SOURCE: My Gateway GT5678 system powers up as if normal but no display.

When you say you tested the other components, did you test the graphics card in particular on another computer?

If so, and if it worked, you can try clearing the CMOS. There should be an easily identifiable switch or set of pins with a jumper. With the power cable unplugged, set the switch or move the jumper into the clearing position, leave for about 30 seconds, then move it back into position (important! do *not* power on the system while the jumper or switch is in the reset/clear position). Try booting up the system again.

If it now has a picture, you will probably need to enter the BIOS and, at the least, make a basic change such as setting the first boot device (defaults to the cd/dvd-drive, then the primary-channel+master hard drive).

If you still have no picture, and you are using on-board graphics only, then there is a chance that the on-board graphics chip may have died.

To test this, you can put a graphics card into the system (I recommend a cheap, second hand one that you know is working, in case the motherboard ends up damaging the card), repeat the CMOS clearing process, and then try booting up the system with the monitor plugged into the graphics card.

If you get a picture, there's a good chance the on-board graphics have died. You'll want to go disable the chip to prevent it from causing any further problems by finding it under the 'integrated peripherals' section of your BIOS. If it's not located there, search for an option for the 'primary graphics adaptor', and change it from IGP to PCI-E. Then find any option for 'vga memory share size', and see if you can set that to 0mb. If it is the model with the 2400XT with its own 256mb memory, you'll need to find an option to disable it entirely.

Please post a followup if none of the above was able to help you, with clarification if possible as to what you're using and have tried, and I'll see if I can help further.

SOURCE: Gateway Desktop gives me 3 long beeps

Sounds like Ram Memory failure.

Try removing the Ram memory modules ('Sticks'), and cleaning the contact pins with a pencil eraser. Corrosion can develop on the contact pins after a given time.

This isn't hard to do.

1) Computer unplugged from power, open the computer case.
(Unplug the power cord from the Surge protector, and NOT the back of the computer. {Power Supply)

2) Follow Anti-Static precautions BEFORE you reach inside your computer.

[Anti-Static Precautions:

Your body carries Static electricity.
Static WILL fry out (Short Circuit) the delicate hardware components inside a computer.

Computer unplugged from power, work on a table. Press the Power On button in, and hold it in for a count of 10 seconds. (To relieve any residual power)

Computer case open, TOUCH the metal frame of the open computer case.
This action will relieve your body of Static.

Should you walk away in the middle of working on your computer, upon your return TOUCH the metal frame again ]

3) Unplug all cables from the computer. If you are not VERY familiar, with where these cables plug into on the computer, it would behoove you to make notes, and a drawing if you wish.

Lay a towel or similar object on your work table. Helps to prevent scratching the table, and your computer.

Open the computer case. You will be removing a Side Panel. Facing the computer it is the Right side panel that you will remove.

Facing the back of the computer, there are two Thumbscrews you need to loosen. One towards the top, one towards the bottom.

Turn these Thumbscrews to the Left to loosen. They should not come all the way out, and will hang there.

You will see a raised 'Hump' (Protrusion), in the Side Panel. This is an area in which you place your fingers, to remove the Side Panel.

The rear of the Side Panel swings away from the computer, in order to remove it.
(Like a door)

[ Barring that my instructions may not be very clear, you can download the User Guide, with instructions, and photos for this,

Left-click on -
8511050 - Gateway Computer User Guide.

This is a PDF file.
It may take a few seconds before you see the first page, and additional time to fully download.
Suggest you let the file fully download before looking through it.

Opening the computer case starts on Page 51 ]

Once the Side Panel is removed, lay the computer on it's side on the towel, opening facing up.
Makes it a lot easier to access the Ram Memory modules.

Removing and installing ram memory modules starts on Page 55.

To me the information, and illustrations are unclear.
I'm going to detail my own information.

When you open your computer there will be many cables (Wires), which makes it tough to see the Ram Memory modules, and the ram memory slots they reside in.

In order to better clarify where the ram memory slots are located on the motherboard, I am going to give a link to Gateway Support, and an actual photo of the motherboard in your computer.

(No hardware components are installed on the motherboard. Bare motherboard)

At the top left of the motherboard are two Black ram memory slots, and two Blue ram memory slots.
To view the ram memory slots in a closer view, click on this link,

At each end of the ram memory slots is a white Lock.
The Lock is gently pulled out at the top.
The best method is to pull out on both Locks at the end of a ram memory slot, simultaneously.

