Help with hard shutdown

Teabag_Terry2 · 25 Nov 2014 at 18:31

Yesterday I powered up my pc as normal. It booted into windows, and was fine for about 30minutes then just shutdown as if the power lead had been pulled out, then rebooted.

No dump file.

It is DEFINITELY not GPU, PSU. Could bad ram have caused this? I am using corsairs basic cheap one.

I am running a 2600k at 4.9Ghz, 1.44v, and a 980 on a superflower 850 leadex gold.

Any ideas? All cables are seated correctly and temperatures are all low as hell.

how much ram are you running? and what mb

4 sticks of 2Gb ram, corsair brand.

Asus Maximus IV Gene-Z, all bios fully up to date.

has it always done this or just recently? only thing that pops out is the 4x 2gb sticks usually from older boards,could be some sort of compatibility issue

could try with 1.06v vccio/sa whatever ones at stock 1.05v

Would faulty ram cause a hard shutdown? I would have thought it would have been a BSOD with a dump file?

it can sometimes,just instant off/restart

tried stressing it with prime95/blend test? usually that will find unstable ram pretty quickly

Might have to get me some new ram then. Problem is that its a mATX board and I am using a huge Noctua CPU cooler. Can anyone recommend some ram that will go with my board but doesn't have silly massive heat spreaders on it? The sticks need to fit under the cooler!

Edit: nothing I do can force it to happen. Heaven 4, superpi, prime95 and memtest.

im using some Samsung green memory with my d14 cooler

some corsair lp ram should fit aswell

use memtest to test the ram and see if there is any issues

Maybe, it could caused hard shutdown when PSU activated overvoltage protection. The same thing happened to my mate PSU.

Is your memory overclocked? Try run CPU, GPU and memory at stock speed and see what happen after 30 mins.

Just did an hour of 64 player BF4, everything maxed at 1080p. 120+fps 99% of the time, but can't manage to get the hard reset again. Will probably never figure it out, although if there's a tasty deal on a X99 5960X combo on black Friday I might treat myself to some crazy new gear. Balls, just realised Gibbo said no deals on CPUs. FML.
