I accidentally bumped into my PC, and now it won't turn on—everything went off except for the RGB lights. I've already tried reseating the GPU, reinstalling the RAM, and resetting the CMOS battery. What else can I do, or should I just take it to a repair shop?

Is it showing any signs of life, like fan movement or lights? You might want to check if the power button connector has slipped off the motherboard pins.
If you've cleared the CMOS, it might take a little while for the PC to start up again—sometimes it can be 5 to 10 minutes or longer! Does it stay powered, or does it shut off after a few seconds?
Have you checked the CMOS battery? It might need some attention.
I suspect there might be a loose connection from the power supply. Sometimes the bumps can dislodge a connection that wasn't fully seated.
