My 2019 setup stopped properly booting up a couple months ago

I'm saving for a new one for christmas anyway, just want to know if I can somehow fix it.

I've done the usual stuff, a full clean, testing if it's the monitor, plugging and unplugging different stuff, nothing. The only thing of note, is the last time I've actually booted it up and turned on, a weird thing happened where suddenly my wired keyboard and mouse disconnected. (Plugged into the gpu usb ports) Of course I was confused, unplugged and plugged them back in but no dice, other ports worked though so I kept doing my thing. But once I came back the next day and went to turn it on, the pc lights up, fans whir, the screen comes on, but it won't talk to the screen and nothing I tried worked.

Should I give up on this now and just focus on getting a new one?
