    On the motherboard there is an Auxiliary 12 Volt Power Connector, Did you plug this power cable into it? (4-pin ATX +12 Volt power cable) Are you Sure the ram memory is seated tight? Best thing to do is to remove the ram memory module/s, ('Sticks'), and reinstall them/it to be sure. Did you follow Ant-Static Precautions? Why is the thought that the motherboard needs to be replaced? Post in a Comment.

Was this also the original problem pedro1952?

Computer doesn't start up?

Removed Ram Memory, and no BIOS Beep Code/s.
Shouldn't have been. Ram Memory needs to be in there.

You press the Power On button. This in turn presses against a Power On switch, located within the plastic Power On button.

When the Power Supply is plugged into power, there is a 5 Volt Standby power, present in the Power Supply.

Pressing the Power On switch closes a circuit, that directs the 5 Volt Standby power to the Power Supply.

This excites the Power Supply, and turns the Power Supply on. (No don't go there, lol)
The Power Supply directs power to the motherboard.

The first chip to receive power is the BIOS chip.
(Chip and Chipset are slang terms for I.C.
Integrated Circuit, )

The BIOS program is 'burned' into the BIOS chip.

BIOS looks to see what devices are installed, DOES a Ram Memory count, TURNS the Processor on, and hands the computer over to the Operating System.
(Windows XP is one example of an O/S)

Unless you KNOW the motherboard is bad, I suggest you check the voltage power rails of the Power Supply, for the correct voltages.

[Unless you KNOW the motherboard is bad. One case in point, is that you have observed bad Electrolytic Capacitors on the motherboard. If this is true, then yes, it's obvious the motherboard is bad.

To expound:

A) ]

Unless you know for a fact that the motherboard is bad, I suggest your Power Supply is bad. Weak Voltage power rail.
Not enough power to turn the Processor on.

Your Power Supply is rated in Wattage.
(Voltage times Amperage = Wattage)

If this is in reference to a Gateway GT5058, it comes with a 300 Watt power supply.

Gateway Support > GT5058 desktop computer > Support Documents,

(In the main menu shown, left-click on Components.
Scroll down to the heading - Power Supplies)

1) ALL the LED lights use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts

3) A typical Processor uses 51 to 125 Watts. Depends on what Processor it is, as to how much Wattage it will use, at maximum operating capacity.

The Gateway GT5058 comes with an AMD Athlon 64 X2 3800+,
(In the main menu left-click on - Specifications)

Uses a Socket 939 processor socket.
(Components >Motherboards > Specifications > CPU Support)

The AMD Athlon 64 X2 3800+ may use up to 89 Watts. (That uses a Socket 939 processor socket)

Power for LED lights, plus perhaps spin fans a few times, but isn't enough to turn the Processor on.

This is why you can connect the optical drives, with the 24-pin ATX main power cable unconnected, and they have enough power to open and close, and the LED lights, light.

You plug the 24-pin ATX main power cable back in, and you are providing power for the Processor.

There isn't enough power for the Processor, and especially not enough for the optical drives, AND the Processor at the same time.

The Processor is 'stealing' all of the power. Not enough power to open and close the optical drive tray's, or even light the LED lights.

No Processor operating, there isn't anything to search for the boot sector on the Harddrive.

The harddrive may not have enough power either, to spin the Platters inside.

Have a cheap multimeter? Just need an economical one for this test. ($5 to $10)
You will be testing the 12 Volt power rail.
11 to 13 Volts indicates a good Power Supply
Less than 11 Volts indicates replace the Power Supply.

If not, is there a KNOWN to be Good, Compatible power supply, in an unused computer available?

KNOWN to be good.
Not one out of an old computer, that you have no idea if it's any good.

Has to have the correct power cables, and the correct amount of power cables.

How do I check to see if the power supply is working?

The front of your computer is the Front Panel.

The area of contact pins on the motherboard, that the main wires of the Front Panel go to; is the Front Panel header.

JFP1 is Junction Front Panel 1.
Better method IMHO is to state as Front Panel - Junction 1, so it's easier to understand.

Just some 'trivia' that I thought I would post to you.

Would however like to post;

Anti-Static Precautions

Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.
Relieve your body of Static BEFORE reaching inside your computer.

(The Static? More than likely you won't see it, or feel it.
Your computer will,.....POOF! )

Computer ON a table, computer Unplugged from power, computer case open;
TOUCH an unpainted surface of the metal frame of the open computer case.
This action will relieve your body of Static.

IF you leave your computer in the middle of working on it, be SURE to Touch the metal case upon your return.

Since I'm here;

The method to test if the problem is the Power On switch, or the Power Supply; is to use a jumper wire on the 24-pin ATX main power wire's connector,

This is an example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,

A jumper wire is used to BRIEFLY connect the Green wire, to ANY Black wire.
The Green wire is the Soft Power On wire. Abbreviated as PS_ON.

