Random shutdown when Gaming (Boots backup right away)

[fiji42nk]

I am currently running into some random shutdown issues which started a few weeks ago. I will be playing a game and the computer will instantly shut down without a BSOD. Once powered down a few seconds later it will start back up again and it usually boots no problem. It will sometimes try to power back on, fail after a second, and then power all the way through (sometimes it shuts off multiple times before loading properly).

I have tested out my temperatures (GPU gets very hot) with Furmark as well as a CPU test and I had no trouble running them for over 15 minutes each on full blast.

From what I can tell it seems my PSU is finally dying which explains the lack of BSOD and it failing to properly boot up some times. Any thoughts?

I would agree, if the Psu is a few years old say more than two, or three.

And the system has problems even loading in to windows and to the login page or desktop.
But also has to power cycle the system a few times to work right.

It is almost certainly the power supply unit of the system at fault.

All power supply`s degrade in stability and how many watts or amps they can produce over a few years of constant use.
And more often that just stopping working right off the bat one day, start to exhibit the exact symptoms you are seeing fiji42nk, getting more and more unstable.

So yes I would look into replacing it.

But also have a good clean out of your graphics card, for any dust build up since you mentioned it was running quiet hot.

Freezing is a common sign of driver or temp issues. Shutdowns are usually a failing / bad power supply. If you list your complete system specs a recommendation can be made for an appropriate model of good quality to replace yours.
