PC shuts off by itself

post #1 of 14
Thread Starter 
So I have a newly built PC and I have played games with it for a few days but today it suddenly shut off by itself while I was playing LOTRO. After shutting off, it turned back on but only stayed on for a few seconds and then it got shut off again. This continued until I pressed the power button in front of the case (not the power supply button).

When I got the PC work again, I looked at the GPU usage and temperature with MSI Afterburn while playing LOTRO. The GPU usage was pretty high and the temperature got up to 60 celsius. I have everything on stock clocks.

Here's my build:

Intel Core i5-2500K (stock)
ASRock P67 Pro3 B3
MSI GTX 560 Ti Twin Frozr II (stock)
G.Skill Ripjaws X 8GB 1600MHz (stock)
Samsung Spinpoint F3 1TB
XFX 550W Core Edition
Fractal Design Arc Midi

So where could the problem be? In the graphics card or where?

I'm not very experienced in the power supply field.. but did you make sure your current one could handle all of your hardware under load? If it's not power supply issues, I'd say double check your DRAM timings and such in the BIOS. Ensure that your memory is running at advertised timings and voltages, as well as speed (1600).

Have you checked the heatsinks to make sure they're positioned correctly and are secure? Did you use enough thermal paste on your CPU? I believe your PSU is enough to power those components, but you should double check here: http://extreme.outervision.com/psucalculatorlite.jsp

Keep us posted.

60c is very repectable for a GPU game load temp imho, you don't need to concern yourself with temps unless they exceed 80c with the 5xx series. The only reasoning behind it shutting down is either your CPU is getting toasty (thermal max) or the PSU isn't supply enough amperage on a given rail.

As this is a newly built PC i'd also suggest that u recheck ur power cables from ur PSU are well connected/have proper contact
1) From PSU to mobo 12 pin & 8pin/4pin
2) From PSU to GPU

Thanks for all the replies.

The power supply should be more than enough according to a lot of posts I read before getting this build. And this PC is actually built by the store, not by myself.

CPU-Z says that the DRAM Frequency is 798.2 MHz and the voltage is 1.5 V.

By the way, I forgot mention that the build also has Thermalright HR-02 Macho CPU cooler.

Mmm... I got similar problem back then in 2008 but the game was not LOTRO. I was still using Radeon HD 3650. I blame the card, ask for RMA, got the new one, and the problem is gone.

PSU might not be the problem. my system draw 500 under gaming load when my Radeon HD 6990 overclocked to 975MHz/6000MHz. GTX 560 Ti is far lower than that.

I need to bump this thread because my computer has started to do this again. Everything was fine for many weeks but this week it has begun to shut itself off suddenly after gaming for some hours. I haven't overclocked anything, so everything is still at stock clocks (the graphics card is factory overclocked though).

I have already done everything what has been suggested in this thread.

This could be your problem. I'd help, but I don't really understand the whole "rails" business myself. Hopefully someone who does will come by to help.

Did you change anything in your software environment or updated Forceware? Or this happens when you play certain games? New games?
