PSU on the blink? Or something else?

Hey guys,

Just did a fresh install of windows as my old HDD didn't seem to power up on Boot all the time even though the other drives were fine (I tested them all one by one to be sure).

Now when playing games sometimes the fans will go to 100%, the screen will go black and then PC will reboot.

The PSU is only just 2 years old and has been faultless till now.

I had the same thing happen on my old sesonic unit one of the power cables had melted on the psu end, something for you to check.

Thanks will have a look,

It hasn't done it for a few days but the fan seems to spin up to 100% every 10 seconds or so. I have made sure the case is dust free and the office is normal room temp.
