Hello!

I guess that the computer have a one year warranty, You can claim a warranty anytime you want. But if has no warranty at all then you can repair the PSU by your own, Open the PSU and find any busted parts or maybe the fuse blownout that is very cheap you can replace that by your own. If afraid to do so, then let the repairman do it for you.
If no hastle it is recommended to by new PSU for your system.

Hope this help, best regards, melnavz

After i turn on my gateway model GT5404, the three fans turn on for 3-5 seconds, then stop spinning and my system does not turn on


Yes. Exactly. You have found the problem.

http://support.gateway.com/s/pc/R/1009371/1009371nv.shtml

Uses an ATX form factor Power Supply. One that is common in a LOT of desktop computers. Readily available.

Gateway Support indicates there are three generic Power Supply makers, for the Power Supply in your computer,
Delta, HiPro, and Bestec. (Same one's for HP too)

Indicates the form factor is uATX/BTX.
Whatever, Gateway.

An ATX Power Supply's case dimensions are approximately -
6 Inches Wide, 5.5 Inches Long, and 3.5 Inches Tall.

Power cabling is also a designator when referring to ATX.
The new Power Supply's on the market, cover ATX power cabling, and more.

This is an example of an economical, yet reliable, Power Supply, that will work,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4465483&CatId=1079

Has all the power cables you will need, plus more. Tie the unused power cables up out of the way. (USE plastic ties)
Concerned it is a 500 Watt unit, and not a 300 Watt unit as came with your computer?

No need to be.
1) A computer ONLY uses the power it needs, and NO more.
If you are surfing the internet, and the computer only needs a 100 Watts, it will ONLY use 100 Watts.

Playing an intensive game, or using an intensive program?
Could use the whole 500 Watts.

2) Will it harm your computer? No.
You could use a 10,000 Watt Power Supply, and it won't harm your computer. (10,000 Watt is an exaggeration)
Why?
Because a computer will ONLY use the power it needs, and NO more.

The green light on the back is flashing, but when I push the power button nothing happens, any ideas what it could be?


The Green LED light flashing indicates a bad Power Supply. Weak voltage power rail.

http://h10025.www1.hp.com/ewfrf/wc/product?product=404643&lc=en&cc=us&dlc=en&submit.y=7&submit.x=7&lang=en&cc=us

Click on > Power Supply light is on or flashes

"If the LED is still flashing (it should not flash with all connectors removed), plug the power cable into a different power outlet that is known to be good. If the LED still flashes, the power supply should be replaced."


Cause?
The leading cause is the computer is dirty inside, to include the Power Supply
The next cause is that Electrolytic Capacitors have failed inside the Power Supply.

Solution is to replace the Power Supply.

The Power Supply used is the ATX form factor. The type of Power Supply used in over 80 percent of PC computers out there, and very readily available.

Size of the power supply case is approximately 6 inches Wide, 5-1/2 inches long (5.5), and 3-1/2 inches Tall. (3.5)

It is a 250, or 300 Watt generic unit, probably made by Bestec, Delta, or HiPro.

Scroll down to see the illustration and photo of the motherboard.

Power cables needed are;

A) 20-pin ATX main power cable,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain20

{ ATX power supply's today come with a 20 + 4-pin ATX main power cable.
The power cable can be used as a 20-pin, or a 24-pin.

Add the 4-pin connector to make it a 24-pin, or do not use it, and have a 20-pin }


B) Enough standard 4-pin Peripheral power cables for the IDE (PATA) harddive, {1}, and the optical drive/s.

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

Today's power supply's come with either at least 4, or 6 of these power cables.

C) One Floppy Drive power cable.
Won't be used for a Floppy Disk Drive on your computer. It's power for the Memory Card Reader.

http://www.playtool.com/pages/psuconnectors/connectors.html#floppy


All of the above power cables are typical when purchasing an ATX power supply today.
Need guidance in choosing a Power Supply, please state in a Comment.

Why is my hp pavilion 523w not working it just makes enough power to make a green light flash


The Green LED light you see flashing indicates you have a bad Power Supply.

Computer unplugged from power, computer on a table, computer case open, observe Anti-Static Precautions.
Clean the inside of the computer out with a can of compressed air for computers, (Or may take two, and a few Q-tips), and replace the Power Supply.

