Question : Computer generates annoying chick chick noise at intervals...

This is really annoying. Every so often, I hear this most annoying noise in my computer. It's a very short click but it happens every so many minutes. My other computer does a chick chick noise. When listening to music, this is the most annoying noise.
Is this a virus?

Answer : Computer generates annoying chick chick noise at intervals...

I wouldn't delete the DLL if I were you because of a couple reasons. The first one is you said that the problem started happening before you installed the program so that probably wouldn't be a problem. The second reason is if you delete the DLL, the virtual piano program could stop working. I could recheck your list of DLLs if you want but I think I'll do it a little later.
