PC does a hard reboot while gaming

[Trieclipse]

Happy Saturday everyone,

 

I have a PC with a 650W eVGA SuperNOVA GS Power Supply running an ASUS Z170-E Motherboard with a Core i5-6600K, ASUS GTX 1070 Strix, 16GB of DDR4, an SSD, and not much else besides USB peripherals. The OS is Windows 10. I have recently updated to the latest BIOS, Chipset, and Video drivers.

 

The PC will randomly restart in the middle of demanding gaming sessions. I can hardly get through a round of Battlefield 1 or PUBG without a restart. I have been able to replicate the issue while running video card stress tests (3DMark and Unigine Heaven). I've tried working through the normal troubleshooting process - it probably isn't due to an underpowered power supply, 650W should be plenty to handle this configuration. The 12V rail is delivering consistent power slightly above the 12V target. I've also been monitoring temps of course, and there is nothing much out of the ordinary (GPU tops out at 72*C max in a hot room, CPU doesn't break 65 on any core). I've tested the memory, no errors. Nothing is overclocked (it was, but that was the first thing I un-did when I starting running into this issue).

 

I admit my cable management wasn't the greatest behind the PSU, so it could be overheating, but there is nothing obstructing the air intake at the bottom of the PSU, or the exhaust at the back. When the PC reboots, it is a complete shutdown, all lights and devices turn completely off for 2-3 seconds before coming back to life. Recently, the video card fails at boot (it turns on but no video signal goes to the monitors). In these cases I have to turn off the PC and wait 30-60 seconds before trying again if I want a signal to my monitors. Sometimes it will reboot multiple times in succession on its own before even loading Windows. 

 

My main suspicions are issues with the PSU or the video card. Possibly a loose connection somewhere, but I just ran a stress test of 3DMark FireStrike Extreme for 20 minutes before reboot, so I would think a loose connection would have made itself known earlier. Memory temps are not high but I have heard some memory sticks have overvolting protection, I'm not sure if that might be the issue.

 

I should note that Event Viewer is not helpful. It is meant for BSODs and it records nothing but my own, intentional reboots when my monitors don't load.

 

Thank you for your help!

Any overclokcs. And looks like too much power but that dont make sense

Sorry wrong thread

How old  is the system?

[Trieclipse]

Nothing is overclocked, all CPU and Video Card and Bclk frequencies are at stock. 

 

The PC is about a year old, but I have been dealing with this issue intermittently over that time. I had this issue in the beginning, it went away for a few months, and is now back with a vengeance.

 

I have recently air-dusted the insides, but dust would mainly contribute to heat and my temperatures have not been in dangerous territory.

Well its a case of going thorough things one by one, remove the power supply and clean all the connections, reconnect them one by one cleaning out whatever there connected to as you go, sort the wireing out on the way.

If after that your still having the issue could you try another power supply ?

Have you took the GPU out to make sure there is no dirt or dust in its slot ? or its power connections ?

Have you updated GPU drivers ?

What cpu cooler are you using ?

I ruled out the video card by switching my 1070 with my brother's 970. The PC still restarted while running the 3DMark Fire Strike Ultra stress test. The TDP difference between the two cards is only 5W so they're roughly equivalent.

 

I then went ahead and re-did the wiring, reconnected all the plugs, blew some compressed air into the PSU and throughout the case and different components. Some dust blew out of the PSU, not a lot but more than I expected considering the dust filter is in good shape and the rest of the system doesn't have too much buildup. So far I've completed two Fire Strike Ultra stress tests and two long rounds of PUBG without any issues.

 

I would hate to jinx myself because it's still early, but I think the issue may have been fixed.

Has this happened again since your last post? I've been having this problem for some time now and would like to know if just cleaning the PSU would stop it from happeing.
