Our 9 year old Dell Windows 7 desktop got killed last night in a storm. Since its so old, the plan is a new Windows 10 machine. I think the power supply got fried but the SATA hard drive works. I press the power button and nothing at all happens. I have most recent important files, and a "fairly recent" backup, on an external HD (USB 2.0). Once the new desktop is set up, what I hope to do is migrate some files, and if I can, a couple programs to the new computer. I'm just not sure where to get started. Cost is a factor. I'm retired and my wife had a recent 2.5 month blip in employment. I have a little computer experience, but not a lot. Any thoughts would be appreciated. Thanks.
