Full System Crash + Restart

[Laming]

Hello friends, I have been watching LTT for quite some time and right now could use some sage advice.

 

My PC has recently been randomly crashing and restarting itself when playing games and what not. I'll be in the middle of a match and boom, PC fully shuts off and restarts immediately. Sometimes it will ask to verify a hard drive's consistency, sometimes it will not. Sometimes it will crash once and I can start back up, and be able to play for a bit before it crashes again. Today it actually crashed, and while it was loading back up, crashed again, started verifying a hard drive and crashed again. Please note that there has never once been a BSoD, always a full crash and restart. Screens turn black power turns off and restarts. My PSU is not in 'Eco' mode. Temperatures are fine, GPU is in upper 30s low 40s upon successful restart, Motherboard says CPU is about the same in Bios. As you can see below, the PSU/RAM/GPU are quite new, 6 months old. About 6-8 months ago my other Seagate 240Gig SSD died, could be that this one is on it's way out?

 

 

OS: Windows 7 64-bit

CPU: i7 4770k (Bought Nov 2013, Newegg)

Heatsink: Corsair H50 with 2 fans(Bought Jan 2014, Newegg)

RAM: 16 Gig G.SKILL Ripjaw DDR3 1600 (Bought Dec 2015, Newegg)

GPU: MSI GTX 980 Ti (Bought Dec 2015, Newegg)
PSU: EVGA SuperNOVA 850W 80+Platinum (Bought Dec 2015, Newegg)
MoBo: MSI Z87-GD65 (Bought Nov 2013, Newegg)

OS SSD: Seagate 600 Series 240Gig(Bought Nov 2013, Newegg)

 

Things I have tried to rectify the situation:

Swapping the power cable

Flipping the PSU from external air sucking to internal

Reapplying thermal paste to the CPU/heatsink

Re-seating all of the RAM

Disconnecting and reconnecting all of the SATA cables and VGA/Perif/CPU cables

Cleaned grills/covers where fans pull and push air from.

Unplugging the PC from its surge protector with 2 monitors, external hard drive and speakers connected, and plugged it into its own surge protector

 

 

I had a similar problem in the past when I first got my 980 Ti. I had a EVGA 650W 80+Gold and it would do the same thing when I would play graphically intense games. Upgraded to the 850W 80+Platinum and it stopped and has not resurfaced. Any help would be greatly appreciated. Please let me know if there's any information I need to supply, I would like to get this fixed soon (:

(There are no dump files, never once a BSoD.)

Have you tried monitoring your temperatures before your computer crashes and reboots?

My suspect is that they rise to uncomfortable levels during gameplay and drop very quickly during reboot.

Are you sure  that you have enabled dump files in windows 7? Check that. If you enabled it then it must be hardware problems. Try not OC first. Then maybe try one ram at a time, then swap PSU, gpu, cpu to troubleshoot the problematic pc part.

I haven't checked CPU, but GPU I have had Precision X up (with Fan Curve set to aggressive), GPU will be around 40-60. Also would like to note that Precision X and GPU drivers are up to date.

 

Yes dump files are enabled. I don't OC, the only thing I have used is the onboard OC Genie, which I have disabled and it still crashes. You think I have extra PSU GPU and CPU laying around? Well I do have a 650W PSU and a 680, but an extra CPU?

Well you have an extra psu and gpu which is good. Try troubleshoot them first then worry about the cpu after.

I ran memtest for 8 hours with 4 passes and 0 errors, ruling that out.

Swapped out my 980 Ti for my old 680, crashed.

Swapped out my 850W 80+ Platinum for my old 650W 80+ Gold, while using the 680, no crashes yet.
