If you mean that you had the wrong voltage selected at the back of the computer(240/110V)...there is not much we can do to help.

Your power supply is severely damaged. At the very least that will need to be replaced, assuming that it has not fried the other components in your computer.

If you post details about your computer (Make, model) and any other details you might know (CPU, Graphics card, number of hard drives) we can try and suggest a replacement power unit.

However without physical diagnostic tools we can't determine how much of the computer is damaged.

Selecting the wrong voltage on the rear of your power supply will NOT damage the power supply. However, if you normally use 230VAC and switch to 115VAC you will damage at least your motherboard.

If your computer is still somewhat functional then you probably didn't damage anything.

Explain what you did do and what is happening.

Also post a model of your computer and the version of Windows you are using.

Where are you reading the message about 100 characters in the box?

Do not double post on the same topic. I removed your other post. Stick with this one.

If your scenario matches this guy then it is damaged:


230V through a power supply expecting 110V is going to damage something.

I have no idea what 110V would do to a power supply expecting 230V.

Here we use 230V, and anyone I have seen setting it to 110 has damaged the power supply in some way.

However if the computer still power's on then you are right, it is something else that is damaged.
