My home built computer isn't turning on

After use for about 3 months I moved my pc and it suddenly won't turn on. I'm not really sure where to start.

I had a similar issue, and it was the power supply. If you dont have a high end (seasonic, corsair, etc.), it is highly likely to be that. When you push the button, if no fans/drives/lights turn on, it is almost definitely your power supply.
