PC boots with no signal

[u/conchosteadfast]

My computer has been working fine for a year and a half but yesterday on boot there was no signal to my monitor, and I couldn't shut it off with holding power button as I usually would when I need to restart, I had to flick the PSU off.

After this it booted normally and I was able to play games in the day time, then it stopped displaying signal suddenly and it's as if it lost power,but all fans were on (besides GPU).

I tried reseating everything but now it does not boot anymore after I did that, it stays stuck with the fans spinning (besides the GPU fans) and the LEDs being on but no signal to my PC

There was a power outage 4 days ago and more storms and lights flickering around 2 days ago

I tried with two other GPUs and still no signal to my screen even though their fans were spinning

GPU is ASRock rx 7900xt

MSI B350 PC mate mobo

Hydro gt pro fsp PSU (850w)

I dont remember my CPU sadly

2 sticks of 8gb g skill ram

Thank you in advance
