aren't up to date
