PC Powers Off Suddenly

The Sentinel · Apr 26, 2014

Hi,

I have recently noticed that my PC powers down and tries to reboot again and again (not shuts down, it just completely turns off as though something tripped). So initially thought that the CPU and MOBO power connectors might be loose, so I reattached them. Thereon after, I was gaming and decided to stop, so I exited the program and then it hits me again, just completely shuts of and tries to reboot again and again.

Everything's fine now after I reattached the Mobo power and CPU power. I checked Speedfan and realised everything's running cool. Is something amiss? or is the PSU failing? My worries is that the PSU is the issue, it's less than 3 months old! Or could it just be a loose power connector because everything seems fine as i type this.....

My Relatively New Build Specs:
Intel I5 4670K
Asus B85ME Mobo
MSI R9 270
Crosair 750W PSU

Thanks for helping!

If it works fine than occasionally messes up, it could be that you are receiving dirty power. Do you live in any sort of shared housing? Like an apartment or mobile park? They usually have problems like this.

That's what I assumed, but the PSU is connected to a surge protector and the other electronics worked seemingly fine during the occurrence so I don't think the power grid is the issue though. Thanks.

No problem! Try plugging the computer into a single separate outlet of it's own. See if that helps any.

An outlet on a different wall to be more specific.

After much time, my PC did the same thing again. I did some research and found out that maybe my IO Shield is causing the problem, when I was connecting a keyboard to the backpanel, the PC shorted out. Very peculiar, could this be the issue? Also this may be insignificant but I ripped the foil cushion on the IO shield to get a better fit upon first installation so could it be the cause of the problem, any ideas?
I will run the system without the IO shield in the next few days while awaiting a new one.
Or could this be also resultant of loose connectors? (cpu, mobo power connectors)

Thanks for helping!
