Chase Essential4 VST performance

I have recently noticed that as I am trying to record or playback tracks the Disk column on the VST meter fills in completely and a red light comes on at the end. The track audio then cuts out and then jumps back in again.
When this happens the track continues to scroll, but there’s no audio. After a few seconds the light goes out and the meter returns to normal… But then it happens again. Can anyone help as to what is causing it? The PC is quite new although I’ve had the software while.
Many thanks.
