My PC keeps turning off...please help

[Laeore]

You have a nice setup for a smooth PC I forgot to mention what OS are you running?

Thanks!

Windows 7 64bit and sometimes when I'm lazy I run games out of Fedora. If I saw anyone post random shutdowns, I'd definitely suggest power/heat issues, but I've ruled that out systematically. Its kind of annoying. The only common factor in the shutdowns is the FF14 game client.

Just to reiterate what people have been saying, never ever, ever, EVER skimp on a PSU. It's the most important component in your PC in that if it fails, it puts every single other component at risk of failure as well. If you have a cheap PSU, replace it.

It's your PSU aka Power Supply Unit that's defective

Further, if you are upgrading a store-bought PC with new parts, upgrade the PSU too. Store-bought, even among gaming rigs, tends to go with what works well with the original build making future upgrades more than just a swap job.

ontop of these suggestions it could even be the motherboard itself overheating or a bad connection with it. I'd try disconnecting some parts of the computer that are not neccessary to the bootup of the machine and see if it stays on for longer (ie, extra hard-drives and optical drives, or even your graphics card if your MB has backup.). If it stays on longer its the PSU, if not its likely the MB

Check your power supply. You're overheating.

Why only FFXIV trigger? Because it's resource heavy and turn your machine to a furnace! This happens when I run most MMORPG for too long.

JustinLovesIzzy, sorry, no solution here but wanted to say that I had the same thing about a week after installing FF14. Out of the blue, the computer would kick me right out and restart. I tried the drivers as well, update, uninstall, reinstall etc. Nothing worked for me. Sometimes I could play an entire evening and sometimes it was impossible to play due to the restarts. I have a Geforce GTX 680 by the way.
To this day I am not even sure what fixed it, all I know, there were a couple driver updates through the Nvidia Control Panel and at one point in time it just stopped restarting. Some time back I experienced the same thing when I installed Minecraft. Same card, computer started to act up with restarts even outside of the game. I uninstalled it and it worked fine after that.
So far everything works fine for me, knock on wood.. Hope you figure yours out soon.

I had a similar problem like yours. PC would shut off only during gaming sessions. Temperature monitoring software showed that nothing was overheating. Power supply (not a cheap one either!) was still under warranty so I replaced it. That didn't help either.

The culprit turned out to be a bad stick of RAM. If you have multiple sticks, take one out. Play the game for a while and see if the problem persists. If it still does, put that one back in and take out the other(s) and repeat. It seems like my problem was a much rarer occurrence than having a Power supply failing, or overheating... but hey, it happened to me.

More than likely its your CPU overheating, when upgrading a new GPU nowadays more than likely since modern GPU create so much heat you need liquid cooling over your CPU.
You must worry about CPU's temp and GPU temp in modern day PC gaming. CPU overheating sounds like your issue. other issue might be new tech not compatible with motherboard ( if it's and older model) or not compatible with your power supply. GPU are touchy their requirements for power and the right environments are high.

the reason why you are shutting off while playing is because that is when your GPU really turns on. Nvidia knows when and how to use the GPU's resources and when not too. The power it uses to run normal OS and software is much smaller than when running a graphically complicated game. It's turning your PC tower into an oven.

Bad power supply or mobo, or maybe unstable overclock. If overclocked reset everything to stock. Test the PSU by unhooking all components and jump start it with a paperclip between the green wire and any black wire of the main connector and just let it run. If it shuts off after a while there's the problem. If not maybe it's mobo.

You could also keep an eye on CPU temps with software that has an audible alarm if it gets too hot. I doubt CPU overheating is the issue though because most CPU nowadays just throttle themselves back when too hot instead of shutting down completely.
