If possible, you can try remove the HDD in AIO PC and install it in another desktop PC.  Do a clean install of Win 10 there, then move the hdd back to AIO PC.
Hello, I appreciate that this is a big ask but I'm hoping that someone would volunteer to help me with this issue please. This is the first time I've asked for help on a forum and have normally always managed to obtain exactly what information I needed because someone had already asked for it. So here goes.I've got a lovely Dell XPS 2720 all in one desktop that I'd been running Windows 10 on very successfully until it developed a screen issue overnight. The screen has a block of coloured vertical lines covering the entire width and almost the entire height of the screen. I thought a Windows update had caused this and, after my considerable efforts to resolve the issue, I decided to do a clean install using an external monitor via HDMI as I have no VGA on the XPS. Here is where I encountered the issue of the installation not recognising the external monitor.Is there a PC expert reading this who is able to give me a step by step guide please, of how to inject the latest Intel Graphics driver for my system into the WIM file on my Windows 10 installation media? I am someone with a reasonable ability to follow instructions but limited knowledge of exactly what to do and how to do this and I would be over the moon if I could end up with a working machine using my spare monitor. Thank you. Fingers crossed.
