Asus power supply

Power supply failures in a HP computer can cause your computer to fail to turn on, to operate erratically or cause certain system components not function.

However, the power supply is one of the easiest parts of a computer to replace.
You don't need any special skills to do this.

If you're nervous about opening up your computer case and potentially damaging a computer component, don't be.

All you are really doing is plugging in power supply cables after securing the power supply.
The process should take 10 minutes maximum.

Shut down your HP computer.
Disconnect the power cable from the power supply on the back of your computer.

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.

Some of the below steps recommend removing physical parts within the computer.
While in the computer it is highly recommend that you be aware of ESD and its potential hazards.


Unscrew the side panel from the back of the case and slide it off.
Newer HP computers may have a case door you can open for access or have access buttons to press.


Look at the back of your HP computer case for a set of four screws near the top of the case. Remove these screws and set them aside.
Carefully slide your power supply out of the mounting brackets and set it on a clean working surface.
Do not disconnect any of the power connectors yet.

Slide your replacement HP power supply into the case and use the mounting screws to attach it to the chassis.


Use your old HP power supply as a guide to connect your new power supply to all the computer components.

Switch the power cables from each device from the old supply to the new supply so you don't miss connecting any cables.

Check that all the components have power cables inserted and the old HP power supply is completely disconnected from the system.

Close the HP computer case and plug the power cable into the new HP power supply.

Here are some web sites that will help you install your power supply correctly. Power supplies provide power to the motherboard and other components of a computer and need to be hooked up correctly to the components in order to give power.

I would suggest you see if the computer is dirty inside. This includes it's Power Supply.

The hardware components inside that desktop computer are cooled by air, are cooled by the Cooling Components.

Air is drawn into the computer case into the Top, or Side, (Depending on which way the computer is sitting), by a computer case fan, (Chassis Fan), and is exhausted out of the rear of the case by the Power Supply's fan..

As the drawn air makes it's way through the computer case, it is also drawn in by the Processor Fan.
The Processor Fan pushes air through a Heatsink, which sits on top of the Processor's case.

The Processor Fan, and Heatsink strive to keep the Processor within a certain operating temperature.
(Thermal Range)

If the temperature is exceeded, the Processor turns off. (BIOS turns it off)
This is a Fail safe feature built-in to keep the Processor from burning up.

Typical construction of a Heatsink is plate of metal with tall, thin fins protruding from it.
The plate of metal absorbs heat from whatever object it is placed against, (In this case a Processor), and the tall, thin fins absorb heat from the plate of metal.

The tall, thin fins then radiate the heat away. The Processor Fan helps to carry heat away from the fins, by the produced air flow from the fan.

If the Chassis Fan, (Computer case fan), Processor Fan, and Heatsink are clogged with 'Gunk', the cooling capacity of these cooling components drops tremendously.
('Gunk' = Dirt, dust, hair, etc.)

I would start with cleaning out the inside of the computer, and the inside of the Power Supply.
Computer on a table, computer UNPLUGGED from power, computer case open.
Observe Anti-Static Precautions, and use a can of compressed air for computers to clean.

When you set the can of compressed air up, you will insert the plastic 'straw' into the nozzle, and break the lock tab used for shipping, off of the top of the can's nozzle.

Start at the inside top of the computer case, and start from one side. Left or Right is totally up to you.
Squeeze the trigger in all the way, go across the inside of the computer at the top.
As you arrive to the other side, let go of the trigger.
You are using the can of compressed air like a spray painter would.

Now drop down a space, and go across again. Spacing is up to you. You will see how much the air spray covers, and can judge accordingly.
Keep dropping down in rows until you arrive at the Processor Fan, and Heatsink.

The Processor Fan is only designed to spin so fast. Spinning it faster than it was designed for, can lead to premature failure of the fan's bearings.
For this reason i advise using Short Bursts.

Squeeze the trigger in all the way, but let go quickly.
(Remember what I stated about observing Anti-Static Precautions. If you are not aware of what Anti-Static Precautions are, please state in a Comment)
You may find that the buildup of 'Gunk' requires the use of Q-tips to help.

The Q-tips are just used to 'break the surface' of the Gunk. Not really used to remove it. Once the 'crust' of the gunk has been disturbed, the air can remove it more easily.

Use the straw to clean out in-between the fins of the Heatsink.
Air needs to flow freely in-between the fins.

Keep dropping down in rows now, until you reach the bottom of the computer case.
Hold the computer case with one hand, and the compressed air with the other hand.
Tilt the top of the case slightly towards you.
This helps to allow the air flow from the can of compressed air, to move the last of the Gunk out of the computer case.

Now go to the Power Supply's case from the inside of the computer.
Insert the tip of the straw part way into a ventilation hole, of the Power Supply's case.
HOLD on to the can of air with one hand, and the straw with the other hand.
The straw might shoot off of the nozzle otherwise, and it's NO fun trying to dig the straw out of the Power Supply's case.

Move from ventilation hole to ventilation hole, and spray air. You are just trying to clean the best you can. It won't be sparkling clean when you are done, but a LOT better than when you started.
Now go to the outside of the computer, and to the Power Supply fan.
Clean the fan blades, center hub, and surrounding cage. (Shroud)
Q-tips comes in handy here also.

You will find that after using the can of air for a while, that the air pressure drops.
This is because the air is coming out so fast, that the nozzle freezes.
When this happens set the can of air down for a while, and let the can warm up.

You will also find that if you tilt the can, some of the propellant shoots out. Try to refrain from tilting the can, but if you are doing a good job, this is inevitable.
Allow the computer to sit for at least 10 minutes after you are done cleaning, then close the case, and plug it in.

