G3258 Build crashing

Ever Never · February 16, 2015

Hi, thank you for reading this. I just built a new computer a month ago.

Pentium G3258

Be Quiet Dark Rock 3 heatsink

4x Be Quiet 140mm fans (2x are hooked up to fan control and two are hooked up to the PSU via 7V)

1x Be Quiet 120mm fan

MSI 750ti OC Gaming GPU

MSI Gaming 5 mother board

1x hyperx fury 1333 10600 stick of memory

Corsair TX650W

Intel 730 SSD 480GB

Crucial M500 120GB SSD

Bitfenix Ghost case

Monster HDP 850G surge protector

I've been trying for a month now to over clock it. I updated the bios, downgraded the bios.... No matter what I set it at, all the way from 4.2 to 4.5 it inevitabley just straight cuts off eventually. It will work fine for several, several days and then all of a sudden just blacks out and dies. If it's the over clock that's wrong doesn't it just blue screen? And yes it has blue screened and I've gone through and found stable settings. But it even does this on stock settings with no over clocking turned on at all. When it does these black outs it won't even fully come back on. I'll turn it on and it'll sound like it's starting but the case lights never come on and it doesn't boot up. If I unplug one of the hard drives it will come back on and appears to have cleared the CMOS and everything has been set back to default. Could this be the PSU? GPU? Or maybe even the surge protector?

Also, the black out crashes happen when I'm gaming. It has yet to happen during basic usage.

I'd say either mobo or PSU issue if it occurs at stock speeds.

Try a different powersupply, that is most likely the issue.... If not, it is your motherboard.

Sorry I haven't followed up on this. It was the surge protector. A Monster HDP 850G. These things are constructed from word go to find reasons to shut off. Away from a basic TV setup, don't use it. Thank you all so much for the help!

It's likely the power supply giving a brown-out, or an oversurge, and your motherboard trying to protect your CPU. I'd check your wattage, make sure it's not crazy low, and if your power supply isn't from a trusted brand (XFX, Corsair, Thermaltake, Seasonic, etc.) then replace it immediately. Buying a potato to provide safe and stable power to your computer (Linus's quote) is like throwing it off a bridge. It will only live until it hits the pavement below.
