PC crashes every time i touch the tower, fixes itself when i power it off completely

Every time I even come near the tower, like plugging out a usb cable or accidentally bumping it with my foot, it goes into a black screen, but audio keeps working for a couple seconds before all output dies. Also, the fans keep spinning and all my RGB stays on. Rarely it does this without any contact (maybe dust?)

I have a feeling it's a power issue but i'm not experienced enough to know

Specs:

• Ryzen 5 5600x
• RTX 3070
• 32GB DDR4 3600mhz
• Asrock B550 Extreme 4
• Deepcool LE240 AIO (half sure)
• Fedora Linux 43 (Kernel 6.19.10) or Windows 11 Pro (happens on both)
• Unsure what PSU i've got, it could hold off a Ryzen 3 2200g and RTX 3070 before i upgraded though
