These people keep calling, they should be stopped as its part of a scam to make you think that your computer is faulty. They say that Windows warranty has expired and that it needs to be renewed to fix the problem - that they keep seeing error messages coming through to their service centre. They then apparently charge you to update your warranty, when there is really no issue with your computer
