Random Computer Restart (Black Screen)

[Shamatix]

Hello fellow fans of LinusTechTips,

 

Earlyer this year I bought a computer, with the following specs:

Corsair H100i Hydro Series

Corsair RM850, 850W PSU ATX

Kingston DDR3 HyperX Beast 16GB

Intel Core i7-4770K

ASUS Maximus VI Formula, Socket-1150

ASUS GeForce GTX 780Ti 3GB PhysX CUDA

WD® Desktop Black 1TB

Asus 24" LED VG248QE

Samsung SSD 840 EVO 250GB BK OEM

Corsair Obsidian 450D Midi Tower Sort

 

I get random blackscreen into computer restart, I think it might my a malfunction in the PSU? But I am unsure, this have happened almost from the beginning, but because of my lazyness I havnt sent it back in. The thing it sometimes it can be 2x weeks without restarts while playing games and as now I just had 5 restarts in less than 20min. So It is completely random. I have tested my temepratures and at ultra in Wow I get maximum 50 celcius on my GPU, even if I play on lowest settings my computer can restart, so I doubt its the temeperaturs. I do not get a bluescreen so it's quite hard for me to try find out what fails and I am also quite new to computer and stuff so just been trying to do my best regarding the things people suggest. But I am up for any ideas right now! Please shoot

 

Best regards Henrik V.

Hey Shamatix,

 

Does your build shut down immediately (including all fans, lights and drives) or you get some time between the black screen and the actual shut down/restart? Are there any beeping sounds coming from the motherboard or any error code (before or after the restart)? 

I would test the PSU if it provides stable currents to the internal parts of the computer. If you can, try your build with another PSU and see if it restarts. 

It wouldn't hurt to also test the HDD for any errors. I would recommend downloading and running WD Data Lifeguard Diagnostic tool. Run both the quick and the extended tests in order to check the drive's S.M.A.R.T. status as well as for any bad sectors that might have appeared. Here's a link: http://products.wdc.com/support/kb.ashx?id=eH2UtX.

 

Hope this comes in handy,

Hey Captain_WD Thanks for your respond, it does not shutdown/ restart immediately, sometimes I even have to hold the power button down my self for it to shutdown, and regarding sound, when I am in a game SOMETIMES I can hear a "beep" sound not loud very very low actually and if I tab out of the game it stops the sound, but as soon as I tab in again it begins, but as said this only happends sometimes. Also I can play for like 1-2 weeks without it happening and then yesterday it happends like 5 times within an hour. It is so random. I do not have another PSU but as I needed some sort of christmas wish... I wished for  "Corsair Corsair HX850i, 850W PSU" so I can check if my PSU is the problem.

 

I will run the WD tool when I get home but thanks alot for this answer.

I would advise you to first check your old PSU before purchasing a new one to avoid spending money on unneeded parts. 

Are you sure the beeping is coming from the motherboard? If it does, I would contact the manufacturer's support and ask them the cause of this. Those beeps are error codes that can help you identify the problem.

Could you record (video/audio) what those sounds are? Could be a fan that at certain rpm speed does this. If it comes from the motherboard, it should be loud and clear, just as the initial *beep* sound when you turn on the computer.
