\015 My screen filled up with zig zag lines while on the internet. So I shut it down and tryed to turn it back on later and it won't come on. The light on the power button will not come on; but the fan comes on immediately when the power switch is turned on but then the switch won't turn it back off. The processor can be heard running also when turned on but nothing comes up on the monitor. Nothing goes off unless you unplug it. The disk drive will come in and out and there is a green light on the back of the tower beside the plug in that is on. Any ideas?\015
a few things you can try:
unhook the monitor from the computer and test it on another computer. If the monitor works then its most likely the motherboard.
leave the computer unplugged for a few hours then plug it back up and give it another try just in case it overheated.
have the computers power supply tested as a bad power supply can cause all sorts of issues.
other than that you are down to a new motherboard and or a new computer.

Volume Jerry I have it hooked up to the tower but there is an extra plug in that comes from the speaker itself; it says 12v dc, 1.0a on the speaker where this extra cord is. I looked at the screen that it originally came from and the screen has a plug in on it for this cord. the original screen is a Compaq and the tower is a Compaq, I have just upgraded the screen.
Oh i see the first question was way to vauge to really answer. it sounds that this is a powered speaker meaning it requires that 12v that you are reading and wont work without it. i am assuming that the cord coming from the speaker is a male end tha ... Compaq Presario 5000 PC Desktop
