[SOLVED] Should I replace my PSU ?

[AForceGaming]

I've been having this problem over these couple of years, the PC starts ; fans spin, LED lights, HHDs startup but no display at all and no POST beeps.

In the first signs of this problem it was fixable and sometimes the PC boots up and sometimes you had to manually detach the CMOS battery for a few minutes, but that's no longer working and the PC continues to not boot up or make any beeps.

I tested the monitor on other devices such as a laptop and another MSI PC, I also checked the DVI cable and it's working fine with other devices and when I plug it in my PCs GPU the monitor responds and goes black.

I unplugged every component then booted up, starting from the CMOS battery, the GPU, the CPU, the HDD, and the 2 sticks of RAM. But there's no different whatsoever.

The PC is old and has over a decade, so maybe the PSU is gone bad or damaged somehow, the lifespan of the PSU is 5-10 years, and my PC's age this years is 10 years old, so I suspect that the PSU is bad.

I also recently applied a new thermal paste for the CPU, if that's a concern.

The rig is pretty old, I got it in 2011 and that answers the PSU's age, althought, this is my setup :

Hipro HP-D3057F3R 300W

Over 50 years ago, when devices with that type of voltage switches were common, I did the same to a radio. It was totally destroyed.
Luckily electric devices with voltage switches like that aren't allowed to be sold in the EU since over a decade. I don't know about other regions.

Yeah why would they make a stupid desicion like this... It's still being sold in my country and a few other countries for sure
I call it SRS from now on ; Stupid Red Switch

I've found a lot of Hipro units in older Dell systems, and they probably could found elsewhere too. Should be okay as far as quality is concerned.

Even if the fuse didn't pop the damage should be only to the primary side of the PSU, which means your hardware is likely to be unaffected.

However, you would need another PSU to test your computer with to be sure. You should replace your PSU at this point regardless.

What are the full specs of your system?

Specs aren't that good for nowadays I use it to play CSGO and L4D2 or Minecraft and rarely other games:

I don't know, I was out of solutions...

Well it's a harsh lesson, but a lesson learned nonetheless. That's how you look at it. One important thing to take away from it, if a power supply has such a switch, it's bad quality. Good quality kit nowadays auto switches between 110v and 240v. if it doesn't do that, it's no good.

it wouldn't be that harsh if the motherboard and components turn out to be working tho

If I intentionally put my hand on the stove, I don't blame Whirlpool.

Well fingers crossed they do, I'm presuming you haven't tested them with a different power supply yet? You might get away with it, depends how much the power supply that blew up protected the system. But having twice as many volts would be pretty terminal is my guess. I'm curious, let us know.

UPDATE : Here are the images I took after removing the PSU and unscrewing it :

I'd replace the unit completely.

Aside from the general amount of dust I think I see a bulging cap and there is definitely some signs of a burned trace in the button left hand corner.

 

[AForceGaming]

Mind you, what were you thinking switching that voltage switch?

[UPDATE] I got the new PSU from the store and... well the good news is that the PC is unharmed from the incident but the bad news is that the display problem still persists and I need to troubleshoot it more I think + I think that the SATA power cable coming from the PSU doesn't fit in my HDD I dunno why maybe it needs more pressure or something

Thank god everything was alright, well, except the stupid display problem...again

[UPDATE ] I took th PC to a technician and the problem was fixed, it was a dead RAM stick and I got it replaced

After all that drama The odd thing is though that you said you took out the ram and nothing changed.

Yes I took both RAM sticks and booted with the two different slots but nothing happened, no beeps, nothing...
