I am experiencing seemingly random freezing/deadlocking of my Predator Helios 300. Running Windows 10; I have seen this since I got it, but it used to occur once or twice a month now I am seeing the problem at least once a day.
I haven't been able to reliably duplicate it and it seems to occur at random. I have had it completely lock up while monitoring the resources/temp and the CPU/GPU will be in the mid 50-60s. It occurs when gaming or browsing the web, or even just after returning from it sitting idle. I wanted to rule out failing RAM so I ram a memtest86, but I had it freeze twice during that requiring a hard reboot. So I am seeing it freeze even out of the primary OS, Win10. One memtest finally complete 4 passes with no errors, so I am not sure it is RAM.
After a freeze and hard reboot, there is no dump, event logs, or record of the deadlock. I have not received and BSODs or GSODs; system just stops responding and the keyboard colors keep pulsing away mockingly.

Any thoughts, tips, or tricks? I'm really running out of ideas on this. Thanks!
