It seems that no matter what gives me a static discharge in my room, it turns my PC on. For example, I often get a static discharge from my chair, and my PC turns on. Same thing if I touch my laptop, PC turns on. What causes it and how could I prevent it?

Your PC always has power as long as the power cable is connected. When it is powered off, the internal components just don’t route that power through anything that actually does something.
When you press the Power button, it closes an electrical circuit that tells the PC to start routing the power to all the other components, which then starts the boot-up process.
The internals of your PC are supposed to be electrically insulated from the environment, but if this is no longer the case it’s possible that the static discharge is somehow inducing a sufficient electrical charge in the Power-on circuit to make the PC think that the button has been pressed to close the circuit.
Things you can do to possibly prevent it includes making sure that the internals of the PC are clean (use compressed air to blow away dust) and free of debris, that the insulation on the wires connecting the motherboard to the buttons in the casing is not damaged, and that there is no damage in general to the internal components.
