PC Randomly shutting down

[avatar0527]

Starting about a week ago, my computer started to shutdown randomly without any warning whatsoever. No BSOD, or any error message, it just simply shuts down, and starts back up again in 5-ish seconds. This random shutdown thing has gotten gradually worse over the week, to the extent where the computer now shuts down after 10 minutes of use, or even during boot at times.

 

I don't thinks it's temps related, as I've tried monitoring temps using CPU-Z for the short while I have before it shuts off.. 

 

Anyone else encounter something like this? Any suggestions or information on the situation?

 

Here's my PC specs:

 

CPU: i7 4770K

GPU: Gigabyte GTX 670 Windforce edition

Ram: 8gb Corsair Vengeance LP 1600mhz DDR3

PSU: Corsair GS600

MB: AsroCK Z87 Extreme 4

Storage: Kingston Hyperx 3k 120gb + 1tb Seagate 7200 HDD

 

I haven't done any overclocking at all, for any of the components as of yet.

Sounds like it's a problem with the PSU. 

Make sure all the internal power cables are completly plugged in.

And if possible, try the PSU in a different system.

As @Volbet said, It sounds like a PSU problem. Try testing it without it being connected to any of your components. You can power on a PSU like this by shorting out a green wire with a black wire on the 24 pin cable, by using a paperclip. If the fan turns on, your PSU is at least functional. I don't think it is anything to do with the PSU not being able to power your system, 600w is more than enough.

 

Also, welcome to the forum!

Yeah I had my suspicions, but I didn't want to proceed to buying a new PSU without actual confirmation.

I've double checked all cables (I even unplugged, then plugged back all the cables ), but that didn't fix the problem.

I can't test my PSU in any other system, but I'll definitely try the paperclip method and update you guys on what happened.

Also, thanks WhatTheQuack

Probaly PSU , like other have hinted . maybe ram related or mother board issues. try clearing the bios & reset (atleast) but first of all, check weather its a virus or not.

 

 

post back weather it works or not

I've tried the paperclip method, and the PSU seems to be working..

I've also noticed that the frequency of the shutdown seems to increase throughout the day, as I am usually on the computer for +6 hours. On the first 'on', it stays on for about 2 hours before shutting down, then it's 30 minutes, then 10, and so on.

So now I'm scratching my head over the issue because I'm not sure what to do next.. I'm guessing it has something to do with heat, considering the frequency, but when monitoring the temperatures, everything seems fine..
