URGENT >> Computer Randomly Turns Off?..

I have a custom built PC that I built a few years ago.

>>>>>
Case : HAF 922 Mid Tower Case by Coolermaster
Motherboard : ASRock Z68 Extreme3 Gen3
CPU : Intel i5-3550 LGA31155 Quad x4 core 3.3 turbo boost to 3.8 processor Sandy Bridge
RAM/Memory : 32GB G.Skill Ripjaws 1600 Speed Gaming Ram
GPU : EVGA SuperClocked GeForce GTX 560 2GB SLI Video Card
Main Drive : 120GB SSD III
HDD : 1TB Seagate 7200RPM 6.0GB HDD
Power Supply : Corsair AX850 Modular Power Suppler Professional Series Gold Certified
CPU Cooler : H70 with Cougar Performance Fans
>>>>>

About a year after building it, it would start to randomly turn off. (Was a sudden switch off, then it would turn back on after a few seconds).

This would happen every few days, so I replaced the power supply.
After replacing the power supply, it stops for about 8 months, then the problem starts again.
I do not overclock. My CPU, GPU and RAM temperatures are fine.

This is my 3rd time replacing the CPU, and the problem has started again..

I have just use the Intel Processor Diagnostics Tool (which puts a heavy load on the CPU), and it passed the test 57 C below the maximum.

Some other things I have tried are cleaning out my CPU fans, and I have re-installed windows.. Twice..

Any suggestions?

There could also be other things then a bad power supply, like a bad motherboard or a RAM stick that's not functioning properly. You should try to do a RAM stress test, and if that completes succesfully you can almost say that is must be the mobo.

Hope you'll fix this because PC's functioning unproperly is very stressfull(trust me i know)

Yes, it is very stressful :/ 
But I still feel that it could be the PSU, because every time that I replace the power supply, it starts working for about 6/7 months.

Could this still be a problem other than the PSU?
Maybe I should try a higher wattage?

(NOTE : I just noticed that I posted the wrong GPU! I am currently using a 7870 2GB with triple monitors. The computers PSU is plugged directly into the wall outlet, not a outlet splitter.)

Thanks!

nice your running triple monitors :p 

but i'm 100% sure you don't need more wattage that power supply is more than great you could even run your pc with a 600 watt silver certified power supply with one hd 7870.

Another thing could still be that a component in your system might be killing your psu's way faster then normal.
But if this is the case it mostly is the motherboard yes.
If your psu's keep dieing after 6 months i expect it to be something else

You should try some stress testing software for your components(it can make the situation a bit more clear)

Hope it becomes clear what the actual problem is :)

I used the intel diagnostics tool to test it, and it passed.
Which tool would you recommend using next? I'm just worried that replacing another part wouldnt fix the problem D:

Intel extreme tuning utility let's you stress test your ram. If that passes everytime just fine, it's won't be your ram.

It could be as easy as a small option in the bios and it could be a little chip on your motherboard artifacting which you will never find out unless you change motherboards. To me ASRock is a good brand, actually it was a sister company of Asus in the past. But other than this i really don't know what it would be, except the gpu that also could be artifacting on a strange way. Too me i would stress test the ram and if that passes it would be the motherboard or the graphics card. To sort out it's the graphics card you could run your pc a few days on the intel hd graphics, and if it still shut downs running on the hd graphics it must be your motherboard.

long story short: You can sort out it's not the gpu or the ram, and if the gpu and ram works fine it just must be the mobo.

thanks for making my brain work hard :p

It's been about 1 and 1/2 months now.
Here's an update, and maybe someone can find out why exactly it was occuring?

Well, I have 32GB of RAM. 8GB x 4.

Lets think of these 4 cards as card A B C D.

I had A,B,C,D all installed, with this, it was shutting down.
I removed all cards but left A,B and it worked fine.
I removed all cards but left C,D and it worked fine.
Weird, huh..

So, I went with card A,B for two weeks.
After two weeks, I put card C,D back in, and it's working fine..?

Weird, isnt it?


So it seems that my solution was taking out any two cards and running with 16GB (rather than 32GB) for two weeks.

That is strange. Is all of your sticks the same or are some faster than the others? I would recommend running Memory Test 86 on your computer to see if any of your ram is having problems.

http://www.memtest.org/

Also what is your RAM voltage set to and are you using XMP profiles?

Thanks

They're all the same sticks. I have tried running MemTest86 for around 12 hours, no problems.
It's been running fine with all 4 sticks in for a few days, so I dont think anything is wrong..

Plus, keep in mind that every time I replace my power supply, the problem goes away for 5-6 months.

You should add 0.05v to all the 4 ram sticks and try again :)  it could be the 4 dimm slots are a little underpowered and give some minor problems.
