Wanted Thread! Possible PSU Failure Question.

[Shanemeister93]

Hi all,

I have noticed an issue with my PC over the past few day, when I boot her up for the day.

Basically when I start it up it'll fire up then all will shut off within the first second or 2 including the case fans, then it would instantly come back on and then is fine for the rest of the day and works without any issues ( I leave it on all day).

So my question is that if my suspicion is correct, am I right in thinking that my PSU is starting to die on me? Also unfortunately enough for me I don't have a spare PSU to hand.

Cheers Shane

Most common causes of the couple of seconds power on, then off are:

- Not all RAM sticks being seated correctly

- A PSU connector that has come loose (the one/two in your GPU, 24 pin Motherboard, CPU, and SATA into your HDD)

- GPU not being seated correctly

Check to see if any of those are an issue, if not, try moving your RAM about.

It does seem odd that it works fine the second time around, but I am not too sure.

Sorry for the late reply been afk all day, and everything is actually seated correctly and has been since I built the system in late 2013 early 2014 and has not been touched since, other than to put an uprated cooler in. even then I checked to see if everything was seated correctly and it was.

A slightly unstable OC can cause this as well

Sounds like memory training tbh.

Had this for years on a sabertooth board. Sold the system and it still does it on a different psu different case etc.

Pretty sure its a bios problem prob memory training as above. Dont worry about it!
