I have an old dell dimension 2400 and if it is anything to go by, I once did a repair and i did not re-seat the processor correctly. It just did P.O.S.T and stoopted everythig except the fans. You should check that ALL cables, adapters and components are inserted firmly. They could have been dislodged by a fall, or if you or anyone has been inside the pc, they may not have not put it together properly. Basically, I added a new meaning to push everything down more. (~.^)

I agree with the hard drive solution. I would check that first.

SOURCE: Fan is running, power button with blue light is off, cpu won't boot up

Your cpu might have died. As the computer is starting tap F8 and choose last known good configuration to see if you can get it started.

SOURCE: Gateway GT5220 PC desktop boot issue.

This is Nvidia's dreaded video chip cold solder joint problem. I have fixed many of these in my shop. Two choices, get it fixed or buy a new motherboard.

SOURCE: medion desktop does not boot up, screen blank.

Had same sounding problem with a Medion PC myself. I don't know the cause exactly but the fix I have is this:
Switch off PC, switch off PSU and unplug the power cable from the PC. Then press the power button on your PC. You may see lights and fans start up for just a brief second. This is because there was still charge in the PSU's capacitors which we needed to clear out.

You can now plug the power cable back in, switch on the PSU and turn your PC on.

(I realise this is too late for the original poster's uses but others may find it useful when searching for a problem!)

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,

http://support.gateway.com/s/PC/R/1009151/1009151ul.shtml

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)

http://support.gateway.com/s/MOTHERBD/Shared/4006136R/4006136Rnv.shtml

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,

http://support.gateway.com/s/MOTHERBD/Shared/4006136R/4006136Rmvr5.shtml

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
533MHz.

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)

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

(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]

I would actually lean a little more towards the power supply being the problem. You can either have someone locally test it for you, or you can buy a power supply tester to check it out.

Gateway MT6451 Does not turn on


Probably the mainboard or flaky power supply.

I'd start by replacing the power supply. Buy one you can use in a new machine, though... or "borrow" one from another machine.