Compaq sr1350nx Well, just installed a new motherboard and replaced all the parts correctly as they were. Checked all connections fired it up and actually got a screen with a few numbers then a blinking...


It IS the Power Supply cjshearer11.

The green LED light flashing is a diagnostic light now. The diagnosis is a bad Power Supply with a Gree LED flashing.

Secondly, notice how the accessories are unplugged, and the Green LED light is solid Green?

1) ALL of the LED lights combined 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.

Compaq Presario SR1350NX?
Uses an Intel Pentium 4, Model 519 (LGA 775 processor socket)

3.06GigaHertz maximum frequency rate (3.06GHz 'speed')
533MegaHertz Front Side Bus. (533MHz FSB)
1MegaByte of L2 cache. (1MB L2 cache)
Can use up to 89 Watts,

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors#Prescott_.2890.C2.A0nm.29

You press the Power On button. Inside the plastic Power On button is a Power On switch.

(Typical ATX power on switch,

http://www.directron.com/atxswitch.html )

The Power On button presses against the Power On switch making a momentary contact.
(The Power On switch is a Momentary Contact Switch)

This closes a circuit temporarily that has 5 volts present. The 5 Volt Standby power.
(The 5 volts is always present when the Power Supply is plugged into power)

The 5 Volts is directed towards a circuit within the Power Supply.
The Soft Power On circuit. (PS_ON)

This in turn 'excites' the Power Supply, and turns the Power Supply on.
(No pun intended)

The first chip on the motherboard to receive power is the BIOS chip.
(Chip and Chipset are slang terms for I.C.
Integrated Circuit)

Burned into the BIOS chip is a small program. The BIOS program.
The BIOS program 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, and Windows Vista are two examples of an O/S)

Your Power Supply has a weak voltage power rail.
(There are three main power rails in the SMPS in your Presario computer's Power Supply.
{Switched-Mode Power Supply}
The 3.3 Volt power rail, the 5 volt power rail, and the 12 volt power rail)

Enough power to light LED lights, and maybe spin fans, (Or spin a few times, and stop), but Not enough power to turn the Processor on.
NO Processor operating, no finding the boot record of the Operating System, on the Harddrive.

Do you have a KNOWN to be good, compatible power supply in an unused desktop computer, to use for a test unit?
Someone you may know may have upgraded to a better computer, and have a working computer with a Power Supply that you could borrow.

Needs to be an ATX form factor Power Supply.
Form factor for a Power Supply refers to the size, and shape of the case, for one.
It also applies to the power cables coming out of the power supply.

The size and shape of the case is;
6 inches Wide, 5.5 inches Long, and 3-1/2 inches Tall.

Needs a,
A) 24-pin ATX main power cable,
B) 4-pin ATX +12 Volt power cable,
C) Enough standard 4-pin Peripheral power cables, for the optical drive/s (CD/DVD drive/s),
D) One SATA power cable

A) 24-pin ATX main power cable:

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

B) 4-pin ATX +12 Volt power cable: (Power for the Processor)

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

C) SATA power cable: (Power for the SATA Harddrive. 15-pin cable)

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

D) Standard 4-pin Peripheral power cable:

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

The ATX power supply inside that Presario, is probably rated at a maximum Wattage of 250 to 300 Watts.
Made by some generic Power Supply manufacturer.
Bestec, HiPro, or Delta.
Around 90 percent of the desktop PC's out there use an ATX Power Supply.
You can buy one with as much Wattage as you want, won't hurt the computer.
A computer ONLY uses the power it needs, and No more.

Nothing happens when I press power button


1) Make sure THE receptacle in the surge protector that the computer is plugged into, has power. Plug an electrical device such as a table lamp for example, into THAT receptacle. I have had a few surge protectors where just THAT receptacle was bad.

2) Receptacle checks out, I suggest you see if the problem is the Power On switch, or the Power Supply.
(The Power On switch is located in the plastic Power On button.
This is an example of a generic ATX power on switch,

http://www.directron.com/atxswitch.html

The procedure involves bypassing the Power On switch.
If the Power Supply comes on you have a bad Power On switch.
If the Power Supply does Not come on, you have a bad Power Supply.

