Voltage Switch

[Xeqt]

Hey there, thanks in advance for reading my post. I flicked a switch on the back of my computer which unbeknown to me, changed the voltage. After a bang and a bit of smoke my computer stopped working. Could anyone advice me of what may have happened and what sort of job would it be to sort the problem out.

Hi Xeqt

Oh dear

 

Well unless I'm mistaken someone has altered the PSU to a different voltage.

 

Consider this picture here where it is set to 230v, if yours says 115v then oops.

 

This is like taking a box from America running at 115v and plugging it in over here without changing the switch.

 

This also could be considered as vice versa.

It sounds like the PSU is totally cooked and it may have taken the board with it.

I agree with Wolfey - try a new power supply, hopefully that should sort it.

 

If not, the mainboard will have been fried, and you will need to replace it.

 

It's also possible that the hard drive/CD drives has been over-volted. They are powered with 5 and 12 volts, and a quick zap of your power supply when set incorrectly may have fried those too.

 

Perhaps the best option would be to take it to a repair shop and ask them to go through and check all the components for you.
