PC Randomly Turning off

p0wp0w

Hi boardsies,

Looking for some help here - I initially thought it was the power supply.
Although, I haven't yet replaced it, I wanted to get some suggestions if there could be another possibility.

My PC just randomly turns off with no warning whatsoever while in use.
Even if I am doing nothing - i.e on the desktop - nothing CPU intensive.

Any suggestions on what to check before I go replacing the power supply?

Maybe its filthy inside. Take all stuff out, clean all the dust replace the cpu paste.

Then try to run it on integrated gpu if you have one or borrow new somewhere and check that, repeat with memory cpu and mobo till you find whats faulty.

My dad had a similar problem.
Open her up and look for a blown capacitor on the motherboard.

Look for any bulging or leaking, like this.

It does sound like it's your PSU. What make/ model is it?

had kind of skimped on the psu its about a yr old http://www.dabs.ie/products/best-value-alpine-500w-psu-120mm-red-fan-2-x-sata--pfc--78ZN.html

any recommended psu - pc not for gaming as such, running on board graphics bt nothing crazy.

Ouch, 14 euro for a PSU is asking for trouble. I'd recommend this, http://www.dabs.ie/products/corsair-430w-builder-series-cx-80--bronze-atx-power-supply-8BV9.html?src=3

BTW, Why did you go for a 2500k and Z68 motherboard if weren't using it for gaming?

Specific requirements related to PCI card clearance of cards that were used as a hack (ie not designed to be used on a desktop board) - no longer in use.

Other than that... no reason other than ... because I can.
