To start with, I am so angry it isn't funny. I have a all in one dell computer. The warranty ran out which I am aware of. Today, January 24, 2018 I ran a Dell check up on the computer to make sure everything was up todate and working correctly. An hour later I return and the computer won't start. I call Dell and after a while they believe it's the mother board. I tell them everything was working great until I ran their check up. So in the end, it will cost me around 359.00 bucks to replace the mother board. I some years ago we had an expensive lap top from dell, after the warranty ran out the mother board went. Over the years we have purchased a number of Dell computers, but this one is the last. I am so angry with Dell over this. I certainly will not recommend Dell to anyone. Houston, British Columbia.
