If the wire is coming from the front bezel of the computer it sounds like your front panel connections. They connect to the motherboard and control your power button and lights. That would explain why it won't power on too! Unfortunately all motherboard connect to the front in different places, but it will always be on the outer edge of the board usually near the bottom of the tower. Try seeing which pins on the board match up. Hope this helps!

How to setup a Wireless Network


1. <b>Connect Your Wireless Router</b> <br /><b>a.</b> Power off your cable modem and your wired PC.<br /><b>b.</b> Unplug the Ethernet cable from your cable/DSL modem and plug it into one of the LAN ports on the back of the wireless router. Leave other end of the cable connected to your PC.<br /><b>c.</b> Connect another Ethernet cable between your modem's Ethernet port and the wireless router's WAN port. (The WAN port should be separate from the other grouped LAN ports.)<br /><b>d.</b> Power on the modem and watch for the status lights to indicate that it's connected to your Internet service. This may take a minute or so.<br /><b>e.</b> Plug in the router. The status lights will blink as it runs through its diagnostics; this may also take a minute or so.<br /><b>f.</b> Start up your wired PC.<br />2. <b>Configure your Wireless Router</b><br /><b>a.</b> Refer to the router's quick-start guide, launch Internet Explorer, and type in the address indicated in the guide.<br /><b>b.</b> Follow the on-screen setup wizard, which will guide you through the process step by step.<br /><b>c.</b> Enable your router's security functions. This is very important if you don't want other people attaching to your wireless signal. The options will be WEP and WPA. Both will ask you to enter a key. Depending on the router's manufacturer, you may have to go into Advanced Settings to accomplish this step.<br /><b>d.</b> Change the default administrator's password, Almost all hackers know them.<br /><b>e.</b> Change the SSID-the name of your wireless network. Again, hackers know many of the default SSIDs and can use them to hack your network.<br />3. <b>Install a Wireless PCI Card in a Desktop PC</b> <br /><b>a.</b> Refer to the card manufacturer's quick-start guide. If necessary, run the software installation program.<br /><b>b.</b> Power down the PC.<br /><b>c.</b> Remove the cover.<br /><b>d.</b> Find an available PCI slot and remove the slot cover from the back of the PC.<br /><b>e.</b> Carefully insert the antenna through the open slot in the back of the PC, carefully push the card in the slot, and secure it. Replace the cover. <br /><b>f.</b> Start up the PC. It should recognize and install the new PCI card.<br /><b>g.</b> Go to the Control Panel, select Network connections, select Wireless Networking connection. Click on Properties button. Click on Wireless Networking tab. Select the wireless networking name (see step 2e). Click on Configure button. Configure your security settings to match the ones on your wireless router.<br />4. <b>Install a Wireless PC Card in a Notebook PC</b> <br />Many notebooks have built-in wireless cards. However, If yours doesn't, you can install either a USB wireless adapter or a wireless PC card just follow these instructions.<br /><b>a.</b> Refer to the card manufacturer's quick-start guide. If necessary, run the software installation program.<br /><b>b.</b> Power down the PC.<br /><b>c.</b> Plug your USB wireless Adapter or wireless PC Card into an available slot on the side of your notebook.<br /><b>d</b>. Start up the PC. It should recognize and install the new PCI card.<br /><b>e</b>. Go to the Control Panel, select Network connections, select Wireless Networking connection. Click on Properties button. Click on Wireless Networking tab. Select the wireless networking name (see step 2e). Click on Configure button. Configure your security settings to match the ones on your wireless router. well, thats pretty much it. Hope this is helpful to all you home networkers.<br />

Can a speaker be internally installed


Shut the computer down completely if you are installing a PC speaker in a computer that you have already built.

Disconnect the power cable, and bring the PC case to a sturdy table or workbench.


Open the PC case.

A PC case sometimes has a release lever that you can use to slide the cover off without tools.


If your case has no release lever, look for a series of Phillips-head screws on the back and remove them before sliding the cover off of the case.


After removing the cover, place the case on its side so you can access the motherboard.

Locate the connector for the PC speaker near the front of the case.


Generally, the connector has two wires black and red and a black connector with four holes on the end.


Examine the black connector, and note the hole a dot or arrow next to it.

This end of the connector should align with pin 1 on the motherboard.


Look for a bank of pins on the motherboard, near the front of the PC case.

Near the bank of pins, there should be a guide explaining the purpose of each section of pins. Examine the guide to find the four pins labeled "SPK," "SPEAKER" or similar.


Place the connector over the four corresponding pins so that the side of the connector marked with an arrow or dot goes over the pin marked "1."


Hope this helps

Blinking amber power light pc will not turn on replaced power supply


Out of Dell's Dimension 2400 User Guide, the 2350 user guide doesn't list it;

"If The Power Light Is Blinking Amber - A device may be malfunctioning or incorrectly installed

1) Remove and reinstall the Memory modules."


