Question Just set up PC, nothing appearing on monitor

[reubeng18]

I just put a new graphics card (RX 580) and power supply (URANO VX 650W Bronze) into my pc, turn it on, and nothing appears on the monitor. I have no idea what to do.

Just got a new GPU (RX 580) and PSU (URANO VX 650W Bronze). I turn the PC on, everything boots up, and then the GPU stops immediately (in the space of a second, literally), and the monitor stays blank (black).
I have the Radeon driver already installed.
Any help would be much appreciated.

CPU: Ryzen 5 2400G
GPU: Radeon RX 580
MoBo: B450M PRO-M2
PSU: URANO VX 650W Bronze
Storage: 1TB HDD, 120GB SSD

take the rx 580 out and test with the apu only

I did that and everything else works fine.

when you put the rx 580 in, did you change the monitor to connect to the gpu?
got another psu for testing?

i dont need to connect the monitor directly to the GPU do i? but rather through the motherboard.
In any case, my monitor only uses VGA (big rip), and the RX 580 does not have a VGA port
and as for the PSU, the reason i bought a new one is because my old one, strangely, did not have a graphics card cable.

yes you need to plug the monitor to the gpu to use the gpu

ok, but does that explain the GPU turning on then immediately off?
