Here are some random troubleshooting steps that you might want to take:

Spoiler

- Clear the CMOS by removing the battery for ~10 minutes and then putting it back in.

- Make sure all of the appropriate cables are plugged in; 20/24 pin ATX connector, 4/8 CPU power connector, PCIe power connector(s).

- Try reseating the CPU and try to ensure that it's making good contact with the pins (or holes).

- Try using a screwdriver to jump your motherboard without a case power switch button (Gamers Nexus Guide).

- Buy a POST speaker (if your motherboard doesn't have one) and listen for beep codes (Beep Code Meanings).

- If your motherboard has a POST code display, check your motherboard manual to see what the code means.

- Try using another keyboard and if possible, and plug it into a motherboard USB 2.0 port.

- Try using another CMOS battery (they're usually CR2032).

- Reseat your BIOS chip if possible (this requires tweezers and some patience).

 

- Try using just one stick of RAM in your motherboard and make sure to put it in the appropriate slot (consult motherboard manual for this).

- When seating your RAM modules, make sure to push them in hard enough (newbie mistake).

- Try using different RAM modules (that are 100% functional) from another PC in your new system.

- Verify that your new RAM modules are working by trying them in another system.

 

- If you have an iGPU, remove your dedicated graphics card and plug your display into a motherboard display output.

- Try using another display output on your video card and/or another display cable (that is 100% functional).

- Try reseating the graphics card and/or trying it in another PCIe expansion slot.

- Try using another monitor or display (that is 100% functional).

- Verify that your new graphics card is working by trying it another system.

- Try using another graphics card (that is 100% functional) from another PC in your system.

 

- Reseat all the cables and make sure there are no loose connections.

- Try power cycling your computer by turning on and off several times (Guide).

- Try using another power cable/cord (that is 100% functional).

- If possible, conduct a paperclip test on your PSU (EVGA Guide).

- Make sure the PSU is working by trying it in another system and putting some load onto it.

Try the steps set out here:

I turns on when with my GPU installed, but only if it isn't connected to the PSU. 

How could that be? 

GPU:Gigabyte Rx 570

PSU: Corsair cx550m