From me;
Ram memory modules. Slang? Ram memory stick.
I would suggest cleaning the gold plated contact pins, on the bottom of all ram memory modules, then reinstalling.

Use a pencil eraser.
If using the eraser on the end of the pencil, and not a solid eraser, refrain from touching the gold plated contact pins with the metal band.


Handle the ram memory module by the Body of the module. Refrain from touching the contact pins.

[ The Body is everywhere but the contact pins themselves. The body of the module is coated with a see-through protective plastic,

http://en.wikipedia.org/wiki/File:Generic_DDR_Memory_%28Xytram%29.jpg

{ The Dimension 2350 Desktop PC uses DDR Sdram ram memory, at 266MegaHertz. Or also stated as PC2100. The above example in the link for DDR Sdram above, just happens to be PC2100 ]

Rub each contact with the eraser, both sides. Doesn't take much to clean the surface.
{Doesn't take much 'corrosion' to make a bad contact, either }

Use air to remove the eraser dust.


" 2) Remove and reinstall any cards."

From me;
Cards being any adapter card OTHER than the graphics card. Any adapter cards in a PCI slot.
(For the Dimension 2350 )

"3) Remove and reinstall the graphics card, if applicable"

From me;
If applicable. Means IF there IS a graphics card installed.

Plus for the Dimension 2350, a graphics card will be installed in one of those three white PCI slots.

I have seen a PCI slot burn. I have also seen where the PCI slot was bad, but showed no outward visual signs of damage. Solution was to use a different, available PCI slot.
By the time this is all going on though, the board should be scrapped. (Mobo)

What do the Electrolytic Capacitors on the motherboard look like? Show any outward visual signs of failure?

http://www.capacitorlab.com/visible-failures/index.htm

Plus, just to be sure have you tested the voltages of the new Power Supply?

Isn't actually an accurate test, but if voltages alone aren't what they're supposed to be, the PSU is bad.
(Accurate test is the Power Supply is under a load, then the voltages are tested )

3.3 Volt power rail, (Orange wires), 5 Volt power rail, (Red wires), 12 Volt power rail, (Yellow wires)

Test with a multimeter set to DC voltage. (Function knob set to DC voltage. May be just a DC Voltage symbol. Dotted line over solid line. If there is more than one setting, set it to the 0-50 Volt scale )
An economical multimeter can be purchased for around $6 to $12.

Bad power supply's do get shipped. Doesn't matter if a power supply is new, it can be bad.

Power Supply power cables unplugged from motherboard, (And laid aside so that they are Not near any hardware components ), turn the Power Supply on. See if it at least stays on by itself.

[ Jumper to back of the 20-pin ATX main power cable connector. From Green wire socket hole, (Soft Power On wire), to ANY Black wire socket hole. ( ALL Black wires are Ground wires )

Make SURE the jumper wire goes down into the two socket holes, far enough down to touch the metal terminal connector, at the end of that wire.
Preferred jumper wire is a straightened out paper clip, bent into a U-shape, and the middle of the U-shape is wrapped with black plastic electrical tape.

But you probably know this, as you had to test whether the problem was the Power On switch, (ATX power on switch), or the Power Supply, before purchasing a new power supply.
{Or did you?}


No to all of the above? Power supply checks out?

Start removing Peripheral hardware components.
Optical drive/s first.
(Computer unplugged from power, Anti-Static Precautions observed )

Then the harddrive. You are just trying to see if the power supply will come on, and stay on, for now.

Ram memory.

If the power supply comes on, and stays on with a particular peripheral device removed, stop.
There is the problem.

How to install an wirless adapter to mi desktop


Install a wireless network adapterIn areas that are served by a wireless network, you can connect to a computer network without using a cable, and surf the Internet or connect with other computers. To connect to a wireless network, your computer needs a wireless network adapter.
Many new computers-especially laptops-come with wireless adapters. Before using your computer, check to see if it already has a wireless network adapter.
If your computer doesn't have a wireless network adapter, you can install one.
Install a wireless USB network adapter. Most people prefer this type of adapter for any type of computer, because it's easy to install.
Install a wireless CardBus or CF network adapter. For portable computers, this type of adapter (also called a PCMCIA or PC Card) is easier to travel with than a USB adapter, because it is often smaller and fits securely in the PC Card slot on the side of the computer.
Install a wireless internal network adapter. If you have a desktop computer, you may prefer an internal adapter so that you can use the USB port to connect another accessory.
The type of adapter you install depends on your computer and your level of expertise.
How to determine if you already have a wireless network adapterMany portable computers manufactured after 2000 have wireless networking built in. However, because the antenna is hidden inside the computer, it's not easy to see.
To see which network adapters are currently installed in your computer
1.
Click Start, and then click Control Panel.
69010-click-control-panel.gif 2.
Click Network and Internet Connections.
69010-click-network-and-internet-connections.gif 3.
Under or pick a Control Panel icon, click Network Connections.
69010-click-network-connections.gif 4.
Microsoft Windows XP displays your network adapters. Wireless network adapters are labeled Wireless Network Connection. If an adapter displays a red X, it is disconnected. If the Network Connections window is blank, your computer doesn't yet have a wired or wireless network adapter.

