Question about Gateway GX7022E (RBGX7022E) PC Desktop

1 Answer

Power Supply Put a NIVIDA 7950GT in the machine last night and discovered it only had a 130W power supply when it died after startup. The machine is advertised to have a 400W power supply. Had to go the the local store and shell out another $89 for a 400W power supply. Overall happy with the computer. Anyone else see the issue with the power supply ?

    No, since the computer was two years old I just purchased a new power supply. You are correct, I should of called Gateway and complained.

    Thanks for the response.

    Just curious. My computer is also a GX7022E and my power supply is 400W and is stock Model number ATX-400GW made by Bestac. Did you ask Gateway about this?

Trying not to be too snarky but that card is over 10 years old. Hope it was free because that's all it's worth, if that.

And as for your computer having 130w psu, well it must be even older. I know it must still work but depending on what you're trying to run (games?), everything else in there is too old as well, cpu and memory here (too slow, not enough) .

You should take that PSU back, get a refund and get a newer machine.

SOURCE: GT4022 Gateway FIC KTBC51G Motherboard died

How did you determine that the MB was dead? Do you know how to use a post card and do you have one? How old is your computer and is it worth it to replace the MB? It is usually fairly easy to find a replacement MB on Ebay. Although, today desktops are so inexpensive that you may want to try that route. If you do replace the MB make sure that your power supply is adequate. We build systems every day and we never use less than 450W. If you do decide to replace the MB email me if you run into any problems and I'll see if I can assist you.

Unplug the four-pin 12V ATX cable from the motherboard, and see if that makes it power up any better - it probably still won't work entirely, but see if it gets your cooling fans spinning. If so, you probably have a bad motherboard, with something shorting out the 12V power.

SOURCE: Gateway GT4022 has issues powering up and restarting

1.Yes the Power On switch is okay.
(PS. If you hold down the Power On button for 10 seconds on any computer, it will turn off)

2.The heatsink held down by springs on the Northbridge, and Southbridge chipsets, is an excellent idea. Works very well on Processors too.

My opinion.

1.This means even pressure is being distributed, and in a manner that a user can't cause harm to the chipsets.
Use screws, and you might have someone who puts too much force, while torquing them down.

2.Means to me that the user can remove the heatsink, clean the top of the chipset, and bottom of the heatsink, and apply new thermal paste.

Thermal paste does dry up over time.

[I'm sure you're aware, but please indulge me.
The top of a chipset, or processor case, and the bottom of a heatsink, is not perfectly smooth.

There are microscopic hills, and valleys, and pits.
These cannot be seen by the naked eye.

These voids cause an air pocket. Air is an insulator, not a conductor. You want a conductor to help transfer the heat from the chipset, to the heatsink.

Thermal paste fills these voids, and is an excellent conductor of heat. Helps transfer the heat.

If your Northbridge, and Southbridge chipset have thermal pads, I suggest taking them off, and flying them out the window!
(Look out below!!!!)

Thermal pads do not transfer heat very well]

As for your problem, it's the power supply.
Inside the power supply are Electrolytic Capacitors.

Some are used to filter the incoming AC electricity, Input Stage), and some are used to filter the outgoing DC electricity. (Output Stage)

Electrolytic Capacitors used in personal computers have a cylindrical aluminum case, with two terminals coming out of the bottom.

The aluminum case resembles an aluminum Coke can, with the bottom cut out.
There is a rubber round plug in the bottom.
The top of the 'can' is flat, and has an X or a lK, cut into it part way.

Inside the 'can' are three thin strips.
1) A Conducting strip of metal

2) A Non-conducting strip. Is made of metal with a non conducting oxide layer. (Insulating oxide layer)

3) A strip of paper soaked in Electrolytic Paste.

The Positive terminal is connected to the Conducting strip, and the Negative terminal is connected to the Insulating strip.
(Metal strip with insulating oxide layer)

Electrolytic Capacitors break down over time. The designer has taken this into effect, and puts in capacitors that are 50% better than required.

Problem is, that a large number of capacitors have a bad Electrolytic Paste formula. This formula was stolen from a large capacitor manufacturer.
Unknowingly the thief stole a bogus formula.

The Electrolytic Capacitor manufacturer caught wind of the approaching theft, and a known bogus formula was substituted for the real one.

The Electrolytic Paste of this bogus formula, develops gas after time. (Hydrogen gas)

This causes one of two things, or both.

