It may seem as though the computer is working fine, but I suggest you have a bad Power Supply.

Weak Voltage power rail.

Power Supply's are rated in Wattage.
The Gateway GM5088 Media Center desktop computer, uses a 300 Watt power supply.

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

2) EACH fan uses 2 to 3 Watts

3) A typical Processor can use 51 to 125 watts. Depends on what Processor it is.

The Gateway GM5088 comes with an AMD Athlon 64 4600+ processor. (2.4GHz)

Can use up to 110 Watts.

This is why lights light, you may see fans spin, and it may seem as though the Harddrive is operating.

Not enough power to turn the Processor on.
The Processor is the 'Brain'.

No 'Brain', the boot sector on the Harddrive won't be found.
The harddrive Spindle motor, is just sitting there spinning the Platter's inside the Harddrive.

[Information on Harddrive's ]

Suggestion is to either test the Power Supply voltages, or replace the Power Supply with a KNOWN to be good, compatible unit, for a test.

You can test with an inexpensive multimeter, or a power supply tester.

One example of a power supply tester,

Most of the time this 'ailment', can be attributed to the inside of the
computer is dirty, as well as the Power Supply.

There are two cooling hardware components for the Power Supply.
The external fan, and Heatsink's used inside the Power Supply.

[Typical construction of a Heatsink, is a square, flat plate of metal that has tall, thin fins protruding from it.

The flat metal plate, absorbs heat from whatever object it is placed next to.
The heat is then absorbed into the tall thin fins, whereby it is radiated away.

Air flowing in-between the tall fins from the fan, helps to dissipate the heat even further]

Once the fan blades, and fins of the Heatsink are coated with gunk, (Dust, dirt, etc), the cooling capacity drops tremendously.

Heat = Wasted Energy

The Power Supply tries to keep up with the call for power, eventually cannot, and hardware components inside the Power Supply fail.

The rest of the time, it can be attributed to a low quality power supply that was installed.

Sounds exactly like a failing power supply. Hopefully you bought an extended warranty when you purchased the computer. You should look into having the PSU replaced.

Gateway computer power light flashes before booting up.

Hmm. I wouldn't have thought it had anything to do with pressing the button. It sounds more like a failing power supply or lack of current for startup. Did you make sure you plugged the power into the video card power connector (if it has one)? I know it worked ok at first but a heavier load can cause older or under-rated power supplies to fail soon after. Just a thought.

The problem is not with your monitor cable. The first thing I would do is remove your ram sticks and clean the contact points with alcohol and a linen cloth (usually found near the fine china). Blow out the slots with canned air and reinsert, making sure they are fully seated and snug. Do the same for any PCI or PCIE cards in the machine. Try again. (Defective memory can cause this problem as the motherboard needs that component to post.) If that doesn't work, it may be one of several major things. The first to check is the power supply. A computer place can do this, but if you have one around or can get hold of a known good one, try that first.
If the memory and power supply are good, the problem is more than likely your motherboard. You can Google the Gateway DX4640-UB101A and "motherboard" to see which one is in your machine. Or see if Gateway can give you a hand.

You might want to make sure the harness is plugged into the right pins on the mother board.

Gateway laptop will not power on

Sounds like to me, that you do have power going to your computer(other wise your lights wouldnt be on), but that your hard drive is dead.

You can take it to a computer shop and have them replace your hard drive.
