Help Please!

I am looking for recommended Computer Repair Shops in the Canton of Vaud; if any are located in the area between Lausanne and Montreux then that would be really convenient. However, I am willing to travel anywhere to get my computer fixed! My machine is a DELL, if that helps.

Can any of you recommend a person or place that I can contact regarding computer repairs in Vaud?

How about knowing any experts who know how to retrieve data from a failed hard drive?
