Question about Computers & Internet

Without tools or other spare components/computers, how to troubleshoot ''dead'' Dell Dimension 4500? No beeps/fan, etc. Have taken off front cover and switch seems okay mechanically. Small green light on mobo is on, but no other lights/sounds. Have removed RAM, all drives, and all cards except graphics adapter, and still nothing, no monitor signal. If you say it is the PSU, why? How do I know it isn't the mobo or CPU? Thanks for your kind help!

Well, it's cheap enough to purchase a power supply tester and check the power supply first. This would be much cheaper and buying a power supply as opposed to a motherboard would be much cheaper. The power tester runs around 10 dollars at any hardware store. Usually if the power was working, you would at least see fans working and hard drive sound so that would be the first thing I checked is the power.

With case open, and power ON...
locate the two "power" pins that were connected to the power button cable that is on the front cover.
Find them and tempoarily "short" them with a metal thingy, like a paperclip, taking care not to touch any other components. If it starts or produces a beeping code, then put it all back together and make sure the power pins are properly connected.

If it doesn't work, then perhaps the 12 volt side of the power supply is out. The mobo LED is powered by the 5 volt side of the PS.

The 12 Volt side powers heavy things, like the hard drive motor, fans, cd drives, etc.
the 5 volt side if for the data bus or circuits.

The power supply may have several "legs" of cables. If so, use only one set to see if the system works; then the other.

I hope this helps and it works!

    The two power pins are on the motherboard, by the way.

    You probably knew that, but I just wanted to clarify my "solution"...

When I attempt to turn on computer it beeps but nothing happens.

You likely have an internal component failure or improperly seated memory module. It could also be caused by a faulty cable, such as a monitor cable, drive error, etc... You can reference this link to assist you in diagnosing the defective component based on the beep code. Beep codes or BIOS codes beep in different series of long & short beeps so that a defective component can more easily be identified.

Older dell desktop computer will not turn on, just beeps

Beeps are caused by No Video, CPU or Memory. The System could just be dirty and caused a loose connection in the Video Card or the Memory Module. Or a CPU Fan is dead.

I have a wireless card in my Dell Dimension

The first thing I would try would be to reset the card, by removing the cover (if you are comfortable), removing the card from the slot and reinserting in the slot or moving the card to another slot (if there is an identical slot). If that doesn't work, replace the wireless card either with another wireless card or a USB wireless network adapter (external adapter that connects to a USB port). Good luck.

My Dell Dimension 4500 won't start unless I take the cover off the hard drive and mess with the wires. Is it time to buy a new computer?

The green light means or is supposed to mean that the PSU is getting power and working properly. Unplug a few devices such as the CD drive and/or the Hard drives and see if the computer powers on. I have seen a fair number of Dell PSUs just fail, they keep putting out the right Voltages but they don't put out enough power anymore. Do you have a spare and comparable PSU lying around?
