PC Shutting down randomly!

shrublr · Sep 17, 2017

So I've discovered that I can run my pc for hours on end just using google chrome but as soon as I launch PUBG (Steam Game) my PCs power completely cuts and it continues to restart but fails.

My thoughts are that it is an issue with the GPU due to the fact that PUBG is a GPU stressful game.
The one thing that I can't figure out though is that before it took like 5-10 minutes for my pc to shut down and now it is instant.

I have already reseated the ram, GPU and all of the connectors.

Question from shrublr : "PC Shutting Down on it's Own!"

shrublr :

Just recently (Past few days) my computer has decided that it just likes to shut down all by itself and to get it to start up I just have to restart it a bunch of times and see if the display shows as it usually doesn't.

What I did discover last night is that it will run for hours on end using applications like chrome, but as soon as I launch PUBG (A game on steam) my pc power cuts and it shuts down instantly then attempts to restart and will keep trying until I turn it off. Before it would take like 5-10 minutes for this to happen while playing PUBG but now it just happens immediately

I can't test with any other game because PUBG is the only game that I have installed and even if I did get my pc to start up it would take ages to install another one because my download speed has been really really slow ever since the first random shutdown so now instead of like 7mbs it is only 200kbs (unfortunate).

Here are my specs:
CPU: i7 6700k
GPU: GeForce 980 (Don't know the exact card)
PSU: I don't know because the stock PSU failed and I had it replaced but I am not aware of what they replaced it with.
Motherboard: Gigabyte Z170-HD3
RAM: 32 GB
Storage: 2 TB hard drive and 140 SSD

Sounds like a PSU problem. Look at the nameplate on the side of the PSU and tell us the Make/Model.

Sorry, too late already sent the computer in. I do want to ask, how is this related to the PSU? Is it just that PUBG is a GPU stressful game, so when it is launched it requires more power from the PSU, but the power just can't be supplied because of the faulty supply?

The GTX 980 is a 165W (TDP) card. It can consume even more than that when heavily loaded. Likewise, your 91W CPU can peak above that at times. And if you have OC'ed anything, the load on the PSU can skyrocket. Gaming can sometimes be the most load-inducing software we run (depending on certain factors).

If the PSU is under powered or poor quality or both, it may shut down when over-loaded. It may also die, hopefully not taking something else out with it. Even an adequate PSU of good quality can age and fail. Was the GTX 980 the card that came with the PC?

Yeah

Well, the first thing you should do is open the case and see what the make and model of that PSU is. Let's make sure it is up to the task. Pre-built PC? Who built it?

Cyber power

shrublr :

OK, now I know the make. Can I bother you for the model number?

No because I already sent the PC in

Was this a Cyber Power built PC? Because their PSUs used to be crap. Can't say about today. They may have improved. But I still suspect you need a better/stronger PSU with a power hog like the GTX 980. Btw, I have a GTX 980 in one of my gaming PCs.

Yes, but I had the PSU replaced.

Btw just a random question is a 1060 as good as a 980?

The GTX 1060 6GB is darn close depending on the screen resolution you game at. Some would say better since the extra VRAM can make a difference in some games.

Bottom line: you probably can't tell the difference. And it does it using far less power.

What about 1080

GTX 1080 > GTX 1070 > GTX 1060 ≅ GTX 980
