4.5 yr old PC acting up- power button flashes when i hold it down to turn it off, screen freezes when pc is bumped lightly, and now my monitor won't turn on
specs
cpu: ryzen 7 5800x
gpu: geforce rtx 3070 ti
motherboard: x570 aorus elite wifi
16gb ram
i don't remember what my ssd is
basically the title. i would give all of my specs, but as you can see, my monitor won't turn on. i tried making sure everything was plugged in properly, and then when i went to try and turn it back on afterward, my monitor just... didn't light up. at all.
is there anything i can do to force it back on so i can try and figure out what's going on?
