If this is intended to be a request for help rather than a rant, you might want to tell us a bit about your hardware and what version of PCLOS you are running or trying to run.
Also, have you installed it or is this happening with the liveCD. Also, at what point do you see this?
I could think of a few answers if I knew enough to narrow down which one would apply to your situation.
For instance, some combinations of BIOS settings and hardware will not recognize a USB mouse while accessing the GRUB menu.
