I'm not an expert when it comes to hardware. I was just on my computer (not this one), and it turned itself off. So I tried to turn it back on, and a blue spark pops out the back... Anyone know what is wrong and what I need to do...?!

blue sparks are never good. Sounds like you might have a faulty power supply. Remove the power supply from the PC and have an experienced electician give it a once over. Turning it on again may destroy your PC / yourself...

Most probably your power supply is fried.
You'd be lucky if it's just a defective power chord.
- Unplug the power chord from the wall socket.
- Check if the power line is plugged in correctly on the computer side.
- Check the power chord. If it is charred, its isolation defective or some other visible defect, your computer may have survived and could possibly work again with a new power chord. But it could very well have suffered damage as well, so having it checked would still be advisable (risk of fire!).
- If none of the above is true, the power supply is almost certainly fried and you definitely need to get professional service for your computer.
Do not leave the computer connected to the power outlet if it could be defective!!!
There is a risk of fire in the worst case. Don't take any chances!

Quoting AirbusA346 (Reply 11): Try and find out what is currently in the back of your computer and get the same Wattage.
I wouldnt worry about that as long as its higher wattage than what he has...and it looks like he has a 350W standard ATX power supply. A higher watt power supply will just support more devices (IDE, Serial, USB etc)
Power supplies are cheap, you can pick one up for $20 or 12 pounds.

The wire of the fuse inside your computer just got partly turned into atoms and got itself sprayed onto the inside of the glass fuse. The ionised air conducted electricity for a brief period and caused the flash. Sometimes this is accompanied by a loud pop as the glass breaks under gas pressure.
