My Microsoft had computer will not reboot. This started

Customer Question

My Microsoft had computer will not reboot. This started after our electrics blew a couple of days ago. We get a blank screen with a grey line which goes to blue for about a third of the way and then stops dead.
Thank you for any advice.

It is the internal motherboard that has faulted. Everything else has been ruled out. It will have a blown capacitor from the outage as the most likely cause

I am really sorry about this and you are going to have to return the computer to have this replaced.
