I've been having an issue where my computer will lock up completely after playing games for a few hours. It's been happening on games like World of Warcraft, Overwatch, BF1 and CS:GO. Oddly enough, this issue has never occurred while playing League of Legends. I've had one 0x00000101 STOP error (CLOCK_WATCHDOG_TIMEOUT) since this has started happening, and it occurred while playing World of Warcraft on windowed mode.

This issue started occurring when I installed new PC parts to replace an older, dying CPU. My specs:

CPU: i7-6700K not OC'd - switched from an i7-3770k
GPU: EVGA GTX780 Ti not OC'd (this graphics card was used on the old setup with no failures)
PSU: Corsair RM850X (replaced an old EVGA 850W PSU to rule out PSU failure, problem persists with both power units)
Mobo: Asus Z170-A (was an ASUS P8Z77-V)
RAM: Corsair Vengeance LPX 16GB DDR4 2133 MHZ (was running 4x4GB Patriot 1600 MHZ DDR3)
Storage Unit: Kingston 120GB SSD + WD Caviar Black 1TB

I've tried a few things already to see if I can pinpoint the issue:

- Ran Prime95 (both Small tests and Blend for 24 hours with no crashes) - Max temps 81C
- Memtest86+ for 12 passes with no errors.
- Replaced PSU (gaming after the replacement PSU installation was fine for about 8 hours before the PC locked up again)
- Clean install of Windows 10 - fixed the issue for three straight days, issue resurfaced again, only installed drivers for my PC, Overwatch, and MSI Afterburner to set an appropriate fan curve to keep my temperatures somewhat low.
- FurMark benchmark test overnight (about 12 hours) with no crashes.
- Uninstalled Realtek Audio Drivers, NVIDIA audio drivers to no avail.
- Reverted drivers from beta to stable to no avail (clean uninstall with DDU before going to stable).
- Re-seated CPU and re-applied thermal paste.
- Checked all power cables to ensure they were seated to the components properly.
- Used different outlets and different surge protectors to rule out power loss.
- Monitored GPU and CPU temps at the time of crashes (GPU would crash anywhere from 64C to 73C, CPU would never exceed 61C while gaming).
- Used CrystalDiskInfo to test both SSD and HDD - SSD health at 99% and HDD health brought up a cautionary notice. Unplugged the HDD and the issue still persisted.
- Updated BIOS/Mobo Drivers, turned off Multicore enhancement.

Is there anything else I can try to fix this issue? Really starting to get frustrated with this machine.

Thanks in advance!

I haven't overclocked anything so far since the problem has happened with everything on stock settings.
