Computer Tech question

I dont get this

I left for a friend\'s house earlier today and I shut down my pc and when i came home tonight and booted my pc up my light that shows the comp is on was a solid green and now it is a solid yellow color. I dont think any of my brothers friends could of done anything because I had  Bios password on the comp before i left

Can anyone help to why it changed colours? does it mean anything??

It means the computer is still on but it is in sleep mode. That means it is semi-powered which is good because everytime you turn it off and on it damages it a bit. If you have a BIOS password on someone probably tried to turn it on and couldn\'t do anything so after a while the computer went into sleep mode.

hmmm maybe the small light bulb turned a diff shade or even worse, your computer is being attacked by millions of technology eating bugs and its slowly eating away the inner area of your comp.

Oh is that it shingoku?

whew thats a load off, I thought it was something serious
