Random pop and digital plops


I am using w7 pro 64, lYNX and UAD, and get digital pops all the time. See attached image.
i have tried disabling Asio guard, reinstalling Cubase, reinstalling Lynx and i get the same issue. In fact the machine was freshly installed in january as well.

i have been down every f**** route now so any creative tests or ideaas would help.

I dont get this issue with eg NI Maschine as standaalone, which should indicate there is something with Cubase
