PC powers-down the powers-up again on startup

Post by solo0017 » 18 Feb 2018, 10:40

Hi folks

I've been having an intermittent issue when turning on my PC. Every so often my computer will power-down a few seconds after I press the power button and then power back up again. It will successfully load to Windows and there is never any error message shown. The video I've embedded shows what happens.

Just wondering if anyone has come across this before or could offer some suggestions as to why this is happening.

Thanks very much.

Could be your PSU, did it do this from when you put the PC together or only just start doing it recently :?:

I've personally had a situation on more than one occasion when the PSU after several years degraded to the point it wasn't producing enough power to run the system under load. Simply put I'd boot up and the second I went to game it would shut off, no error, because it's essentially browning out.

Perhaps try a new PSU.

Or even just a good dusting with a can of compressed air - mine was doing something similar recently, and a good clean out, and reseating RAM/GFX card did the trick.

Some thought that it may also be the BIOS doing a refresh. Next boot go into the BIOS, change something irrelevant like current time, save and exit.

This too is a good idea, but invert the can so your spraying inert propellant on your equipment and not compressed air with moisture in it.

It's done it infrequently since I put it together in Nov 2016 but I'm noticing it a bit more at the moment, maybe once a week.

It is a bit overdue for a dusting so when I do that I'll reseat all the components as well. I'll check the thermal paste and replace that, too.

I'll give it a shot and see what happens.

Thanks for all the suggestions. I've contacted Corsair and they have opened a service ticket on the PSU and will replace it if I ship it back to them (Not sure how I will handle the few weeks of Grim Dawn-withdrawals, though).

Just a shot - have a look at event viewer.

In Event Viewer go to Windows Log and then click on System.

See if it gives any information about what might have made it restart.

Good luck.

What wattage is your PSU :?:

What are your systems specs :?:

Could be pointed out to make sure you had a powerful enough PSU in there in the first place. Simply a 400W PSU doesn't put out 400W to your system, it puts out about 360W as most PSU are 80% efficient and lose the other 20% to heat. Not to mention as a general rule of thumb one might say you lose up to 10% efficiency each year as the PSU degrades depending on its brand/quality. If you put a PSU in there that was barely up to the job to begin with your really in the hole as it were from the get go. Don't be afraid to put in a high wattage PSU, your PC will use as much or as little as it needs or so I have been led to believe, a 1200W PSU doesn't necessarily use 1200W. Ask others...

Gigabyte Z170-HD3
Intel i7-6700K
16GB Corsair Vengeance DDR4
Gigabyte 8GB GTX 1070 G1 Gaming

I've just given the case and PSU a bit of a dusting - hardly anything in there - and reseated the RAM and GPU. I'll see how things go and if the boot-restarts continue I'll send the PSU back to Corsair to be replaced.

Thanks for all the comments/suggestions.

A relative of mine had a quirky system that had grounding issues, where if I put the system into 1 case it would not run, but in another case would. How is your motherboard mounted in it's case :?:

Have you tried running the system on an antistatic bag out of the case :?: (turn the system on with a paperclip)
I know that sounds like an extreme thing to do, but if you have a grounding issue it will obviously show if the system runs flawlessly out of its case.
