"Whether it wants to be called Shadowplay, Share or [as of the time of this post] In-Game Overlay; it doesn't really matter to most people I think - we just look for something to record our gameplay once in a while, maybe take some Screenshots, 'and just work'. Thankfully, NVIDIA's In-Game Overlay [or whatever it may be called by the time I get finish this post, heh] does just that. Most of the time.

Although I rotate between a handful of different recording programs off and on (such as Bandicam, Action, Playclaw and others - just for fun and also slowly working on another "Game Recording Comparison" for the future), In-Game Overlay [built into the NVIDIA Drivers, aka for free] records when I want, it records a Buffered Loop (a timed, re-recording of 'the last xyz seconds', to save when needed) - and it even takes Screenshots - and more. However, sometimes this big fella has just 'stopped working' lately. No saving Screenshots, no Recording, no Error Message, Nothing; and I wasn't sure why... After only a tiny bit of Troubleshooting, I quickly figured out one easy way to at least 'possibly get it going again' and I just wanted to share that here for you all.

To be honest , I am still not sure why NVIDIA's In-Game Overlay stopped working, even after looking for Logs/etc - but I did figure out one way to simply get it working again - and here's what I did:

» Once I noticed the Overlay wasn't taking Screenshots, I looked to see if the Overlay itself or more of the (many) NVIDIA utilities were still running, in the Task Manager. They were. [The "In Game Overlay" Executable is still called "NVIDIA Share.exe", btw]
» Thinking that something might have gone wrong with the Overlay utility, I opened up NVIDIA's GeForce Experience.
» In GFX [my accro.], I clicked on the 'gear' in the upper-right corner, "Settings".
» In the Settings area, I clicked on the switch/toggle for In-Game Overlay.
» Although it took longer than normal, it eventually turned Off. Clicking it again, it turned back On.

That's it! After those steps, the In-Game Overlay was working once again. Taking a Screenshot, for example, the notification from the Overlay came up, and the Screen was saved. It also started Recording again, without issue. Here then, is a 'Tutorial Image' of the steps to take, as a reminder or to share with others.

[Edit: If that doesn't work, Rebooting will also get NVIDIA's Share/Overlay working again - but I thought people would be more interested in the step(s) that didn't involve stopping everything and restarting the whole thing, thus I covered just this one scenario/fix]

Although I do not have any details on why it failed, I still thought this short 'tip' would be helpful for people that might run into this ("shadowplay not recording" or "in-game overlay not taking screenshots", etc) - so I wanted to share it here. HTH ~T"
