Computer boots but has no display.

[bekas]

Hello everyone, I just recently bought my first pc (which I assembled with my dad, who has quite some experience in building and repairing PC's). However, whenever I boot it, fans start spinning, everything lights up but no display. I tried booting it without the gpu, but the motherboard returned 1 long beep followed by 2 short ones, which I read was a gpu problem. The problem isn't the monitor or the cable, since I tried them on a different pc and they worked just fine. Also, it booted once and I was able to go to the bios, but when I restarted it, it went back to no display.

Pc specs:
MSI Radeon RX580 Armor OC 8gb
MSI B350M PRO-VDH SKT AM4
AMD Ryzen 5 1600 3.2GHz
Seasonic S12II 520W
WD Blue HDD 1tb
Corsair Vengeance LPX Red CL16 2400MHz (2x4gb) DDR4

You can not boot your system without the gpu. Ryzen doesn't has a integrated gpu. Reseat your gpu and check if your vga cables are plugged in correctly. You can borrow a psu from a local store and see if it works then. Make sure that the card is working in a different computer too. Checked if you plugged hdmi cables into the graphic card. When none of these works rma your card dude.
