I always buy refurbished computers because I've found the bugs are usually removed. I purchased my latest computer through Overstock.com, and it was refurbished by Joy Systems who sent me a different computer than what I ordered. Among other problems, it wouldn't boot with anything plugged into the front USB ports, and in less than a year of use, it killed itself. I've tried all the boot suggestions Windows 10 told me to try and it didn't like any of them. I've used computers since DOS and this is the worst one I've ever had. User's recommendation: If you want a refurbished computer, make sure Joy Systems isn't the one doing the refurbishing.
