while recording, wave form looks broken up

I may be using the wrong terminology here but when I start to record the wave form is broken up.Instead of solid formations they are a group of straight lines.Playback is garbled. Don’t know how else to explain it.Settings look fine ,using WASAPI on win 7. First recording was good. Now garbage.
I’ll be watching for your thoughts,if any. I know the info is vague, i was trying to do a screen shot but couldnt figure it out.
