Uuuh.. is my computer supposed to smell like metal?... that's being melted?... (Rhetorical question,)

I've noticed that that only way to wake my computer from sleep mode is to press the restart button, or the on/off button (Both which actually wake it from the sleep, it keeps everything open,). One thing I've also noticed, is that the back of the computer smells like burning metal, mostly around the On/Off switch, which is right next to the wire that connects the computer to a power outlet.

What do I do? ._. My Dad also noticed the smell, he said it smelt like fire. Do I try and replace the computer itself? Or what?

There are a few things that's wrong with my computer, which I've noticed that happened RIGHT after the burning smell began to happen:

• Audio jack doesn't work properly, only one side plays properly, and the other side has a buzzing noise. (And it's not the headphones, I put the same headphones into my 3DS, and both sides were working perfectly.)
• Not waking from sleep mode with my keyboard or mouse properly. (Okay, kinda a lie, it turns on, but when it's on, and I click with the mouse, the mouse turns on for a second, and turns back off. Also the screen stays black,)
• Headphones sometimes not working, even when plugged in.

So... anyone have any clue what's going on?