(The propellant is Flammable with most cans of compressed air. DO NOT use around sparks, or open flames. You are letting the computer sit for 10 minutes, so that any propellant that may have come out, will dissipate)

I would also advise removing all Ram Memory modules, ('Sticks'), and cleaning the gold plated contact pins on the bottom.
Use a pencil eraser to clean. Clean each contact pin on both sides. Doesn't take long.
You don't have to rub the eraser on the contact pin very hard.

In fact you may not even see that you have accomplished anything. I assure you that you have.
Corrosion develops on those gold plated contact pins.
Doesn't take very much to create a bad contact surface.

Use air to remove the eraser dust. If you have air leftover from the can of air, (Doubtful), use it.
Otherwise air pressure from your mouth will be sufficient.
Replace the Ram Memory modules correctly, amnd make sure they are seated well.
If you need guidance, please post in a Comment.

You may find that the Thermal Paste has dried up in-between the top of the Processor's case, and the bottom of the Heatsink.
Perform the above procedures, and if this is to no avail, post, and I will outline how to clean, and properly apply fresh, new Thermal Paste. (Thermal Paste is also known as Thermal Grease)

1) Computer Cover = How to remove the computer case cover

2) Before You Begin/Safety Instructions = Advice on Anti-Static Precautions also.
(CAUTION at the bottom)

Buy a can, or two, of compressed air and blow out all vents, fan blades, anywhere that you see dust accumulation inside of the PC. When cleaning the fan blades, it's best that you just use an old toothbrush to remove the dust manually, because it tends to cling firmly on those particular parts.

Also, be sure to focus air around the vents of the power supply unit (PSU, power box). This is the box that powers your PC. Hopefully, this small task will be just the thing to breathe new air into your PC. :)


Hope this helps. :)

ha ha unlucky m8 these are the tools you will need and the steps you will have to take to open ur ps3 :)

Tools Needed

• 1 Small Socket Wrench
• ¼ inch Socket
• (1) T-10 Star Tip Point – that fits ¼ inch Socket
• Philips Screw Driver

How to Do It:

1. Remove the Warranty Sticker
2. Behind the Warranty Sticker you’ll find a star tip screw. So set up your socket wrench with the star tip point and unscrew the screw.
3. Remove the Screw and Remove the Plastic PS3 Top Plate
4. Now you’re looking at the console you’ll have to remove (7) Screws, Notice (6) of them will be long and 1 will be shorter than the others
5. Remove all the screws, once that’s finished start at the back of the console and pop the unit open with your hands.
6. Now you should have the console open and you’ll seen the disc drive and power supply

The motherboard will support any PCI Express x16 or PCI Express 2.0 x16 video cards. Your main concern should be with the power supply since it is either a 300w or 250w.

Here is a pretty good choice for your price range:

A little money for system memory would be good if you have less than 1 Gig.
You can test it here:

If you are saving money by not buying a motherboard and want to spend it (which is what I would do), I would put the money into a the video card and power supply.
Like this:

I do not know the dimensions of the Aspire Case, so one thing to keep in mind is the dimensions of the card and the power supply. Make sure they will fit before buying.

If you start replacing motherboards and such, you might as well just go with a whole new system. A new motherboard, new CPU, new memory, new graphics, new power supply, fast hard drives, new case.

Check the power supply if its giving the correct voltage on the mother board.

I know you're going to say it have power, but sometime it happens, It happend to me once, there was power and everything check everything and its working fine but when i put it back together nothing's seem to be working. I swap the power supply and bingo.

try using a bare system only means motherboard, psu, processor, ram then connect a speaker, does it make any sound ?

For getting display, you must have four components,
1. CPU (alongwith cooling fan)
2. Motherboard
3. RAM & of course
4. Power Supply (SMPS)
They must be connected properly and after attaching power supply unit you must ensure that a 24pin connector as well as a separate 4pin connector are connected to the Motherboard.
If the display doesn't come, the trouble may be with any of the four devices connected together. for advanced trouble shooting, please elaborate exactly when and how the problem has been generated. If the problem arised at the stage of initial assembly of the components, please check the components individually, if possible, replacing with another prouct of the same type.
If the problem arised on a running machine, please remove the RAMs from the slot, wipe the connectors of the RAM with a softe clean cloth and re-attach. If possible, you may wish to clean the RAM-slots on the board with a vacuum cleaner. In most cases, cleaning the RAMs do the needful.
Please try & reply.

If you haven?t done so already pull the battery and unplug the AC power converter. Chances are good that the damage is already done; however, there is a chance that after a good cleaning and all liquid is completely removed it may still work. The problems that have to be dealt with is that the soda ingredients are great electrical conductors plus the sugar will gum up the keyboard and other moveable components. What needs to be done is the keyboard needs to be removed, cleaned out and thoroughly dried out. If you can get the soda out before it dries then you?re in good shape. If not the keys will be sticky and pretty much unusable. You can try blowing it out with compressed air, Q-tips, paper towels, ect. After removing and dealing with the keyboard the next step is to determine if any of the liquid has dripped down into the lower part of the laptop. If it has then you?ll have to go through the same process. You have to ensure all of the liquid is removed from all moving parts and electrical boards and components. Remember if you don?t get everything you?ll risk the real possibility of gummed up parts or electrical shorts. Lastly if the laptop despite your best efforts will still not work chances are good that the data on the hard drive can still be recovered. Let us know what happens and if we can help further.
