    Do you mean a secondary monitor in the form of a TV or do you mean your primary monitor?

    If primary, most likely it's your fake PSU. Thermaltake makes the M750W, Coolermaster makes a G750m. If yours is the G750m, it's a second rate CWT unit. Replacing it with a EVGA G2 650 or Corsair RM650x is a good idea (you can get away with 550W versions if you don't go crazy on the overclocks and internal lighting)

    Sorry it is the g750m (https://www.pccasegear.com/products/33274/coolermaster-g750m-750w-modular-bronze-power-supply/) and it is the primary monitor i cant afford to upgrade because i just bought all of the parts i have had them for a week any ideas
  3. All of the lights on the motherboard, cpu cooler, cpu and case fans work if that is any help

    Fans don't mean much. I didn't ask before because I would assume everyone is smart enough to do it, but did you make sure to connect the HDMI to the GPU itself and not the motherboard?

    Try running the computer without the GPU (and plug the HDMI directly into the motherboard), if that starts up just fine then it's either the GPU or PSU, and my money is on the PSU

    Of course it won't work without the CPU!!! Try without the GPU (1070), and make sure you plug the TV into the motherboard

    yes i meant GPU it was an autocorrect but it still doesn't work

    In that case the likely culprit is the power supply. Some of the lower tier stuff can't handle the high transients that are associated with modern, power efficient components
