Default red blinking light on tower

a friend exchanged my computer for one he had and my printer is attached to it. It is downstairs with a monitor and upstairs i have a laptop that i use all the time. To print I need to have that other one on and now it just keeps blinking a red light. I turned off the switch for a few minutes and thought maybe it would go back to normal but when I hit the button to turn it on it flashed green and went to flashing red. Is this it or is ther something i can do.

More info please:

Brand and model of computer with the red light.

Is there a symbol on the case next to the offending light?

Does the computer boot at all? Anything on the screen?

We also need to know how many times it's blinking -- it will blink a certain number of times and then pause for about 2 or 3 seconds. Then it should blink again... Could be something really easy, could be a piece of hardware that needs replacing.

It's called a Compaq, and the blinking just goes on and on. Where the green light for on is, it's doing this red blinking thing. No I can't use the c omputer but I am fine with the laptop.

be sure to add the hardware provided by the printer onto the laptop. Typically the red flash will indicate that there is no known cpus within its area to recive requests from.

It could also be that the printer is out of ink, paper, or not properly put together.

Okay...that's like telling the mechanic "My car is a Ford, what's wrong with it?" The mechanic needs to know what kind of Ford it is.

You have a Compaq, but there are MANY different types and models. In order to tell you what the light means, we have to know what model the computer is. Even a serial number would help, just give us something to work with.

I'd venture to say the power supply on the computer is toast. Take the PC to a shop and have them test it.

Actually just saying it's a Compaq says quite a bit. Like most HP computers they just don't work right, which is why I gave my HP away. The last 2 HP computers I had, had a problem with the south bridge.

The only red light I know of is the HDD activity light. I'd unplug all the devices, CD, Hard Drive, Floppy, and see what happens. If it starts up and things pop up on the screen, then the power supply is getting weak.

I happen to actually do warranty service on a lot of HP computers. Different numbers of flashes can and do mean different things. Beeps along with the flashes mean things as well. So do any codes you might get if you can watch the POST sequence. He might have something as simple as an unplugged heatsink fan, or something as drastic as a deader mobo. Can't start pointing him in the right direction without at least minimal info.

You mean HER, right?

Why does everyone assume everyone is a guy?

Besides, if it is not powering up, you should try start with the bare minimum devices. If that doesn't even happen, then, you can rule it down to the motherboard or the power supply, test another power supply, if it doesn't power up still, that's when I'd say a dead board.

It's easier for me and more fun to try with NO info and work backwards. Then to think I have to know everything to get it working.
