Hey Everyone,

About a month ago I added in a RX480 to my current PC. Since then I’ve been having a problem where everytime I turn the PC on the monitors output no signal. Occasionally it boots properly with output to monitors. When it is on everything works perfectly fine. Before I added the GPU I didn’t have this issue. (Was using integrated graphics before)

Specs:
CPU: Ryzen 3 2200G
MB: Gigabyte AX370M-DS3H
RAM: 8GB
PSU: 650W Gold EVGA
GPU: Sapphire RX480-8GB Nitro

When you turn the machine on, but have no signal, does it seem like the machine is actually booting up?

Possibilities I can think of in the order I would suspect
1 - Power supply is flaky
2- Video cable is flaky
- Can you try a different cable
- Can you try a different port ( HDMI->DisplayPort)
3 - The card is flaky

Apparently the PSU does not have enough juice at boot up or is dying.

Replace HDD with SSD if you have any?

Besides, did you plug in the 8 pin power for the GPU?

And how old is your PSU? Also did you try to contact Sapphire ?
