Look at the spec of the psu. The details will be printed on the device somewhere. You need to look for something like the voltage and current rating;

along the lines of:

Input 110v-220v
Output 12vDC
Current 5A

Then take yourself down to the nearest Radio Shack, or the like, (preferably with the dud PSU) and pick up one with the same, spec.
The critical part of the spec being the output voltage (12V) and a Minimum current of 5A. Also look for a little picture that tells you the layout of the output plug, normally looks like a dot within a capital C with a line to a + or - sign. (ensure that picture is identical).

I am making this post from Ruby's computer, to which I have hooked up my monitor. I set up my system, complete with my CRT monitor, and had it working (but, I did not have it hooked up to the internet). Then, I hooked up Ruby's monitor to my computer, and it did not display anything. Finally, I hooked my monitor up to Ruby's machine, and it worked.

I believe the problem is in the power supply to Ruby's monitor, which is a convert-to-12-volts system. The power light does not come on, on her monitor. So, perhaps I can stop by a computer repair shop and see if they have saved a power supply from a monitor that went bad, which they would sell me cheaply.

Unless it had been a matter of a loose connection, this is about as good an outcome as I could have expected.

The guy who build my 2003 machine is no longer in business at the location where I knew him, and I don't know where he has moved to. I might have some luck at Computer Recycler's, or at Retro-Tech.

Mr. Barnes has given a fine, complete account of what I need to check.

Leigh's remarks about the POST and the meaning of the beep or beeps (since I can't get info from the screen at this point) also ad to my information.

I recall that the drive activity light does show that the computer is active, even tho I see no display.

Why is monitor's screen blank when I start up my computer?


Answer: First, check if the monitor plugged in to a power outlet and is connected to the computer securely. Some monitors won't function even if the connection is slightly loose. If the monitor is connected correctly, make sure that the power button is on. If the power light is not glowing, the outlet may not be providing power to the monitor or the monitor may have a dead power supply.

If the power light is on and nothing comes up on the screen when you start your computer, it is possible you have a bad video card. Test the monitor on another computer to see if the display works with another video card. If it does, try starting up your computer in safe mode by holding down the F8 key as the computer boots up. This should solve any screen resolution or color setting conflicts that may prevent your monitor from displaying an image.

If the monitor is still blank when you start up in safe mode, you should open your computer (after unplugging it) and check to make sure your video card is seeded properly in the motherboard. If the video card is properly connected and the display still does not work, you will probably have to replace the video card in your computer. While high-end video cards can cost $500 or more, you can get a decent video card for about $100. Check you computer's manual to see if your computer uses a PCI or AGP video card before buying a new one.

If the monitor didn't work even when you connected it up to another machine, the monitor has probably gone bad. Check the cable to make sure it is not broken or frayed anywhere. Then make sure the pins on the connector aren't broken or bent either, as even one bad pin can cause the video connection to fail. If you have a CRT monitor, do not attempt to open the monitor, as it may store an electric charge powerful enough to electrocute you. Even if you have a flat-screen display, do not attempt to repair it yourself, as it does not have any user-serviceable parts. Instead, take the monitor in to your local computer repair shop and have them repair or replace it for you.

The first thing I'd check is all connections. Make sure the power point a)has power and b) is turned on. (I've been called out to a 'puter that wasn't plugged in before). Does the computer "beep" when you turn it on? (That, at least indicates P(ower) O(n) (S)elf (Test)). IF multiple beeps at POST, that will indicate a problem with the system unit. If only one beep, does the computer drive "activity" light flash? (That tells you that the computer is loading windoze). More information needed.

The fact that the monitor does not even power up suggests the problem lies with the monitor:(
Is it plugged in OK? Have you checked all the connections? Have you tried plugging it into a different socket?

On Ruby's computer, nothing is showing on the monitor--no picture displayed, not even an indication it is on (such as a power light (green) or standing-by light (yellow)

I picked a random monitor from my storage supplies of computer parts and plugged it into the computer to see if anything would show, and nothing appeared.

I'm considering the following possibilities:
--perhaps the power supply to Ruby's flat-screen monitor is not working
--perhaps the monitor itself has stopped working
--perhaps the graphics card (video card) in the computer, which was assembled for her by a best friend's husband who works on computers in his profession, has stopped working
--perhaps the video cable between the graphics card and the monitor has stopped working

My own desktop computer system was mothballed when we found we were both using Ruby's newer computer whenever we used the internet. I could assemble it again, and see if Ruby's monitor works on it. (Both computers use WinXP.) Also, after establishing that my monitor still works, I could hook it up to Ruby's computer and see if it displays when hooked up to her system. This could tell me if the problem is with her monitor, or with her computer.

What do you think and/or suggest? My computer monitor is the old CRT type.

I am typing this at the library.;)
