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 Gateway.com.

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.
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.

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.
