System crashes but no BSOD

Hi all,
 
Hope it’s ok using my first post to troubleshoot, but I’ve been having a lot of crashes with a custom build PC. I’ve had it for a couple of years now but these crashes have been persistent from the start but rare enough to not be a massive issue till now.
 
Basically it crashes when the system’s under stress (usually gaming) but lately I’ve been experiencing crashes even with old games with low system specs. It just restarts without going to the BSOD so I haven’t been able to find a record. The event viewer only states that the source of the crash is kernel-power, but this just means it restarted without shutting down properly and doesn’t tell me the source. 
 
I’ve checked the drivers are up to date and RAM for quality with no errors. Any advice to try to pin down the cause of this would be hugely appreciated, it's been driving me nuts.
 
Specs:
Intel® Core™ i7-4790K CPU @ 4.00GHz
NVIDIA GeForce GTX 970
Corsair Hydro H100i Watercooling Performance Closed-Loop CPU Cooler
16GB (2x8GB) Corsair Vengeance Jet Black Low Profile 1600MHz RAM
250GB Samsung 840 EVO Series 2.5" SATA 6GB/s (SATA-III) Solid State Drive SSD
Corsair CS750M - 750W Semi-Modular 80+ Gold Power Supply
Windows 10 (64 bit)

Not that much to go on... I had 2 similar cases on my pc, crashing without BSOD:

 

- RAM error, you write you tested RAM... test more, mine appeared after 24 hours of testing, RAM was on the verge of breaking but would not always corrupt immediately. I then replaced one memory module and everything was ok again

- GPU overheating, in most graphics cards there's only a small fan. After a few years it collects too much dirt and doesn't work anymore 100% correctly. Effect you get is that after some time working/playing games the computer crashes, the better the graphics you use the quicker it overheats and crashes, and crashes will become quicker and quicker.

over heating most likely,

 

could be your video card or your processor, one of the two is getting too hot

Thanks for the replies. I'm going to run some hardware monitor tests to try and get some temperature readings, but these crashes have been happening even when the system was new so I doubt it's a build up of dust.

 

Hopefully it's just bad RAM. If it's not and it turns out it is overheating, what would you suggest?

did you apply thermal paste properly to the processor heat sink/fan when you built it?

 

take that apart and clean the old paste off and apply new paste,

 

do the same thing with the heat sink/fan on your video card

 

and while you have them apart clean any dust from the heat sinks and fans

^ It was built by a company so I didn't do it myself unfortunately. However, I'm currently running FurMark with some hardware monitor ware and all temperatures seem reasonable - GPU is currently maxing at 79 so I might try de-dusting but it doesn't seem to be overheating yet. 

 

I'm pretty new to this but it's also showing the i7 CPU core #1 at 100% while all others are fluctuating between 1-10% - perhaps that?

download and run speccy

 

that will show the temps of your processor and video card

Power supply as written in OP is Corsair CS750M - 750W Semi-Modular 80+ Gold Power Supply 

 

Apologies for making a new thread, but since the problem wasn't a BSOD but a crash I wasn't sure it applied.

No need to apologize — I should be the one doing so in fact. :wink: I ask members not to create a new thread as the BSOD posting instructions actually ask you to do so. That's because the author presumed that the member reading the topic had not requested for help yet at all and would follow the instructions before starting a new topic. Anyway, please run the Sysnative File Collection App regardless of whether you're experiencing BSODs. :)

 

Thanks.

 

Best regards,

Thanks for the input and sorry for the delay. I've attached the SysNative zip and the Speccy details. 

 

http://speccy.piriform.com/results/yQUDEnEoM5P8MTlADA4PsAP

 

One thing I noticed - I recently ran FurMark and found that core #1 of the the i7 core CPU is at 100% while the others are all fluctuating between 1-10%. Is this normal? 

 

Thanks for your help.
