Question 2 of 4 USBs stopped working

Apr 27, 2020
So today I repasted my laptop and cleaned the fans the same way ive always done it. This time when I rebooted my laptop the two usb ports on 1 side of the laptop stopped working, they worked for a second because my mouse lit up but then stopped. All my other ports are working fine except these two, adjacent ports. Any idea what happened/how to fix it? Hoping it was an error from when windows booted and not a loose cord or something. I dont think it was a cord issue though as everything I did when the pc was open was on the opposite side to the USBs so i wasnt anywhere near them and I was touching the working ones if any. Thank you.
