Pc Power on Turns Off and Powers Back on Again

samsiun · Oct 8, 2014 16 0 10,510 0

How-do-you-do there,

Today my PC has been turning on for a few seconds before turning itself off. When I press the ability button, all fans (CPU fans, GPU fans, case fans, PSU fans) work properly, but after a few seconds everything shuts down. Sometimes information technology would show upwardly the BIOS screen before turning off, but most of the time it would just turn on and off pretty much instantly.

I did accept this exact problem a few weeks ago. What I did back so was unplugging the PC and cleaning it. Later on, information technology was able to boot, but it showed the "Reboot and select proper Boot Device" screen, which I fixed by using USB recovery to repair. It (somehow) works fine later that, simply today the same problem came back. I'd like to pin down what to cheque commencement before doing anything.

Specs:
CPU: Intel i3-6100 3.7GHz + stock cooler
Motherboard: Gigabyte GA-H110M-DS2
RAM: Patriot Memory 8GB DDR4-2400
GPU: Zotac Nvidia GTX 1050Ti 4GB Mini (unmarried fan)
PSU: FSP HEXA+ 500W
HDD: Seagate Barracuda iii.5" 1TB

Could it exist the PSU is causing all this, or whatever other component that may exist causing this? How do I check them? I've had this PC for three years, more or less. Whatever help would be much appreciated, thanks!

Hi Alvis, thanks for the help. Solution 1 and 2 resulted in the same fault as before, I did those and it still turns itself off. Nevertheless, solution 3 somehow worked, i went past POST and into the BIOS. Information technology couldn't kick the showtime fourth dimension I hit the power button simply I suppose it's because I reset the CMOS (?). After that, I tried connecting the GPU, and afterward it works, the HDD as well. It boots normally at present, which is weird since all I did is basically reseating the HDD SATA cables and GPU.
I'll reply again if anything happens in this week, merely for at present, cheers for the assistance!
By the style practise I need to look into something more if this happens again? Maybe the HDD is dying, or any other?

UPDATE: Information technology happened again. I ran it once and it worked, then since I idea it'southward fine, I unplugged everything and moved it dorsum to its original location. I tried to boot it upward, merely as soon as I printing the power button, it turns off in a carve up 2d. Any suggestions equally what to exercise next?

UPDATE 2: I restarted it a few times and it has worked again at present. I tried restarting it again a few times as well only to make sure. It seems to be happening randomly now, whatever suggestions?

nosotros changed naught and nothing changed. haha

The practiced and bad news is cypher changed, and then at least we didnt crusade more than damage.

I highly doubt its the gpu but anything is possible.

My suspicions are

its down to luck or whatever butterfly that didnt flap its wings
The psu is dying
Something is off with the hdd that causes a failure to kicking (But that wouldnt explain the pc shutting off)

I would suggest trying different combos of components
eg No gpu , hdd in
Gpu in, no hdd

Failing which you could too attempt just testing the psu with no load past bridging the connexion on the 24 pin pcie

Do note that it is safer to disconnect all components while testing information technology as im not sure how safe it is.

If your system does boot at some point you could also test the hdd by downloading
HDDtune or
Crystaldiskinfo or
Hdd browse
and checking the health of the bulldoze.

I would suggest backing up important data during this time to be condom.

Hello

Lets start with some escalating tests

Power Cycle ( Turn off your computer, Unplug/switch off)
Either Wait for most 15 mins or press the power button, It should attempt to turn on/low-cal up which drains the capacitors of all residual ability
Plug in and attempt booting again

Clearing Cmos/bios
This clears the Bios settings of the moterboard which can sometimes corrupt/have incorrect settings)

Opening up the side panel, look for a jumper that says clr cmos (at the lesser mid right)
Change the jumper to the clear position (aka bridging the pin to the articulate position)
Look for about 10 secs
Reset the position
Try booting up

Blank Minimun Rig
This uses the lease amount of components the reckoner needs to run to endeavour to remove some bug

Remove the Gpu
Unplug the hard bulldoze
Leave only 1 stick of ram ( Which i remember you have only 1 )
Endeavor to boot

I hope this helps
Happy Troubleshooting!

Hullo Alvis, thanks for the help. Solution 1 and 2 resulted in the same error as earlier, I did those and it still turns itself off. Yet, solution 3 somehow worked, i went by POST and into the BIOS. It couldn't boot the first fourth dimension I hit the ability push button just I suppose it'south because I reset the CMOS (?). After that, I tried connecting the GPU, and later on it works, the HDD equally well. It boots normally at present, which is weird since all I did is basically reseating the HDD SATA cables and GPU.

I'll reply again if annihilation happens in this week, but for now, thanks for the help!
Past the style do I need to wait into something more if this happens once again? Perchance the HDD is dying, or whatever other?

UPDATE: It happened again. I ran it one time and it worked, so since I thought it's fine, I unplugged everything and moved it back to its original location. I tried to kicking information technology up, simply as soon as I press the ability push, it turns off in a split second. Any suggestions as what to do next?

UPDATE 2: I restarted information technology a few times and it has worked again now. I tried restarting information technology over again a few times too just to make certain. It seems to be happening randomly now, any suggestions?

