Hi there, I'm Tim and will be assisting you today. I have over 15 Years as an Engineer and have been with eBay, DoD and many others. I will do my VERY BEST to help you. If you like i can offer remote access and a call. In addition, with any positive rating I will support your question going forward for free.
i'm not sure about your service contract, i'm sure i can point you in the right direction. As far as windows 10, i'm personally not recommending it for about another 60 months as it is very buggy and has caused many people problems.
can you tell me the specs of your PC? or make and model?
