Specs: Windows 7
I've just got a new computer and when i plugged it in it blew up- i mean went pop and blew smoke...and now it is dead- wont turn on.
Now I've noticed that the voltage switch was on 115 v instead of 230 v. This means that the computer has been majorly overloaded. Is this a blown power supply, motherboard, CPU?? can it be fixed, or is it 'bye bye computer!'?????

✔ Best Answer
Not Good... You said New, if it is truly new then it has a warranty so I would recommend trying to pursue that avenue first.
With the switch on the lower voltage, the power supply is almost positively fried, the question is whether any higher voltages leaked past the power supply to the motherboard and other components. The answer is possibly. With a cheap power supply, that possibility would be greater then with a better quality power supply. If it turns out that you have to repair the system or at least pay for the repair, I would first open up the system and give everything a good look over with a strong light to look for burnt or bulging components and don't underestimate your nose in deciding where the burnt parts are. If all visually looks good and the only place the smell is coming from is the power supply, I would try swapping in a good power supply and test the system.

You have to be a little bit crazy to keep you from going insane.

So you live in an area where the wall socket gives 230 volts?

The pop was probably the fuse blowing in the power supply. I suggest you first open up the power supply and check the fuse and replace if necessary (some soldering might be involved). Then hook up everything again, verify the voltage switch is correct and try it again. If you're lucky the fuse blowing prevented any damage. If you're not lucky, well it could be anything.
