The TouchSmart is the all-in-one kind of computer. Apparently HP made customized video drivers for this computer which has an NVidia video display. The computer came with Windows 7 and worked great. When Windows 8 came out, I purchased an update license when they had the $15.99 special. I installed Windows 8 but when it was all done, nothing but a black screen. A check of the HP web site revealed that HP would not be supporting this computer into the Windows 8 era due to its age. I downloaded the latest NVidia driver but it would not work (it wasn't customized). Somebody out there created a customized version of Windows 8 with drivers that did work. I found it on-line and downloaded it. It did install OK and the video drivers contained in the .iso worked properly. Now I would like to upgrade to 8.1 and 8.1 2014 Springtime. So I'm wondering if anybody here has had any experience with this computer and found a way to install Windows 8.1 on it? Any suggestions would be appreciated very much.
