GTX 560m dying? Artifacts out of nowhere, underclocking didn't solve

Hey, bought a second hand Clevo two months ago. Did mild overclocking as suggested on multiple site (920 core, 1625 memory). Used MSI Afterburners.
The problems started with Heroes of the Storm crashing driver (375.63). Then LoL started acting up, same issue. I thought it's just problems with Hacking Protection (both games warn overclocking might crash the game).
Temps are fine, before OC temps were over 90C, after OC temps stay a constant 76C (VRAM bottlenecks).
Played Witcher 2 Enhanced, some crashes but the game is known to be glitchy, OC didn't seem to be the issue.
About an hour ago, after DirectX11 patches for CIV6, driver started crashing randomly. Artifacts started in all games and desktop. Underclocking did show no change, artifacts appeared the same). Reinstalled driver, artifacts in desktop stopped but games crash driver/BSOD.
It's funny because the artifacting started as driver issues. I run a legit win7 ultimate with all updates. About a month time between driver started crashing, and artifacts appeared. Currently in safe mode. Kombustor retrieved 5 fps and crashed. (down from 20 - *Kombustor always crashed after 40 seconds, kinda peculiar but never paid too much attention).
How can I find out for certain whether it's the silicon dying, or something else (driver/API). Uninstalled DirectX (regedit method) and downloading June10, 11.2 release, will update tomorrow when download finishes.
Any software to test whether it's the driver or silicon? a safe mode enabled stress test to make sure the silicon is ok?

If your stock temps are 90c, I'd suggest replacing the thermal compound and cleaning out the inside. Considering the age of the unit, it could be the compound has dried and needs to be replaced.

I use Arctic MX-4 in my laptop on the CPU and GPU and it lowered my temps by 10c. Plus, if not using a cooling pad, it's highly recommending if you are gaming.

The latest nVidia driver is 376.19.

First thing I did was change the paste. Didn't test temp without OC though.
Didn't know there was a new driver. Thanks.
You know of any way to discern if the silicon is still in order?
