Tell me if there is something i need to know like: what were the things that you've doing with your computer before the problem happened?? are there any recent hardware/software changes?? tell also your OS- is it XP or Vista...

first, let's try to check if the problem is with the monitor or not,okey? try unplugging the monitor blue connector at the back of the tower.and make sure that your monitor is turned-on.If you can see a colored bars monitor is okey.if not, try a known good monitor...if it woks the problem is with the old monitor.(resolved)

2 (if not)
Now, complelely turn off your computer and try reseating all the cables, and your hardware components such as memory,video card,IDE cable and so on. but before doing so, unplug the power cable and then push the power button to drain the power.after reseating everything, plug back the power cable and turn on computer.try listening to the tower,tell me if you can hear some beeps also.

if no video issue is still there, try putting a known good video card if you have any.if a known good video card works then the problem is with the old one..

if the problem is still there after everything that you've done try calling the manufacturer. this is lead to a motherboard problem but try to call them first.

Hp pavilion 760n when turned on it makes clicking sound for a while and stops the monitor screen is blank with only a curser flashing in the top left corner.

The clicking is coming from the hard disk - it has died - so the BIOS is signalling that the OS is missing - cursor flashing in the top left corner.
Replace the hard disk and reinstall Windows.

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.

Troubleshooting Power Supply Issues HP Pavilion A520n,

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."

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,

{ 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.

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.

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.

The power supply light is flashing and my computer won't start up. No fan, nothing. I disconnected the power to the mother board and the light burned solid when plugged in. I have switched the watts...

Bad Power Supply.
Weak voltage power rail, or rails.
{There are three voltage power rails.
1) The 3.3 Volt power rail
2) The 5 Volt power rail
3) The 12 Volt power rail}

The flashing Green LED light is one direct indication of this for HP computers.
Usually there is at least enough power to light LED lights, and spin fans, but your Power Supply doesn't even have that much power.

1) All of the LED lights on at once use less than 1 Watt of power
2) EACH fan uses 2 to 3 Watts of power
3) A typical Processor can use 51 to 125 Watts of power.
Depends on what Processor it is.

The HP Pavilion A847C desktop computer has an ATX power supply, with a maximum rated wattage of 250 Watts.

The ATX form factor for a Power Supply refers to it's case size, for one.
5-1/2 inches Long, 3-1/2 inches Tall, and 6 inches Wide
The common type of Power Supply used in over 80 percent of PC computers out there, and readily available all over.

HP Support > Pavilion a847c desktop computer > Main support page,

Click on Product information in the list
Now click on Product specifications

Finally click on > Motherboard Specifications, PTGD1-LA (Goldfish )

Scroll the page down to view the motherboard illustration and photo.

The replacement Power Supply has to have,

A) A 24-pin ATX main power cable.
In the motherboard photo, view the Ram Memory slots. The long Blue, and Black slots.

To the right of the bottom corner of the Black ram slot (Slot 4) is a whitish connector.
Two columns of 12 socket holes.
This is where the 24-pin ATX main power cable plugs into.
(ATX Power Connector in the motherboard illustration)

Typical 24-pin ATX main power cable,

NOTE the Lock Clip on the side of the connector.

B) 4-pin ATX +12 Volt power cable.
At the bottom Left corner of the Processor socket is a whitish square connector.
4 socket holes.
This is where the 4-pin ATX +12 Volt power cable plugs into.
(ATX12V in the motherboard illustration)

Typical 4-pin ATX +12 Volt power cable,

NOTE the Lock Clip on the side of the connector.

{The top of the Lock Clip is squeezed in to release it, and is held while the power cable is removed.
Same for the 24-pin ATX main power cable's connector}

C) SATA power cable.
Used for the SATA harddrive

The SATA power cable has 15 pins, and is the longer connector.
The SATA data cable has 7 pins, and is the shorter connector.

IF, the SATA harddrive has provisions for plugging in a SATA power cable, AND a 4-pin standard Peripheral power cable, ONLY USE the SATA power cable.
Otherwise you will burn up the SATA harddrive.

The SATA power cable plugs into the SATA harddrive.
One end of the SATA data cable plugs into the motherboard, and the other end plugs into the SATA harddrive.

Below the ram slots in the bottom Right corner are the SATA headers on the motherboard, that the SATA harddrive plugs into.
The Blue, Orange, Black and White connectors.

Of course the SATA harddrive only plugs into one of them.
Looking at the motherboard illustration you will see they are numbered.
SATA 1, SATA 2, SATA 3, and SATA 4.

IT DOESN'T MATTER which one you plug your harddrive into. (Or any SATA device)
That's the beauty of SATA.
BIOS will find the harddrive.
But for you, it will be easier to keep track of where the SATA harddrive is plugged in, if you just use SATA 1.

Typical SATA power cable,

D) 4-pin standard Peripheral power cable.
Commonly referred to as Molex. (Misnomer)

Used for optical drives, Fans, and other associated hardware.

Typical 4-pin standard Peripheral power cable,

E) 4-pin Small Peripheral power cable.
Used to be commonly used for a Floppy Drive.
For your computer it provides power to the Memory Card Reader.

Typical 4-pin Small Peripheral power cable,

Watch disconnecting, and connecting this connector. You can bend the pins very easily.
WATCH your fingers as the pins are QUITE SHARP!

All of the power cables listed above are standard for today's Power Supply's.

About the Wattage.
A computer ONLY uses the power it needs, and NO more.

If you put a 10,000 Watt power supply in, and the computer only needed 100 watts for what it is doing, it will ONLY use 100 watts.
To wit, if you install a Power Supply with more Wattage than 250 Watts, it will NOT hurt your computer.

If you need guidance in replacing your Power Supply, or recommendations for 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.

I need a new motherboard for my computer. currently it has a ASUS PTGD-LA motherboard. does it matter what kind i replace it with?? I have an hp pavilion a1020n desktop

Information about the stock motherboard is here if you want to compare it to possible replacements. It doesn't matter what board you get as long as it fits (micro-ATX style) and can support the drives you have (enough IDE and SATA connectors). Also, if you want to keep your current memory and processor, you'll need to find a replacement that supports them. Finally you need to make sure that you stay within the ratings of the system power supply, unless you plan to upgrade it.

Hope this helps. Thanks for using Fixya!

Dell dimension 2400 blinking amber light

1. Remove All External Devices
2. Check the Computer's Power LED
3. If the power LED has not changed unplug the Power Cable From the Computer Disconnect All Hard Drive Power and Data Cables and power on the computer. If still no go.
4. Remove All PCI, PCI-E, and AGP Expansion Cards .
5. Remove All Memory From the Computer
6. Reseat the ATX and 12-Volt Connections . The ATX connector will be a 4 pin square connector connecting to the motherboard from the power supply and the 12-Volt Connection would be the biggest connector with a lot of colored wires.
7. If still no go.
8. Disconnect the Power Connection to the Chassis Fan
9. If the light still flashes then it could be a power supply or motherboard failure. Try a good know power supply first and if that does not fix the problem it is the motherboard. Also check the back of the tower for 4 lights lables ABCD or 1234.
Rate if useful.

Power turns on then immediately off

The case shouldn't have anything to do with power getting to the motherboard. Though there should be a switch on the power supply to increase or decrease the voltage move the switch to the other position and see if the machine stays on.
