Items on my desktop keep renaming themselves.

Ok so I'm really new to macs and have been enjoying it so far. But, I have a little problem. Items on my desktop keep renaming themselves. I already tired to google this to find out what was going on but couldn't find any answers. Keep in mind I am the only one who ever has touched this laptop and I myself didn't rename these items. This so far has happened to my hard drive and a folder on my desktop. Can anyone tell me what's going on?

My DH has no trouble at all accidently selecting and renaming odd items on the desktop of my MacBook Pro. Sensitive Trackpad and tap to click often works when not expected or even noticed.