Hullo Alvis, thanks for the help. Solution 1 and 2 resulted in the same mistake every bit earlier, I did those and information technology still turns itself off. However, solution 3 somehow worked, i went by Post and into the BIOS. It couldn't boot the first time I hit the ability button but I suppose it'south considering I reset the CMOS (?). After that, I tried connecting the GPU, and afterwards information technology works, the HDD besides. It boots normally now, which is weird since all I did is basically reseating the HDD SATA cables and GPU.
I'll reply once more if anything happens in this week, but for at present, thanks for the assist!
Past the mode do I need to wait into something more than if this happens again? Perhaps the HDD is dying, or any other?

UPDATE: It happened once more. I ran it once and information technology worked, and then since I thought it's fine, I unplugged everything and moved it back to its original location. I tried to boot it upwardly, but as shortly as I press the ability push, it turns off in a divide second. Whatever suggestions as what to do next?

UPDATE 2: I restarted information technology a few times and information technology has worked over again at present. I tried restarting information technology again a few times as well just to make sure. Information technology seems to be happening randomly now, any suggestions?

nosotros changed zippo and naught inverse. haha

The expert and bad news is zippo changed, and then at least nosotros didnt cause more damage.

I highly doubt its the gpu simply anything is possible.

If your arrangement does boot at some point you lot could also test the hdd by downloading

I would advise backing upwardly important data during this time to be prophylactic.

samsiun

we changed nothing and nothing changed. haha
The good and bad news is zilch changed, so at to the lowest degree we didnt cause more damage.

I highly doubt its the gpu but annihilation is possible.

Practice note that it is safer to disconnect all components while testing information technology as im not sure how safe it is.

If your organisation does boot at some point yous could too exam the hdd by downloading
HDDtune or
Crystaldiskinfo or
Hdd browse
and checking the health of the drive.

I would advise bankroll up of import data during this fourth dimension to exist safe.

Good bespeak haha, nothing changed.

I was able to get it working for a few days before it happened once again just at present, so I tried running with GPU and without HDD, and so vice versa. Both results in the same splitsecond turn off. Should I start testing the psu, or should I start suspecting other components too?
Edit: is it possible that the front end cables (power button and usb ports) is shorting itself?

AppleGwava · Jul 11, 2016 714 ix v,365 153

Front panel io is rare simply possible, might be time we tested the more unconventional things
Hmm, i would assume that a front panel short would exist akin to a strength shutdown (holding downwards the ability button)

You can check this past unplugging all forepart console and and so shorting across the ability header one time.

we might exist getting onto something with the psu

This is the calculated power depict for your system, which seems fine

Now that I read the post again, a power pause would result in a improprer boot, causing the need for boot device repair.
That could also explicate why non having a gpu helps because the psu has less load (and peradventure less voltage surges/instability)

Perchance you can try using the computer without a gpu for a while?

Unfortunately this time it won't piece of work even after removing gpu and hdd, or putting in just i of them. Tried to unplug RAM too but it still dies.

I'm about to try this, peradventure using paperclip. But something comes to mind: I read somewhere that shorting the dark-green and black cablevision tricks the PSU to "think" that the PC has started then it'll go along. Does keeping the prune on those pins makes it unable to close itself off, since it keeps thinking it has been turned on over again all the fourth dimension? Whatsoever thought on this?

I'thousand most to try this, possibly using paperclip. Only something comes to heed: I read somewhere that shorting the green and blackness cable tricks the PSU to "remember" that the PC has started so it'll go on. Does keeping the prune on those pins makes it unable to shut itself off, since information technology keeps thinking it has been turned on once again all the time? Whatever thought on this?

Im non sure near that, from what i take read its acting as a on/off switch and then it has to be connected all the time during kicking.

It probably will stay on, but whether it volition affect the arrangement with weird voltages is beyond my cognition.

It might be time for a psu upgrade anyway, a good unit will accept a long warranty and can hands outlast the other components, they tin hardly get obselete (Im looking at you now, intel )

Yeah I'yard starting to consider that also, any recommendations? Should I wait for COVID-19 to cease? I feel similar some components' price has gone upwardly since this pandemic started. Should I buy another 500w or should I get a bigger i? My futurity upgrades wouldn't be much different from what it is right now, merely an entry / mid-level gaming PC

AppleGwava · Jul 11, 2016 714 9 5,365 153

Aye I'm starting to consider that also, any recommendations? Should I wait for COVID-xix to end? I experience like some components' price has gone up since this pandemic started. Should I purchase another 500w or should I get a bigger one? My future upgrades wouldn't be much different from what information technology is right now, merely an entry / mid-level gaming PC

Ability requirement for components seem to be flatlining or going down, I would recommend getting a practiced and reliable model.Should terminal you years. Psu prices havent changed much i feel, compared to other components

Okay cool, whatever recommended brand from your personal feel? I was looking into Corsair simply I'thou getting mixed reviews.

AppleGwava

Okay absurd, whatsoever recommended brand from your personal experience? I was looking into Corsair only I'chiliad getting mixed reviews.

I think psu forum has a few recommended lists. Havent bought anything for a long time