PC was caught in a lightning storm, and now will not boot (only at random). It seems like it's not getting power, when it does it'll boot normally. But when the storm hit my LAN was disabled and I had to...


Test whether it is the Power On switch, or the Power Supply. Since the LAN card bit the dust, you may be looking at a worse problem, though.

Bypass the Power On switch.

If the Power Supply comes on, the problem is the switch.
[One generic ATX Power On switch, that I have found fits many computers,

http://www.directron.com/atxswitch.html

If the Power Supply does not readily come on, the problem is the Power Supply.

To bypass the Power On switch, you will be using a jumper wire on the
24-pin ATX main power cable connector.

Looks like this,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

(Not necessarily the same color, and isn't located in the same position on your motherboard, as shown in the link)

Motherboard orientation:
Processor to the top, Ram Memory slots to the right.

The 24-pin ATX main power cable connector on the motherboard, is to the near right, of the number 4 Ram Memory slot.

In case you do not have the Owner's Manual, for your Inspiron 530 desktop computer,

http://support.dell.com/support/edocs/systems/inspd530/en/index.htm

On this page left-click on -
Owner's Manual - View - Download - (HTML 3.44MB)

Left-click on - Removing and Installing Parts
Left-click on - System Board Components
(System Board = Motherboard)

Number 7 - main power connector (ATX_POWER), is the
24-pin ATX main power cable connector, on your motherboard.

Referring back to the Playtool link, you will see a wire with Green insulation on it.
This is the Soft Power On wire. (PS_ON)

A jumper wire is used to connect it to ANY Black wire.
ALL Black wires are Ground wires.

[This is a DC circuit. There is a Positive, and a Negative.
A Ground wire is a Negative wire.

The green Soft Power On wire, is a positive wire containing 5 Volts.
You are completing a circuit.
The Soft Power On circuit.
You are bypassing the Power On switch]

There is no splicing of the wires to connect the jumper wire.
The jumper wire will go down into the socket holes, of the 24-pin ATX main power cable connector.

One end of the jumper wire goes down into the socket hole, containing the green Soft Power On wire.
The other end of the jumper wire goes down into a socket hole, with ANY Black wire.

The 24-pin ATX main power cable, is connected to the 24-pin ATX main power cable connector, on the motherboard.
Just as shown in the photo to the far right on the Playtool link.

The back of the 24-pin ATX main power cable's connector, is where the wires come in.
(The front of the power cable's connector is plugged into the motherboard)

I use a jumper wire that is approximately 3 inches long. (7.62cm)
An insulated wire. Both ends of the insulated wire are stripped of insulation, approximately 1/2 inch. (1.27cm)

One bare end of the jumper wire, goes down into the socket hole of the Green wire. Right next to the wire.
It has to go pretty far down in there.

At the end of each power wire, going into the 24-pin ATX main power cable connector, is a metal terminal pin. (Actually is a round hollow metal pin)
The jumper wire's bare end Must touch that metal pin.

The other end of the jumper wire, goes down into ANY socket hole with a Black wire.
(ALL Black wires are Ground wires)

Power Supply (Computer) plugged into power, the jumper wire is inserted.
The contact is a very BRIEF one. No more than 2 seconds.
(The Power On switch is a Momentary Contact Switch)

I suggest you also check the 12 Volt power rail. Check it with everything plugged in, inside the computer, and the computer on.
You need the Power Supply to have a load to get an accurate test.

There are 3 Voltage power rails in the Inspiron SMPS.
(Switched-Mode Power Supply, or just Power Supply for short)

A) The 3.3 Volt power rail
B) The 5 Volt power rail
C) The 12 Volt power rail.

The main one to check is the 12 Volt power rail.
[Orange wires are 3.3 Volt.
Red wires are 5 Volt.
Yellow wires are 12 Volt ]

The Positive (Red probe lead of the multimeter, is connected to any Yellow wire, coming out of the Power Supply.
The Negative (Black) probe lead of the multimeter, is connected to any Black (Ground) wire.

See if there is an unused standard 4-pin Peripheral power cable.
It has 1 Red wire, 1 Yellow wire, and two Black wires.
Connect to the Yellow wire, and to one of the Black wires.

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

[Multimeter function set to DC Volts. If it has it, set it to the 0 to 50 Volt scale]

11 to 13 Volts is Okay, but I prefer the voltage to closer to 12.
11 Volts indicates it's time for a new Power Supply.
