Hi,

I have a Dell Vostro 3550 that I use for light tasks when I am at home. Recently, I decided to upgrade it and replaced the hard drive with an SSD and upgraded the memory to 8GB. I also upgraded it from Windows 7 to Windows 10. However, on Windows 10 the display does not function correctly (as it did in Win 7). It is not an issue with the display as it boots into the BIOS fine but in Windows, it just goes blank. I have also tried installing Ubuntu to see if the built-in display works there and it is fine. I also tried connecting the laptop to an external display when I booted into Win 10 and it is fine there as well. The only thing that does not work is the built-in display when I boot into Windows 10.

Thanks for your time.
