I just finished building my new PC, but when I turn it on, my monitor shows 'Displayport no signal.' I've already tried connecting an HDMI cable both to the GPU and the motherboard, but nothing seems to work. Here are my specs: CPU - AMD Ryzen 7 9800X3D, Motherboard: MSI MAG X870 Tomahawk WIFI, GPU: ASUS TUF RTX 3070ti. What could be causing this issue?

Make sure your monitor is set to the correct input. If you plugged in an HDMI cable and it didn't switch automatically, you might need to manually set it to HDMI. Also, what error light does your motherboard show? You mentioned seeing a green light with code 01 when trying to enter BIOS.
How long did you wait after powering it on? Sometimes AM5 motherboards can take a few minutes to boot up. Also, check if your motherboard has a QLED troubleshooting feature or a readout for error codes—those can help identify the problem.
