My specs:
intel i5 2500k cooled with cooler master hyper 212 (overclocked to 4.4ghz with cpu voltage offset +0.020v)
asrock p67 extreme4 gen3
ocz zx 850w
corsair 600t
g.skill ripjaw X 1600 dd3 (x2)
windows 7 64 bit
hd 6950 sapphire toxic 2gb (not overclocked
crucial m4 120gb
samsung spinpoint hdd 1 T

My problem started when i reinstall everything. My computer randomly shuts down and fans starts to turn on full blast. I leave it for 5 minutes to see what happens and it seems that it wont stop doing that so i have to keep turning it off by either pushing reset button and then shutdown button on the case or unplugging the psu and turning back on.

It reboots with typical windows error asking if i want to start it normally or with safe mode. This problem occurs very random. Sometimes it takes 3-4 days for it do it again sometimes less than an hour. I check the cpu temp on bios and it says the temp is 46C so its not the cpu overheating.

So i reinstall windows 7 as I rma my ssd. Went and install all updates for both bios and windows. I re did the optimization of the ssd too. I used to overclock the graphic card but this time its not. I have msi afterburner running a manual fan set up that i did. it never pass 70C. I installed hw monitor for cpu temp and its max is 63C and i researched that this type of cpu can go higher than 70C.

I googled the problem and it seems this is not a very familiar problem at least in the internet. Anyone have any idea what cause this or could advice on finding out whats the problem? Thanks! :)

you may have to aggressive of an overclock on the CPU. Have you done any stress tests on the machine to ensure its a stable overclock?

also you may have bad ram. use a program called memtest86+ to check your ram for errors

this happens before i reapply the overclock. Also i already had this overclock set up for about 2 years now with the same system i have now except the ssd is replace but with the same model only refurbished. It just happens 30 mins ago and I am running my computer again as I write this post and playing FFXIV.

In order to identify the issue you must first return all the components that are overclocked to stock speeds.

That will help rule out any hardware issues, then we may move forward to assessing any software issues (if applicable).

Nothing was overclocked when it happend although this first happened when i was optimizing the ssd. it happened as i was on step where i have disable prefetch and superfetch. I followed this website on how to do it http://www.thessdreview.com/ssd-guides/optimization-gui...

Its the same website i used when i optimized my ssd but i think its been edited.

Why would you say that without looking at reviews for that model? You might want to take a look at the reviews, like this one by Gabriel Torres of HardwareSecrets (linked to conclusion page) http://www.hardwaresecrets.com/article/OCZ-ZX-Series-85... - they don't get rated any higher

You have a fine PSU there, changing it probably will not help your issues

I agree with WarWolverineWarrior, it sounds like your PSU is going bad. When my last PSU went bad, was an OCZ too, not that model though, my issues sound almost identical to what you are going thru. I would suggest if you have a spare power supply, run on a different PSU for a while see if the problem goes away. It is worth a try to rule it out anyway :-)

His PSU is of fine quality: http://www.eggxpert.com/forums/thread/323050.aspx

We need to rule out the possibility of PSU failure.

Byakki, do you have access to a spare PSU/PSU tester so that you may rule out this possibility?

Agreed, nothing wrong with the quality, but even the best quality power supplies go bad sometimes :-)

OCZ has a bad reputation with their products failing. General rule in building PCs = Avoid OCZ

Their build quality is only questionable in those entry level units, the enthusiast and professional models are decently reliable.

I don't so i have to buy 1. The psu still has 2 year warranty out of 5 year so if thats the case i can just request an RMA but I haven't been given any reason that it's the PSU problem.

Anyway I ran a memtest86 for 40 minutes and pass the first cycle with no errors. I stopped at 50% on the 2nd cycle as it seems to take a long time, probably will run it when i go to work tmr morning.

I ran a prim95 for 1 hour and no errors and seeing the temp on h/w monitor, out of 4 cores running, max temp is 79C.

About getting another psu to try out, my bro has 550w ocz fatality psu idk if thats enough to power mine. It's been running for more than 3 years now and no problem so I gotta disagree with others says about ocz.

Any make of PSU can fail, it's not just an OCZ or cheap PSU thing. Just because you buy a good quality PSU doesn't mean it isn't gonna fail, it means you have a lesser chance of it failing. The symptoms you are having, PC randomly shutting off, in my experience, can be symptomatic of a power supply failure. 550W is plenty to run your system off of, just lay off the overclocks, so I would recommend borrowing your bother's PSU for a while or maybe switch and he uses yours to rule the possibility out. There is no way to know for sure what is wrong with out troubleshooting, or switching parts out till you find the culprit.