ANY Black wire you see is a Ground wire.
(And that goes for ANYWHERE in the computer)

The preferred jumper wire is a straightened out paperclip.
It is bent into a U-shape. Turn it upside down, and that is how it's used.
The top is wrapped a few times with black plastic electrical tape.
This taped area is for your fingers, and thumb to hold onto.
The 'legs' that come down on each side, are what is used.

One leg slides down, into the back of the ATX main power cable's connector, into the socket hole with the Green wire in it.
[The BACK of the connector is where the wires go in ]

Slides down RIGHT NEXT TO the green insulation of the wire, and goes down in far enough, to touch a female metal terminal.

All wires going into the 24-pin ATX main power cable's connector, end in this style of female metal terminal,

Looking at the middle photo of the Playtool link, you can barely see the openings of the female metal terminal connectors.
They look like small brass rings.

The other 'leg' of the U-shaped jumper wire, goes down into a socket hole, with ANY Black wire in it.

24-pin ATX main power cable is plugged in, just like the photo to the Right, in the Playtool link.
Power Supply plugged into power.

U-shaped jumper wire is used Briefly. No more than 2 seconds.
[The Power On Switch is a Momentary Contact Switch ]

What is the Voltage involved in the Soft Power On circuit?
5 Volts DC.
In comparison two D cell flashlight batteries produce 3 Volts DC.

Just want you to know, so you won't think I could lead you into being Shocked.
Not saying there won't be a small spark, though.
You may wish to wear a glove on the 'jumper wire hand'.

IF the Power Supply comes on, you have a bad Power On switch.
(You noticed before that, but this would have led you right to it)

IF the Power Supply does NOT come on, you have a bad Power Supply.

Going further;
The Power Supply in your computer is an SMPS.
Switched-Mode Power Supply,

Another widely used term for Power Supply is the abbreviation
PSU. Power Supply Unit.

It converts the dangerous high AC voltage, 100 to 240 Volts, from your home or business; into 3 low DC Voltages.
The dangerous voltage is contained IN the metal case of the Power Supply.

The 3 low DC Voltages are;
A) 3.3 Volts DC
B) 5 Volts DC
C) 12 Volts DC

Gateway Support > Gateway GT5056 Desktop PC > Main Support page,

In the list click on Components,

In the list go to the bold black subheading -> Motherboards
Click on the blue title ->
105552 - Foxconn C51GU01Motherboard

On this page click on -> Product Views

Now you can see where every cable goes on the motherboard.
Let's take -> Q - Front Panel Connector, for an example,

Now you can see where every wire goes on the Front Panel header,

I don't know the color code of the twisted wires, that come from the Front Panel.
If -> I had to trace them, I would remove the Front Panel, and trace them to the;
A) Power On switch (PWR SW, or simply SW)
B) Power On LED (Light) (PWR LED)
C) Reset switch, (IF used) (RST SW)
D) HarDDrive activity LED (Light) (HDD LED)

If I were a betting man, I would bet the Red and White twisted pair of wires went to Pins 6 and 8. Power On switch.

Blue and White twisted pair of wires to the Power On LED. (Light)
Pins 2 and 4.

For additional questions please post in a Comment.

[I know. There's 5 minutes of your life you'll never get back.
I just posted the above, in case you run into this problem someday, and it isn't a loose Front Panel wire ]

Gateway dx4300

One of two possibilities; the Motherboard or power supply. In my case it was the Motherboard. Those cheap capacitors tend to go bad over time without being used. I purchased a replacement motherboard(Foxconn RS 780 "bengal") from a place in WI. Skyline on Ebay. I would do a search on Ebay for Gateway Foxconn Bengal RS780 Motherboard. Then get the number and call. You can use the old processor, ram, and maybe the graphics card, but I'd run the onboard graphics first(if you do happen to have replaced the motherboard) to make sure the graphics card isn't causing an issue. You will need to do some research and reading on the net about installing new motherboards and hardware. If the motherboard is the same, Windows should still work with it. Do your homework first as this is only a suggestion as to your problem. It is what happened to my Gateway DX4300-03. Check all power supply related, graphics card and wire connections first before you consider the motherboard thing.

Gateway Foxconn C51GU01 (105552) Problem: blue

Possible a memory socket is bad. Make sure you are using the correct type of memory including parity and compatible speeds. It is recommended to use like memory sticks in each slot. Some PCs even require the sticks to be equal memory capacity. User's guide should tell you what the compatible capacities and speeds should be. If you don't have the manual, you can get by looking up your PC model number on

I need the small original bios file (.bin) for my GM5084.

I would not despair yet, Bill. I suggest you go to the Gateway site again and locate the correct BIOS file for your system. If this is a file that you burn into your BIOS after booting with a floppy disk with an OS on it, then you should be Ok. Just follow the instructions.
However, if this utility can be run from your OS, then I would pursue the option you're after on this posting.

Of course it would be a great improvement, but unfortunatelly you can't install DDR2 in DDR slots, they are different and even if you could make it fit they have a big difference in architecture.

I supose you should test the capasitors one by one.

Faulty capacitors :

if the capacitors arent flat they are possibly bad note in the picture the blue / black capacitors are flat. the black orange capacitors all seem bad. the two are bad for sure.
