I had been using Geforce Experience for some time, even before I got my GTX 980 last year. Recently I had upgraded my PC adding a second GTX 980 in SLI, and upgrading to 32GB of system RAM. I had been using the same install of windows 8.1 for about 9 months, and after the upgrade my PC had a very awkward slow boot up, that I now know is due to Geforce Experience software.
What happens is after my PC boots, I tap a key I then enter my password as normal and it takes me directly to my desktop, except I have no desktop icons. My desktop is usable, i can draw a box on my desktop, i can right click and get the context menu, I can use the taskbar, but none of my other startup apps have loaded up yet, almost no icons in my system tray. it’s like half-ready to go, something is holding it back from loading up everything I want.
It will be like this for a good minute before my icons appear my start up apps load and run, and then I can do something on my PC. It didn’t do this BEFORE my upgrade. So I though maybe my boot drive was getting to full. So I decided to clean install windows 8.1. That did resolve the problem with my desktop icons not showing up after login. BUT once I installed GeForce Experience software, this behavior came back!
GeForce Experience didn’t do this when I only had 16GB of system RAM, and a single GTX 980. For some reason GeForce Experience doesn’t like my upgrades. I don’t know if it’s due to going SLI or having more ram, maybe both, but uninstalling it restores my PCs behavior after logging in. So screw GeForce Experience when it screws with my experience with my own PC.
