PC peripherals not working

[A Google]

The other day I opened up my pc to install a new hard drive. I hadn’t succeeded at installing my hard drive but besides that, everything went decently well, except that I had to push a few extra psu cables around. When I turned my pc back on, every component turned on normally. My gpu and mobo lit up I heard the hard drive and gpu fans. However, my my monitor, keyboard and mouse did not. I put my pc off and I turned it back on a day later and it booted up normally and displayed my desktop page on the monitor.

Then I noticed I hadn’t installed my hard drive properly. I opened my pc up again and searched for the right cable to plug into my hard drive. It seemed to have worked, but my peripherals weren’t turning on again. I checked the next day and they still weren’t turning on. Then I reseated my gpu and switched the pcie power cables and removed the pcie extedner (since I thought one of the wires were damaged or missing) and swapped it for another cable but it still didn’t work. Help?

Have someone with you check over your wiring in the system.
