Asrock x370 taichi no boot

Hey guys... I recently bought these parts a ryzen 7 processor, an asrock x370 taichi, corsair vengeace LED 4DDR-3000 (2 * 8 gb), a Seasonic 350 W 80+ bronce certified,  a samsung 850 evo series 500 gb ssd, an msi 1070 gtx ge force 8g graphic card and a NEXT s340atx mid tower. I currently cant boot to BIOS (no display signal whatsoever). All the power supplies (to gpu and motherboard are on) , everything is plugged in correctly, I have tried to change the location of my ram with no avail, I have tried taking the battery out, the gpu out. Nothing seems to help, I checked that the motherboard and cpu work well together (they do checked asrocks page). Im not sure what else could be wrong. Fans turn on (incluing gpu fans), and leds keep flashing (no error code on the 7 segment), there is a beeping noice (constant ). What else can I possible do? Its my first build and it has been a terrible experience :(. Someone save me.

A first build is always the most difficult, and you have not chosen an easy system (Ryzen) for a first build. We will need to check everything. New builders think they have everything right, but it is very common to make mistakes. We have seen that many, many times. As said above, your PSU is inadequate for your video card, the specifications state a minimum of a 500W PSU:

We need the full model name/number of the PSU to determine if it is even adequate to basically run the PC under low load conditions. If it is really a 350W PSU, it will never be able to power the GPU while gaming, sorry to say. The PSU might be the main problem.

You said you have a constant beep sound from the PC. Do you have a POST beep speaker connected to the POST speaker header, in the middle at the bottom of the board? This header is not the System Panel header, where the power and reset buttons, and power and HDD LED connections are made.

If you do, a constant beep from the board indicates a basic connection problem of some kind, could be many different things. Including bent pins on the CPU, memory or GPU not fully seated in the slots, or power cable connection mistakes.

If you don't have a POST beep speaker connected to that header (top row of two pins) then the constant beep could be coming from the GPU.

If you get nothing on the Dr Debug display, the board could not even begin the POST process, so there is at least one very basic thing that is wrong. The CPU fits correctly in the socket only one way, but can be put in wrong and seem to fit, unfortunately. If none of the power cable, memory, and GPU connections are wrong, then you'll eventually need to check that. Although we are still not 100% certain yet what is the source of the beep sound.

First, power to the board. Both the 24 pin ATX and 4/8 pin CPU power cable must be connected to the CPU and board, or they will not work.

Next, both the 6 pin and 8 pin power connectors/cables from the PSU must be connected to the GPU. The GPU must be in the top PCIe x16 slot. Check that the GPU is fully seated in the slot, and the locking clip on the slot is closed.

Also, you must be certain that the power cables from the PSU are the correct ones for the CPU power connector, and GPU power connections. The two cannot be interchanged, they have different polarities.

Memory must be in the A2 and B2 slots. Check that the memory is fully seated in the slot. Look at the edge of the memory slot as a reference line, to check if the memory is fully seated in the slot from one end to the other.

The flashing LEDs, which are probably around the white and black chipset heatsink in the lower right area of the board, are just the RGB LEDs, set to go on and off, or "breath" by default. That's a basic feature of your board. They do not indicate anything, they are just for appearance.