The procedure does not involve the wires of the Power On switch, nor the switch itself.
The procedure involves using a jumper on the ATX main power cable's connector.
Jumping from the Soft Power On wire (Green wire) to ANY Ground wire.
(ANY Black wire is a Ground wire)

The Acer Aspire T180 uses a 24-pin ATX main power cable.
The 24-pin ATX main power cable plugs into the motherboard, in-between the Ram Memory slots, (Slot 4), and the outside edge of the motherboard.

This shows you a typical 24-pin ATX main power cable, it's connector, and the matching female connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

This is to show you the motherboard, (Not advertising for the website, nor the seller),

When you open your computer case, (Computer unplugged from power), you will see various cables, and hardware components, plugged into the motherboard.

Viewing the photo in the link above, look to the right of the Orange Ram Memory slot.
You will see the blue connector.

The opaque whitish connector to the right of it, and next to the outside edge of the motherboard, is where the 24-pin ATX main power cable plugs into.

Looking back at the link that shows the 24-pin ATX main power cable (Playtool link), look at the photo to the far right.
This is what you will see when you open your computer case.

View the Green wire.
Now view the Black wires.

The jumper wire you will fashion, will go down into the socket hole with the Green wire, and ANY Black wire.

One end of the jumper wire, will go down into the socket hole with the Green wire.
The other end of the jumper wire will go down into a socket hole with ANY Black wire.

The jumper wire will go down into the socket hole, Right next to the wire that is already in the socket hole.

(The Back of the connector is where the wires go in. The Front of the connector plugs into the motherboard.
The jumper wire goes into the Back of the connector, down into the socket holes, and right next to the existing wire that is already in the socket hole)

At the end of the power wires going down into the socket holes, is a metal terminal.
The metal terminal is pretty far down into the socket hole.
(Approximately 1/2 inch)
You need to ensure that the ends of the jumper wire Touch the metal terminals.

The jumper wire is fashioned from a paper clip.
The paper clip is first straightened out, then bent into a U-shape.
Black plastic electrical tape is wrapped around the bend of the U-shape.
This taped area is where you hold onto the jumper wire.

The voltage for the Green (Soft Power On) wire is 5 Volts DC.
Two D cell flashlight batteries produce 3 Volts DC.
Low, low voltage in case you are concerned of being shocked.

However, you may wish to wear a glove on the hand that holds the jumper wire.
There may be a small spark.

Suggest you lay the computer on it's side, computer case open, opening of the computer case up.
(Won't hurt the computer to operate laying on it's side)

Place the ends of the jumper wire into the socket holes.
The contact is no more than 2 seconds.

Power Supply comes on, you have a bad Power On switch.
Power Supply does not come on, you have a bad Power Supply.

The Power Supply is an ATX.
(ATX form factor.
The ATX form factor for a Power Supply is approximately 6 inches Wide, {Width},6 inches Long, {Length},and 3-1/2 inches Tall {Height)

It's a 250 Watt unit.

Green light in rear flashing won't part up


The green light flashing is a diagnostic LED light, telling you there is a power failure.
More specifically a bad Power Supply.
Weak voltage power rail.

The Power Supply used in a Compaq Presario SR1010Z desktop computer, is a 300 Watt unit, and is an ATX form factor.

[ATX form factor for a Power Supply, denotes the size of the Power Supply case, and the shape.
It is approximately 6 inches Long, 6 inches Wide, and 3-1/2 inches Tall.
The ATX form factor for a Power Supply is used in over 90 percent of the personal computers out there, and is as readily available as the air we breathe]

Usually, HP uses one of three generic Power Supply manufacturers.
1) Bestec
2) Delta
3) HiPro

All are low quality Power Supply manufacturers.

This is HP Support, and the main menu page for the Compaq Presario SR1010Z desktop computer,

http://h10025.www1.hp.com/ewfrf/wc/product?product=1146324&lc=en&cc=us&dlc=en&submit.y=7&submit.x=6&lang=en&cc=us

If you click on Manuals, then on Upgrading and Servicing Guide on the following page, there are instructions on how to open your computer case.

This is instructions on how to replace a Power Supply, from HP Support,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01356113&cc=us&lc=en&dlc=en&product=3548196

(It's for a Pavilion a6230n desktop computer, but after you open the computer case of your Compaq Presario SR1010Z, the instructions are the same)

What Power Supply would I recommend?
There are 100's to chose from.
This is but one example,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3276575&CatId=1078

Chosen because;

1) Maximum wattage is rated at 450 Watts.