A.The gas expands inside the capacitor, and breaches the seal of the capacitor.
(Pops the rubber plug loose at the bottom)

B. The X, or lK shape at the top of the capacitor breaks open. (The shape is etched into the flat top of the capacitor, about halfway)

Electrolytic Paste is slowly pushed out of the capacitor. Either through the break at the top, the rubber seal at the bottom, or both places.

Some paste loss will make the capacitor weak. (Loss of capacitance)
Too much paste loss will make the capacitor fail.

Electrolytic Paste also dries up.

When you have one, or more weak capacitors in a power supply, you have a weak voltage power rail.
When you have one, or more failed capacitors in a power supply, you lose a power voltage rail.

There are three main voltage power rails, in a personal computer power supply.
A) The 3.3 Volt rail
B) The 5 Volt rail
C) The 12 Volt rail

A capacitor builds a charge up slowly, then releases it all at once.
Compare this to a swimming pool that is filled up slowly with a garden hose, then knock a big hole in the side. The water rushes out all at once.

I believe you have a bad power supply. One, or more capacitors are failing. When you unplug, wait 15-20 seconds, then plug back in, you are causing the weak capacitors to get a surge of electricity.

I Do Not advise opening the power supply to take a look!
Electrolytic Capacitors hold a charge for weeks, sometimes months, after being disconnected from power!

(Sometimes up to a year for the big capacitors. Such as the one's used in the Input Stage, of the power supply)

If your fingers make a circuit by touching the two terminals of a capacitor, YOU will receive the charge!

If your fingers touch a circuit, in the circuit board of the power supply, where one, or more capacitors are in, and your fingers complete a circuit, YOU will receive the charge!

This can result in a bad to fatal shock.

An experienced tech, will use the proper method of discharging the capacitors, before working on the power supply. I will not detail it here.

(If someone tells you that you can use a metal screwdriver to do so, this = NO!
The tip of the screwdriver can melt, and turn into hot shrapnel, as the capacitor explodes!)

Seasoned tech's just use a spare power supply, for a test.

Approximately 70 or more percent of the computers that come to my shop have a failing, or failed power supply.

Most are due to the inside of the computer, and the power supply, is dirty.
The owner never took the time, or was afraid to clean the inside of their computer. (And power supply)

All they had to do was unplug the computer from power, open the computer case, touch the metal frame of the computer case to relieve their body of Static electricity, and use a can of compressed air for computers.
That's it!

The rest of the power supply failure, can be attributed to the computer manufacturer. They used cheap quality power supplies, that had cheap quality components inside. (Like Electrolytic Capacitors with the bogus formula, for one)

Saved the computer manufacturer money.

At the outset of this, you better check the Electrolytic Capacitors on your motherboard.

Gateway didn't use solid capacitors, when the FIC KTBC51G motherboards were made.
Gateway used Electrolytic Capacitors.

Visual signs of capacitor failure,

PowerEdge t110. powered on, led 134 light up a sec, the system fan starts & shuts off. then all leds 1234 light up and off. all turns off & after few seconds, the amber light goes on and no blinking.

Sounds like the power supply is dying. Startup is the highest power draw. If there is a CD or DVD drive, make sure there is no disk in the drive. The optical drive startup is a huge power draw when starting. You should also disconnect any eternal peripherals. You might want to try disconnecting the hard drives, as they also have a large draw. If it starts after that, your supply is probably dying. Looks like a 300 watt supply. Looks like these are about the age I'd epect a power supply to die. I'd get a supply rated about 500 watts, but make sure if fits. Dell often uses proprietary supplies that are odd sizes. I'd look for supply from pc power and cooling or look at the site for reviews of any 500 watt model that will fit.

You can test the power button. Remove the wires from the power on pins on the motherboard. Momentarily jump the two pins with a small screwdriver. If the computer starts the power button is bad. If it still doesn't start then something else is wrong. Did you test the memory? Also do all of the fans work, especially the CPU fan? It can't hurt to test with the other PSU. You know the HDD is good. Test one piece of hardware at a time and hopefully you will find the problem.

Computer will not turn on

Best way to check is to open your case. Near the power supply plug to the motherboard should be a little led light. If it is getting power to the board this light should be green. If it's unlit then most likely your power supply has gone bad. Hope this helps.

Startup problems

Have you considered it could be the battery has died. Have you tried external power? If the battery is OK then check the battery contacts to make sure they are clean. Has your power supply died and it won't power the laptop or charge the battery? It could be the motherboard but I'd put my money on it's power supply or battery. Without more details being supplied.
