Random PC Crashes/Reboots

Recommended Posts

Date Seen:
Started happening about a month ago (5/1/2019)


Live server/game client


System Specifications:
Operating System: Windows 10 Home OEM 64-bit

Motherboard: Asus - STRIX Z270G Micro ATX LGA1151 

CPU: Intel - Core i7-770K 4.2 GHz Quad-Core Processor

CPU Cooler: EVGA - CLC 240 74.82 CFM Liquid CPU Cooler

SSD: Samsung - 960 PRO 512 GB M.2-2280 SSD

Graphics Card: EVGA - GeForce GTX 1080 8 GB FTW 
RAM: G.Skill - Trident Z RGB 16 GB (2 x 8 GB) DDR4-3600

Power Supply: EVGA - SuperNOVA G3 750 W 80+ Gold Fully Modular

Full explanation of issue/Troubleshooting attempted:

My computer is experiencing random crashes. There is no real pattern, but there are a few constants.

1) PUBG is running/in-use.
2) Discord application is open/in-use

I've troubleshooted and diagnosed a few leads, but to no avail.

1) After some internet searching the most obvious problem was that the power supply is failing - I contacted EVGA and ran through some troubleshooting: the voltages are fine before/during/after a random crash. Being as this situation has gotten worse, I've gone ahead and purchased the same PSU (it will be here June 15th, 2019) to continue testing this theory.
2) It is NOT temperature related - all temps are in the normal ranges during load. (CPU/GPU)
3) I have removed all overclocks and reset the motherboard/cpu to default settings. These seemed to help only slightly, but the crashes would happen sporadically. Some days it would crash only once, others it would crash 10+ times. This is still the case.
4) The computer auto-reboots after the crash. 9.9/10 times there is NO windows error after the reboot. However, on the rare occasion there is, I have tried to repair startup and it has failed.
5) More discussions with EVGA lead me to believe that there is something shorting on the motherboard. Normal usage of the computer will NEVER cause the reboots. 

6) Troubleshooting steps taken include:

           a) Ran CPU diagnostics using Intel's Processor Diagnostic Tool : passed with no issues

           b) Ran CPU/GPU stress tests using ASUS ROG Real Bench (Version 2.44) [30 minute and 15 minute tests at full load]  : passed all tests with no issues

           c) Ran Memory Tests using Windows Memory Diagnostic : passed all tests with no issues

           d) Completed ALL steps in the READ ME for this thread

7) PUBG seems to be the catalyst and I'm not convinced this isn't a software issue. It has crashed in the pre-game lobby, during the loading sequence, early game, mid game, late game, post game (most common). 


          a) Most crashes result in PUBG losing/deleting all of my player settings. Lately, I don't even make it through re-entering my settings before it crashes again.
          b) Some crashes result in me having to unplug/plug back in my keyboard (Anne Pro 2)
        c) Nobody in the game/discord realize I've crashed because it doesn't appear that I'm gone, until I'm already back. (unless we're in game and my character is just perusing through pochinki fields
          d) There is NO real pattern. It could happen anytime when PUBG is running. Uninstalling/deleting local files/reinstalling helped for an hour or so, then the crashes were back.
Thanks for reading and for any advice!

Did you try to prefer maximum performance instead of optimal power

I will give that a go this morning and report back. Thank you!

Unfortunately still experiencing the crashes. Was in training mode for about 20 minutes with no issue but right when I joined a party with a friend and started queuing - it crashed/rebooted.

Try turning off "Hardware Acceleration" in your browser and discord app. I run discord in my browser (chrome) and I have HA turned off in chrome.


You might also want to take a look at the "Gaming" section under windows settings. Make sure all that trash is turned off. Sometimes windows updates will turn it and other shit back on.

 This might be general trick here not specific to gaming controls but still it might help.

  • Empty Recycle Bin once in a while
  • Defrag your disk regularly may in a month or so
  • Disable unwated services in background
  • Adjust graphics on other unwanted places

Let me share a good info graphics here.
