AVR suddenly made static/electrical noises, then PC shuts down and won't turn on again?

Started the day like any other and then suddenly my AVR made this static/electrical noise then my PC shuts down and cannot be turned on again.

As of now I haven't tried anything YET as I lack knowledge towards these voltage and AVR stuffs. With that in mind, I will be cautious as to not cause any unwanted damages, and will only follow anyone's advice in this thread.

I'm afraid to find out if the damage is spread throughout all the components (assuming there are damages), in which I hope is only limited to the power supply. Everything was running fine for 4 months now since my last changes towards the GPU and motherboard only, while the AVR has been around for 3 years minimum. Haven't checked the internal parts of the PC as this may possibly just be an AVR problem that calls for an AVR change. As of now I'm only giving the PC and AVR some time to cool off while I wait for answers, which made me realize that I NEVER turn off the AVR, if that helps.

On the sidenote, I will be updating any additional info here from time to time regarding this matter.

Setup:

Don't judge me 🙁
TX 650W
AMD Phenom II x4 965BE
MSI 970 Gaming
MSI GTX 1060 6gb

Oh, and a belated merry Christmas for everyone, cheers.
 
Solution
According to research, it seems an AVR is quite the necessity in the Philippines due to massive inrush current after brown/blackouts etc. As such, this'll be the first (and only) line of defense for your pc. Not knowing the exact product just leaves most at speculation, but I'd like to think it did the job intended and protected the pc. Now whether it was too much of a spike and overloaded the AVR or not enough of a spike and bypassed the AVR is anyone's guess. It might be that that particular outlet on the AVR will no longer handle a high load, I'd plug in a hair dryer and test it for that. I'd also plug in the pc directly to the wall in a test, just to see if the pc works. If the pc doesn't work, the psu is suspect, if it does then...
Not being up on all lingo, I'm assuming your reference to an AVR is uninteruptible power supply? Or a plug strip of some sort? Being that, just unplug all of it a plug the pc directly to the wall. If anything is fried, you'll not make it worse, and hopefully the pc is good. That TX is definitely dated, has minimum protections, but those, hopefully, will be good enough. The AVR is already suspect, I test everything with a heat gun (paint stripping hair dryer) which is not only highly portable, but puts over 10A load on things. If the AVR can handle that, chances are good that the psu is probably bunk. As to further component damage, that's not possible to determine until you get solid power to the pc.
 


An automatic voltage regulator, with an Akari brand to be specific. I tested the AVR with other components and they seem fine. So if the power supply is the culprit or the PC itself in general, what would the static sound coming from the AVR mean? Perhaps the PC demanded too much power the AVR couldn't give?

So I guess I need to replace the PSU and maybe a new AVR?

You won't be able to figure out further possible damages (if any) until you figure a reliable power source. If you had access to a separate psu, that would be great to start with.
