Question PC boots but no signal to monitor ?


Jan 27, 2016
Hi, I've implemented some new components into my build.
It boots up, every fan spins, every led glows.

The only problem is, monitor keeps switching between HDMI and Analog.
It's like it is unable to decide which signal to take in or doesn't recognize any signal at all coming from the GPU.

Speaker gives no errors.
Monitor was tested with other build and same GPU worked.

New CPU doesn't have integrated graphics, so can't check that way.
It was all clean install of new MOBO, RAM and CPU.

I tried CMOS reset, re-seating RAM cleaning it, dusting off slots, re-seating GPU.. My only bet now is that the PSU might not be enough, even tho' the buld has still same Wattage as the one before.
Also tried only booting with one RAM stick. Nothing. As well as using different and new cables for GPU and monitor.

Please someone help.

New components:
CPU: i5 10400F
RAM: HyperX DDR4 2666MHz, 2x8GB

Remaining ones:
GPU: MSI Armor RX 570 8GB
PSU: 500W Enermax 80PLUS® Bronze certified
HDD: 1TB Seagate