A computer ONLY uses the power it needs, and NO more.
Wouldn't matter if you had a 10,000 Watt power supply, (No such thing. An exaggeration), if your computer only needs 100 Watts, it would only use 100 Watts.
(Surfing the internet typically uses 100 watts)

2) Has all the power cables you'll need, and more. Tie up the power cables you do not need. (Use plastic ties, Not wire, or bread wrapper ties)

3) 24 Amperes (24A) on the 12 volt power rail.

4) 135mm cooling fan.
The cooling fan on the Power Supply you have now is 80mm.

A larger fan turns slower. Produces as much air as a smaller fan, (Or more), but makes less noise.
Less wear on the fan's bearings also.

5) Is an ATX form factor Power Supply.

6) It's 80 percent efficient, compared to the 60 percent efficient Power Supply you have now.
(That is, if it was working)

When I push the startup button, the green light turns on the cooling fan start's just for an instent and shuts down. Even the Green light on the back of the computeris now turnes off. Any idea's to fix...


hshorty,

When you press the plastic Power On button, it in turn presses against a Power On switch.
The Power On switch is located inside the plastic Power On button.

This is an example of a generic ATX Power On switch,

http://www.directron.com/atxswitch.html

The switch completes a circuit.
(The Power On switch is a Momentary Contact Switch. Makes a brief contact, then opens back up)

The circuit the Power On switch completes, is the 5 Volt Standby circuit.
When a Power Supply is plugged into power, there is a constant 5 Volts (DC) present.
Closing this 5 Volt Standby circuit, momentarily 'excites' the Power Supply, and turns the Power Supply on.

Power goes to the Motherboard, and Peripherals, (Harddrive, optical drive/s, and so on)
The first chip to receive power is the BIOS chip.
(Chip and Chipset are slang terms for I.C. Integrated Circuit)

The BIOS program on the BIOS chip, looks to see what devices are installed, does a Ram Memory count, TURNS the Processor on, and hands the computer over to the O/S.
(O/S = Operating System. Windows XP is one example of an O/S)

Your Power Supply doesn't even have enough power to light those LED lights, much less turn the Processor on.

A) ALL the LED lights together, use less than 1 Watt of power.

B) EACH fan uses 2 to 3 Watts.

C) A typical Processor can use 51 to 125 Watts. Depends on what Processor it is. (Older Processors use less than 51 Watts)

If this problem is in reference to a Compaq Presario SR5130NX desktop computer, it comes with an Athlon 64 X2 - 3800+ Processor.

(Windsor Core. Also this Processor uses an AM2 processor socket)

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01048297&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=3436820

This Processor can use up to 89 Watts.

http://en.wikipedia.org/wiki/List_of_AMD_Athlon_64_microprocessors#.22Windsor.22_.28F2_.26_F3.2C_90_nm.29

Fans start to spin, and the LED power light is on for the Power Supply. When it's time to turn the Processor on, too much power is needed, and the Power Supply 'drops to it's knees'.

The Power Supply used is just a common ATX style of power supply. (Actually it is an ATX 12V 2.x)
Used in a LOT of personal computers out there, and is readily available.
It's a 300 Watt unit.

(The ATX form factor for this Power Supply, (Size and shape), is approximately 6 inches Long, 6 inches Wide, and 3-1/2 inches Tall)

Power cables from the Power Supply needed are;

A) 24-pin ATX main power cable (Main power cable to motherboard)

B) 4-pin ATX +12 Volt power cable, (Also known as P4)

C) At least one SATA power cable for the SATA harddrive, and additional SATA power cables, for each SATA optical drive.

(Your Presario may have come with SATA optical drive/s, or IDE {PATA} optical drive/s. Optical drive = CD/DVD drive)

D) If your Presario came with IDE, (Also known as PATA), optical drives, you'll need a standard 4-pin Peripheral power cable, for each drive.

E) The computer case fans, may each use a standard 4-pin Peripheral power cable. (The Processor fan attaches to the Motherboard)

F) The Memory Card Reader needs a Floppy Drive power cable. An auxiliary power cable.

An example of a compatible Power Supply,

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4465483&CatId=1079
