Default Computer stopped recognising USB devices

Hey guys.

I was testing a power supply unit and decided to do so in my working computer. All went well until I replugged everything back into the working computer. Suddenly, USB devices in the USB ports were randomly failing to install.

There are 4 USB ports at the back and 2 at the front. Initially I could only get the mouse to work in the back (keyboard only worked at BIOS; didn't work in Windows). Then, the mouse stopped working. If I plug them into the front ports they work fine. If I try the back, they come up with error messages saying "Not recognised" or "Not enough power" or "Couldn't install". The weird thing is, they used to work in the back fine. Now, its a no go.

I have triple checked that all the cords are plugged back in their appropriate places. Does anyone have any ideas as to what is causing this problem?

I would guess your PSU is under performing. That is the only thing you changed, correct? That may be the culprit.
