After cleaning the pc and unplugging and replugging the cables, the pc wont boot. At first, it powered on for half a second, than it turned off. Was working fine a few minutes ago

Edit:

PSU is now humming when plugged in

Also have warranty for all the parts

Ensure every connection on your mobo was not wiggled loose. If your front IO connectors came unplugged or something, you might have an issue.

The power supply hummed? What kind of hum. Can you maybe try to describe it? That isn't really ever suppose to happen. PSUs are suppose to be nearly silent. 

I am suspecting your power supply has failed.

I feel like an armchair electrician, but I think that your PSU may have failed. Considering it still won't boot, something must have borked it. I think it would be best to recheck your motherboard connections.

A turd with an HDMI cable jammed into it is more powerful than a MacBook Air, and up until this year it had a better display, too.
