It attempts the upgrade and then indicates that it cannot complete the upgrade and removes any of the changes that it has installed. When ever this occurs, it takes about 5 hours. Apparently DP35DP is no longer supported. What do you recommend as a replacement for continued business use.?
Your motherboard is not supported on Windows 10.
Also, Intel no longer makes desktop motherboards. You can find motherboards available at EVGA, ASUS, MSI, etc.
It would not be worth "replacing the board". To do so, you would have to find a board that supports your processor (also not supported on Windows 10), memory, etc, and fits your case.
It would be easier to simply purchase a new desktop machine that already has Windows 10, and move your data to the new machine. If you have applications installed, find their install media, or be prepared to purchase the latest media from your vendor.
Thank you very much to Al Hill for the information provided.
I just wanted to confirm the information posted previously, on the following link you will be able to confirm that the board does not support Windows® 10:
Any questions, please let me know.