This action raises the Ram Memory module up out of the slot.
Only remove one Ram Memory module at a time.

The Gateway GT5220 desktop computer uses DDR2 Sdram, ram memory modules.

(At 533MegaHertz

Mega = approximately 1 Million
Hertz stands for Cycles per Second.
The above ram memory, can operate at a frequency rate, Up To 533 Million Cycles per Second.

Another term used for DDR2 Sdram that operates at a frequency rate of 533MHz, is PC2-4200)

Below is a link for an up close photo of DDR Sdram.
Link given for clarity of the gold plated contact pins.

(DDR Sdram has 184 contact pins. 92 on each side.
DDR2 Sdram has 240 contact pins. 120 on each side)

(You can left-click on the photo to enlarge it)

Refrain from touching the gold plated contact pins.
You can hold the ram memory module anywhere else you wish. (Body)
The body of the ram memory module is coated with a see-through protective plastic coating.

Using the pencil eraser, start at the top of each contact pin, and stroke down. (The contact pins are on the bottom of the ram memory module)

If you use a pencil eraser that is on the end of a pencil, refrain from letting the metal under the eraser, touch the contact pins.

Once you are satisfied the contact pins are clean, use air pressure to remove the eraser dust.
You can use a can of compressed air for computers, or air pressure from your mouth may be sufficient.

Reinstall that ram memory module, go to the next one.

Viewing the ram memory module, you will note the cutout, or Locating Notch on the bottom.
At a cursory glance, the Locating Notch may look to be centered.
It is Not.

The ram memory module Locating Notch, lines up with a Locating Lug, in the bottom of the ram memory slot.

Align it in the correct position before installing.
The white Locks have a small slot.
The bottom corners of the ram module sit in these slots.

Locks eased all the way out to the side, the ram memory module is lined up with these slots, so taht the corners rest in the slots.

(And the Locating Notch is lined up with the Locating Lug)
As you press the ram memory module down evenly, the Locks come up.

Each Lock has a 'Bump', or protrusion.
This protrusion lines up with a Notch, at each end of the ram memory module.

When the ram memory module is full seated, and the Locks go into the Notches, you should hear two clicks.

The protrusion of the Lock may not fit very well into the Notch, so don't look for a precise fit.

Let's start here, and see where this diagnoses takes us.

[Would also like to add, that the inside of the computer, AND the inside of the Power Supply, should be cleaned on a regular basis as needed.

Computer unplugged from power, computer case open, use a can of compressed air for computers.
(Don't forget about the Anti-Static Precautions)

Use Q-tips on the thick 'Gunk'. You are only using them to break the 'crust'.
Then the can of air will remove the gunk.

Attach the plastic straw to the nozzle of the can of air.
Start at the top Left inside corner of the computer, shoot air across to the top right corner.

Use a spray method like a painter using a spray paint gun.
When you start press the trigger in all the way, as you approach the end of the row you are making, let go of the trigger.

Drop down a space. I drop down 1 inch.
Shoot air across in another row.
Keep going down in rows until you reach the bottom.

As you make your rows going down, you will approach the Processor fan.
Pay special attention to the Fan's blades, center hub of the fan, and the surrounding cage of the fan. (Shroud)

Use Q-tips to dislodge the thick gunk.
Use care when shooting air at the Processor fan.
You Do Not want to spin the fan faster than it was designed for.

Spinning the fan too fast, may lead to premature failure of the fan's bearings.
Use Short Bursts.
Squeeze the trigger in all the way, then let go]

Gateway wont startup. One beep followed by two short

Not sure where you got your information on the error codes but it is partly correct, it is video related, but it isn't the video card but rather the memory location in the ram that is used by the video card. You could try to remove the ram memory clean and re-seat it on the mother board and see if that fixes it, or if your motherboard has two or more ram memory modules, remove the memory and switch which sockets you replace them in (make sure you keep track of the original position of the modules because on some rare motherboards you have to use the memory in a picky order) after mixing up the memory modules check for a boot again, if this corrects the booting then one of the memory modules is defective and may need replacing. Note when you take your memory into a computer shop be sure to use a static bag and proper static precautions.

I would suspect the power supply or a power connection. The only other issue might be a motherboard, which is a bit more involved. Try another power supply if you have one around.
