Two days ago My ASUS N750JK notebook crashed after I inserted the headphone jack into the headphone hole. The same headphones work fine on a different notebook. Actually, I had briefly put the jack in the mic port, my bad, then I immediately moved it to the correct headphone hole, then Windows 10 crashed with some generic screen. I guess it was a short. After that, the notebook could boot but it would shutdown after a minute or so, even if I booted to just RAM check or to rescue media. Therefore I disconnected all cables, gently removed the internal battery, pressed the power-on button for ten seconds, mounted the battery back to its place. Then the notebook could boot without shutting down. Now it is working fine, mostly.
I say "mostly" because I've just had another "incident" today during a main Windows 10 upgrade. While the notebook was rebooting it shut down. Tried again and again. Eventually I had to pull the battery and put it back. By so doing, upgrade was completed with success. This time, I was not using a headphone. The battery is new, I replaced the old one last week.
To tell it all, this notebook has always given me some concern. In the past it had occasional shutdowns --just sudden shutdown as if the battery was removed, but it was fully charged and firmly placed-- let's say a sudden shutdown every couple of months or something like that. In the past I could boot again after the shutdowns though. No headphones, no other apparent reason. Just some Kernel-Power critical events in Windows logs.
When it was new-ish I even sent it to ASUS for repair because it eventually broke down entirely: it was like dead, they replaced the mainboard and some other parts. But the "sudden shutdown" issue came back later on. I suspect that it might have something to do with CPU temperature or with some ASUS utilities, but I don't really know. The notebook seem to get pretty hot, Core Temp reads 100 degrees (Celsius) just now, I could cook spaghetti on it, and I am just using FireFox to write this post, then there are Windows Security and Malwarebytes real time, overall CPU usage around 7/10%, the fans seem to work . I am not clear if 100° C is too high or it is normal for an i7 4700HQ (Haswell).
Also, the speakers crackle a bit. It never was crystal clear, possibly it got worse.
I've tried and uninstalled the audio driver, then Windows reinstalled a driver at boot, but still no joy. I also disabled whatever I could: sound effects, spdif port, line out. Latency is a bit high even if I switch off WiFi, airplane mode. I am pretty confident there is no malware involved.
Maybe some of the issues are not related but I tried to draw the full picture.
