Hello, I have this problem 2 days so far. But it is very annoying and "harmful". When I connect to Skype (when my all contacts are being shown), a computer suddenly stops working (I mean all programs are so lagged that nothing can be done) and when I turn off Skype, all programs are working properly again... Please suggest ALL the available options which could fix this problem. Please. P.S. Useless answers : "restart Windows" and "Re-install Skype". Thank you.
