I have had this problem for quite some time. I have a Lenovo y410p with a Nvidia GeForce GT 750M and it is recently updated. All my drivers have been updated also.
When I play CS:GO, this crash happens very often. I will be playing the game, it can even be 1v1 on a private server, and the visuals will stop and it will repeat the last noise played (ex: gunshot). No error message pops up but after a while and a couple alt-tabs, it says that csgo.exe has stopped responding so I stop it. I recorded the temperature of the crash with a program and it was only at 72 degrees Fahrenheit and I also recently cleaned out my fan so I don't think overheating is the problem.
Another game this happens with is Garry's Mod. I will be playing and then it will randomly crash. I will get an error message stating that the graphics card has crashed and I will be able to hear noise and move around in game, but I somehow become invincible (at least on a private server) and the screen becomes frozen.
This crash also occurs when I play Civilization V. After playing for a while, I will start to get some graphics bugs like some textures glitching in and out and eventually it crashes. The crash looks like the screen clipping back and forth from two close positions and the Fog Of War becomes gray and flashes strangely.
Finally, this crash also tends to rarely occur whilst I am playing Hearthstone. It almost never crashes on its own but when I am playing a youtube video or something in the background, that is when it crashes. When it crashes, the videos on youtube freeze and the game does but only for about 5 seconds. After that, the game resumes to normal and I am able to play again.
On all of these games, after the crash, when I boot the game back up again, the crash tends to happen faster than it did last time. For example, if I was playing CS:GO for 15 minutes then I get the crash, if I run it again before restarting, it will crash after only 5 minutes.
If you need any more information on my laptop or details about the crashes, I will be more than happy to answer.
