Heyheyhey!

This is my first post on tom's! sucks that it has to be about my computer crapping out...

My computer's been turning off randomly when I play games. I had it running over night with nothing open and it was fine, but as soon as I load up a League of Legends game or play hearthstone for more then 10 minutes, my computer shuts off. I also have to turn the power supply off for a couple seconds, then turn them back on. Any suggestions?

- Graphics Card --> Nvidea Geforce GTX460
- CPU --> AMD FX-8120
- Motherboard --> ASUSTek M5A78L-M/USB3
- PSU --> Lepa G500M
10 GB of Ram

Both the motherboard and the CPU are less than a year old, and the PSU is brand new, installed yesterday (of this post). I've looked inside the computer and the motherboard looks fine; no black liquids or anything jutting out. Connections have all been tested as well. Anything would help!

Thanks

i think my card was overclocked by a bit. I just went into my bios and hit load default settings, is that okay or should i actually remove the battery of my motherboard?

-edit- i put myself into a bot game of league of legends, and i opened hearthstone in the other monitor. after about 15 minutes, my antisurges went off and my entire rig restarted. It either does that, or just turns off, and then i have to wait a couple seconds before turning on. I put all the BIOS settings back to default too.

I removed my motherboard battery and plugged it back in, fully resetting my bios. After about an hour, it randomly turned off again. I had to turn my power supply off and on again before my computer would start. Any suggestions?

Thanks for being awesome by the way, I really appreciate the help.

No problem. I'm here to help.
What we have to do now is determine what is causing this issue. Take out the graphics card and try running only the intergrated. Does the same problem happen? :bounce:
If it doesnt then get a new Graphics card. That shouldnt matter since yours is pretty outdated lol.
I would reccomend the PNY NVIDIA GeForce 770 OC Edition.
It is what I have :)

It may also be a PSU issue. Try taking out your PSU and and one fan and attach the fan to the PSU. Plug it into the wall, turn it on and the fan should spin. Leave it for some time. If it turns off still. Youve found your problem.

any chance that it could be the mobo?

-edit- i can't test the graphics card because the games won't start without them in. The PSU is literally brand new, so i don't think its that either. Is there a reason why my computer would just randomly turn off because of the graphics card?

It is possible, but very unlikely. Maybe it could be your motherboard? Does this only happen with games?
Still try to test all listed components like I told you. It could be the PSU still. Its being new does not mean that it could still not be problematic.

the last couple of dies i've had it on and it hasn't shut offf. It seems like only when i have two games running does my computer randomly click off. How do you suggest testing the gpu without running games or anything?

I'll try running the power supply and get back to you!

Cheers

so i ran it with just the motherboard and the fans on (sorry, don't know how to get just the fans) for about 2 hours or so. That and the fact that i've left it on for the last 2 days or so continuously makes me think that the psu's in okay shape. just the gpu left!

Alright. That and the motherboard perhaps. Even the memory could still be a valid issue since it only happens when you have 2 games running.
This is OS dependent but to test your GFX card got to Run (Start+R) and type dxdiag. Simply click on the 'Display' tab at the top and somewhere there there should be a 'test' button or something like that. Just play around ;)

alright i'll try that out. I was moving my computer back to a standing position and then it restarted on me. I probably bumped something, but a power supply surge was detected and my asus anti-surges went off according to my system. Should i be worried? :D

Also, there isn't a test button on my dxdiag so i can't use it to see what's going on. Should i download a gpu stress test?

oops misclicked. I switched out my mobo and cpu with my old ones, and it still turned off... I'll bring in my psu for a 600w today.

You think it could be a wiring problem?
