Small audio clicks in cubase 9.5

Hi, i’m a new user to Cubase 9.5, I have set it up and it seems to be running ok except there are small random clicks output over the audio, this even happens with just one Cubase vst synth running, I have got the latest drivers loaded and everything seems to be synced up ok, I have also tried changing the buffer size all to no avail. I’m running 64bit version on windows 10. Can anyone suggest things I might try to fix this?

I persevered with this, I think the problem was caused by having connections in the “audio connections” that had nothing on the other end, left open ended. When I changed this to “no connection” it stopped the clicks, Not sure why this happens but at least I know how to fix it now.
