Cubase le 8 keeps skipping when I'm trying to record or playback?

Hi I’m new to this and im trying to learn on how to use cubase le 8 more… So ive been having a problem lately where when I try to record a song or do some music and I’m listening to it through the headphone set I can hear that it’s like skipping and before I could just restart it over and it would work but now for some reason it has gotten worst can anyone please help me!?
Is there something I’m not doing right or something I need to add in?

Please list your computer and audio hardware specs, the type of tracks you recorded in your project, and which, if any VSTs you are using.
