Boot led on and no display on moniter

[Tauheed]

Ok so my specs are

Gtx 1050 ti 4gb

Msi b350m pro vdh mobo

Ballistix sport lt 8gb 2x4 ram

246 gb silicon power ssd

Thermal take smart 500w power supply

Ryzen 3 1200

Cooler master masterbox lite 3.1 case.

Oh and when i press the power button and everything turns on the vga led turns on for 2 secs then turns off and the boot led turns on.ok so i just built my first pc and it turns on and every thing is working,all thr fans are spinning but when i connect my pc to the moniter using vga,dvi or hdmi the moniter just tells me there is no signal.i have tried using only one stick of ram,removing gpu and my ssd but the problem remains the same and the boot led remains on.
