Random Restarts

samsamm777 · 26 Jul 2017 at 09:36

I've been having this issue for a while now, and its starting to be a right pain. My pc will just randomly restart/cut out sometimes when im gaming. I've done all the normal diagnostics I can think of, checking events logs for any errors, logging temperatures of gpu, cpu etc and nothing seems to be out of the ordinary. Im starting to think i might have a duff PSU. As it appears like the mobo just loses all power, theres no attempt to 'shutdown' which i think would happen.

Anywho.. heres what my kit is..

Intel Core i7-5820K 3.3GHz 6-Core Processor
Asus RAMPAGE V EXTREME/U3 EATX LGA2011-3 Motherboard
Corsair Vengeance LPX 16GB (4 x 4GB) DDR4-3300 Memory
EVGA GeForce GTX 980 Ti 6GB Superclocked+ ACX 2.0+ Video Card
Corsair CP-9020056-UK RM Series RM850 80 Plus Gold 850W ATX/EPS Fully Modular Power Supply Unit

If anyone can give me some pointers, i would be hugely grateful.

Have you run mem test on your ram ?

Could well be the PSU - but could equally be something else emulating a similar problem.

What were your CPU/GPU temps under load?

What cooler have you got strapped to the CPU?

A few things you could try to help resolve or get closer to identifying the problem. The ideal would be a trying a different PSU or GPU.

If any of your system is clocked remove them.
Double check all your connections and hardware is seated properly - ideally remove and reseat all of them - including SATA leads etc..
Check the kettle lead is securely fitted into the back of the PSU
If using an extension lead try plugging PC directly into the wall socket - or a different extension lead.
Update BIOS
Clear the CMOS and load optimised defaults and set the BIOS settings back to what your HW needs (again leaving off any clocks).
Try with just 2 sticks installed (after a few runs of memtest)
Check motherboard is securely fitted - no movement.
Try a stress test on GPU and CPU independent to each other - and see if you get a similar error with either.
If they pass try running a blended stress test such as Unigine Valley Benchmark - see if that emulates the same problem when gaimg.
Make sure all drivers are upto date

Best of luck.

I have done a memtest, all OK. ive also change the ram for good measure.

these are some good points, ill go through these and let you know my findings. I have a corsair corsair h100 cpu cooler, which i have recently cleaned the fans and radiator out to ensure theres no heat build up. my gpu is stock cooled.
