System Randomly Reboots

Hello community,

For the past couple of months my system has randomly rebooted while playing World of Warships. This only occurs while playing this particular game and at no other time. I play many other and more demanding games without issue.

Event viewer shows no critical errors other than Kernal power - system shut down unexpectedly. I get no blue screen it simply hard reboots.

I have replaced my GPU since this problem began. I originally had a HD 7950 which died and I replaced it with a GTX 1060, so I am ruling out the GPU.

I have cleaned/updated GPU drivers, scanned for virus/malware, stress tested CPU and all have come back clean. Temps are good, CPU max 58C and GPU max 62C and nothing is OCed.

Since this has never occurred while doing anything other than playing WoWS which is only a small fraction of my pc use it has me stumped. Any suggestions would be appreciated!

Specs:
i7 4770K @3.5 turbo boost off
Asus Hero Z87
G.Skill Ripjaws 1600 12Gigs
Corsair HX750
EVGA GTX 1060 SC 6G
Intel 535 SSD
Sprintpoint F3 1Tb HD
Windows 10 64bit

You can't, at least not without fairly expensive equipment. Just read reviews to see how the PSU handles 7A load changes. If your unit is indeed the original HX750, it won't be pretty. If it's the HX750 v2, it stands a better chance of not being the issue
Sounds like power issues, the HX750 was never meant to handle the power demands of a maxwell/pascal GPU. Try using the "prefer maximum performance" option in nvidia control panel and also underclocking the GPU by 25% or so. If either minimize or eliminate the issue, you need to replace the PSU with a better unit

Thanks Jasjar I will make a post on their forums and see if anyone else is still having an issue. That thread didnt look like many had this issue and that was back in 2015. So I will leave it open as a possibility but will remain open to other suggestions at this time.

@ Basroil

The HX750 at the time of purchase was one of their better units. It was a tier 2 here at tom's hardware and suggested for GPUs much more demanding than my Gtx 1060. However I suppose it could be on its way out? Im just not certain at this point since I can play much more demanding games without issue but I will keep it under consideration.
 


That was 6 years ago! The WAY cards use power has changed a lot, and they are actually MORE demanding even though they have lower average consumption! You need to check that PSU's transient load response, if it fails a simple 7A load (many old units fail), then it can definitely cause issues in low-medium graphics power games

How can I test the 7A on my unit? My PSU is still under warranty, is this something that would be covered do you think? Or is it simply demands have changed and the unit would be working as it was designed and I would be out of luck with a warranty replacment/repair?
