Something exploded when I turned on the power to my computer.

Please help me!!! When I was checking for the fans to work on my computer some batteries blew off, and three had their paper exposed and also an medium sized battery bloated. Please help.

Take pictures of what your speaking of please, hard to tell by your descriptions, as a computer only has one batterie (cmos).

Batteries or capacitors?

Either way it's not a good sign.

You have to replace the damaged components

You should list all your computer parts for more accurate advice, but what you are describing sounds like blown capacitors, and whatever device they are on (graphics card?..motherboard?..) is basically dead. You need to determine why that happened, tho it is likely a failed power supply. Replacing the faulty part without eliminating the cause could lead to the same result.

If it was a new component RMA it. If it was a used part you will have to buy a new one unless you are willing to do some dirty work.

As an earlier reply stated, you might want to replace your PSU as well as that could potentially cause it. (did you have your voltage switch on the proper voltage?)

For more help and in future posts, you need to add more detail such as a parts list, and pictures.
