The power suply in our computer is gone broken. We have brought the computer then to the Computer-Rettungswagen and the engineers exchanged the power suply. I could take the pc the next day again. I call this sometimes quick, would take there my PC over and over again there.
Our family computer always cheeped with the turning on, we could not understand whats going on.. After a short conversation with the engineers they advised me to bring the PC in the service centre. They said to me, they have to analyse the problem. The engineers called me after only one day and I could fetch the PC.
