Before i start here are my system specs:
Cpu: i5 2500k
Graphics card: gtx 670
Power supply: 600w corsair
Motherboard: z68p-ds3

Ok so ysterday i got a third monitor and i set it up and plugged it in but when i turned my pc on my computer did not display anything to my monitors. So i unpluged each monitor and tried them individaly as 2 had been working before and nothing displayed. So i tried one monitor in safe mode and i still got nothing so i unpluged my card and put it back in and now my system won't turn on. I have no clue what could cause it so i thought i would ask on here.
