The Power Supply in the computer is bad. This is no big deal. You can replace it.

This is Gateway Support, and the main page for the Gateway 505GR Desktop PC,

http://support.gateway.com/s/PC/R/4054/4054nv.shtml

Left-click on Components.

Scroll down to the heading Power Supplies.

Left-click on - 102015 - 300 watt power supply.

It's just a common ATX style power supply, that is found in over 90 percent of personal computers. Readily available everywhere.

This is an example of an affordable replacement. It is not advertising for said website, nor power supply manufacturer.

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3255391&CatId=1078

What you need to look for in a replacement power supply for your computer.

1) Reliability
2) Correct power cables
3) Correct amount of power cables
4) Correct form factor. (Size of power supply case, and shape of case, in this instance)

2) & 3)
You need the following power cables, and these amounts.

A) (1) 24-pin ATX main power cable
[Main power cable to motherboard]

B) (2) 4-pin Peripheral power cables
[Power for the two optical drives]

C) (1) 4-pin ATX +12 Volt power cable
[Connects to the motherboard.
Power for the Pentium 4 processor]

D) (1) SATA power cable
[Power for the SATA harddrive]

The above power supply in the link has the correct power cables, and more than the correct amount.

Scrolling down the page you will come to the heading - Detailed Features
Here you will see,
A) 20 + 4 pin The two power cables are used together, to equal a 24-pin main power cable

B) 8-pin. Not needed in your case, unless you wish to install a graphics card that uses this power cable.
Just tie this cable up out of the way.

[You do have a PCI-Express x16 slot on the motherboard, which can be used for a PCI-Express graphics card]

C) P4 MB - Stands for Pentium 4 MotherBoard
This is a 4-pin ATX +12 Volt power cable

D) SATA
Comes with two SATA power cables. You only need one for your SATA harddrive. Tie the unused one up out of the way.

E) Peripheral
Comes with four Peripheral power cables. You only need two for your optical drives. Tie up the unused two.

F) FDD
For a Floppy Drive. Not needed. Tie up out of the way.

G) PCI-E
Also not needed unless someday you install a graphics card that needs this power cable.

Will add a link, to photos and descriptions of the various power cables listed above, that are needed, in additional comments.

Basic how to replace a computer power supply.

http://www.videojug.com/film/how-to-install-or-change-my-computers-power-supply

NOTE*
Your body carries Static electricity. Movements of your body in your clothes, walking across a carpeted floor, are but two ways static electricity is generated.

Static will fry out (Short Circuit) the components inside a computer.
The preferred method is to buy, and wear an ESD wrist strap as shown in the video.
However you can use another method.

Working on a table, computer unplugged from power, computer case open, simply Touch the metal frame of the open computer case.

Should you get up, and walk away when in the middle of working on your computer, remember to to touch the metal frame again upon your return.

Should you have ANY questions regarding replacing your power supply, please state so in a Comment.

Should you wish to test your power supply, also state so in a Comment.
[Will require a multimeter, or a power supply tester]

Have emachines monitor which is not coming on power button fast flicker


Which power button is flickering (your computer, or your monitor).
Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

Headlight wont work on passenger side of 2006 town and country


Try the working bulb on that side. Just because it is brand new doesn't mean it is good. If it still doesn't work push the wires on the back of the plug and see if it comes on if it does replace the head light plug. If not follow the wiring back and look for a break in the wire where it rubs against something

2000 acura tl 3.0 code p0304 , have moved coil around , moved s.plug , switched injector


Chris,
You need to check for both power and ground at the #3 fuel injector wiring harness connector. The power comes off of an ignition hot [has power when ignition is on] fuse. The ground is made by the PCM [engine computer]. Either borrow or buy [less than $15] a "Noid" light for your car. Noid lights are little test lights which fit into the injector wiring harness connector. With the engine running [or cranking], the Noid light should flicker on and off. If it does, your problem is mechanical [lack of compression] on #3. If the light does not flicker, use a test light to check to see if you have power at one of the two wires with the key in the ON position. No power, find and fix the open circuit in the wire. If you have power, than the issue is either the ground wire going into the PCM, or the driver diode [inside the PCM] is bad and you need a new PCM.

1997 bonneville sse. My power door locks work intermittantly. when they don't work they won't operate with door switch or remote. I also noticed that when they don't work, the interior car lights come on...


this is caused by a short in the wires.
now the best place to look for that short is at the fuse panel, or at the wires that go between the door and the car frame ( in that rubber acordic tube ).
so start at the fuse panel and use a volt meter or a 12 volt test light and trace and inspect the wires for splits,broken,burnt or unshielded exposed wires.
also check the wire harness that goes up and over the steering wheel shaft down by your feet area.
if you have checked all this and you are still having troubles - please feel free to write me back here and I will do my best to help you fix this problem.

Engine stalls #6 cylinder not fueling. Replaced fuel injector, plugs and wires. Checked compression. All good. Removed injector rail and placed #4 injector plug on #6 and injector started fueling. ...


sounds to me that you need a computer since the injector gets its signal from the computer. You can get a noid light from auto parts store to test the wire attached to the injector. The light should flicker when cranking the car. No flicker chances are you need ecm.

No spark


I assume you have already tested the (secondary ignition circuit) Locate your coil. Using a test light check for power at the small wires going to the coil, (primary circuit) Key on you should have a bright light, (battery power) I use a needle to insert into the back of the plug for this. Then check for power on the negative side of the primary coil wiring. (same plug) you should also have a bright light. Have someone crank the engine over and the light should flicker. If it doesn't flicker then you either have a broken timing chain so the distributer isn't spinning (Lift the cap and make sure the distributer is spinning.) or control problems. A spark igniter or wiring, or as a last resort ecm. If it does flicker then your coil is dead or coil wire is no good.

2002 hyundai santa fe 2.7 multi misfire number 2and 5 cylinders


OK IS THERE IS ACTUALLY A mis-FIRE THIS VEHICLE SHOULD BE SHAKING DURING IDLE AND ACCELERATION IF IT IS, here is what you do get a noid light this used to check injector pulse. This vehicle will set a misfire code if injector is not functioning efficiently or bad. A noid light is like a test light bulb can be bought at almost any auto store.SART UP VEHICLE AND DISCONNECT THE INJECTOR WIRE TO THE CYLINDER THAT'S mis-FIRING AND CONNECT noid LIKE TO ELECTRICAL PLUG. DO THIS ONE CYLINDER AT A TIME. The nod light should have a steady flickering light/consistent pattern of flickering. If there is Gap/irratic flickering or no flickering BINGO you have found your problem. NO FLICKERING= bad/broken injector wire if not broken BAD COMPUTER/ECU. IF THE FLICKERING IS CONSISTENT /GOOD = BAD INJECTOR..replace injector and solve the misfire problem. However is all the components tested are ALL GOOD. Then the only other SOURCE for a mis-fire is the camshaft sensor that provides reference for injector pulse and the crankshaft sensor provide reference for Spark pulse. JUST ON A LAST NOTE: make sure all oils are getting electrical power to them. Good Luck I know this is alot of info at once. Contact me if you need more help. Thanks fr using FIX YA
