Mouse and keyboard not working

[Corals]

My mouse has been freezing for the past couple of weeks, but it would come back to life after when I restart the computer. Yesterday, it decided that it was not going to come back to life and froze completely.

I thought maybe the mouse had died so I bought a new one. Same thing, the mouse does not move. The end of the mouse which plugs into the computer is rectangular shaped and came with a round extention. In the beginning I had plugged it into the computer using the round end.

I decided to take the extension off and plug it in using the rectangular shaped end. I thought, Bingo, it works, but when I went to type in my password the keyboard is dead, nothing appears on the screen when I type.

I am thinking, is it the sockets for the mouse and the keyboard that are not working, as they are both next to each other?

Can someone please help before I take the computer to get it fix incase it is a slight problem.

Thanks.
