Many hours were spent and a lot of different hardware changes were attempted to fix computer. However windows would not update with any of them. I purchased the computer used from them two years ago and only used it three times. Never put any programs or data on it and sure glad I didn’t. I was not charged for the many hours of work to try to determine problem which I appreciate and felt fair since I purchased from them and didn’t really ever use it. I would recommend them to you.
