Remember the power supply is usuall a pretty tight fit. Be very carefull of the RAM. You might want to take the ram out if you feel comfortable doing so, it will give you more room to work. You can also take the screw out of you drives and slide them out of the case to give you more room. It will come out, just don't force it. http://www.highpowersupply.com/product-ps-sia400M2.html

Good Luck friend!

Thease power supplys are usally installed verry tight make sure all 4 screws are out from the back and try to wedge a flathead screwdriver gently into the crease around the powersupply and nudge it out.

Replace power jack


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.
http://www.kitchentablecomputers.com/static.php - rules
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.

Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty http://pcsupport.about.com/od/toolsofthetrade/f/powersupplytest.htm Testing & replacing the PC's power supply http://www.youtube.com/watch?v=hbNxhvm0czs One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules 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 Remove the memory modules from their slots. Take the opportunity to clean the slots on the motherboards and the memory module connectors. Use compressed air to blow dust away and clean contacts with a soft cloth. Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components. Do not use solvent that may attract dust and never poke things like cotton buds in to slots. lightly rub an alcohol (Methylated Spirits) on a cloth not to hard let the alcohol do the work on the copper gold or silver tabs and r Allow the pins to dry. They will air dry in a matter of minutes. If reseating the memory did not resolve the issue try swapping the location of the memory. If you have only one stick of memory in the computer try moving it to another slot and then boot the computer. Check the memory module and memory slot contacts. They are either copper tin or gold. The colour will tell you which they are. Mixing tin and gold can result in corrosion that prevents proper contact. Look for any sign of physical damage to the memory module, memory slots or the motherboard. Reseat the memory modules. You should hear an audible click when they are in place. Do not use too much force to reseat the memory module in to the slot this can cause damage to the module, slot or motherboard. The hardware that you are trying to access is damaged or failing.


The device drivers for the hardware are faulty or incompatible. Could be a problem with the Hard Drive or the Hard drives PCB http://www.onepcbsolution.com/ http://www.youtube.com/watch?v=du0Qd_3wFWM There is a connection problem such as a bad cable for internal hard drives
Test all power and data leads that attach to your hard drive SATA
the leads from your MOTHERBOARD TO THE HARD DRIVE make sure they have a secure dust free connections and are not faulty although very rare for sata lead to fail Make sure all leads that are attached to your drives dvd\cd and floppy (If Applicable) have secure connections and are not faulty. or just replace them they could be faulty a computer needs power and data to travel through every working device and continue its cycle and have an end so any faulty leads will end up with a computer error

Why does my computer say no imput signal


If you have used a desktop computer or have a dual-monitor setup, you have likely seen the "No-input Signal" error message on your computer monitor. The error message may point to a number of culprits. Accordingly, the solutions run from simple to complex. Prior to attempting advanced troubleshooting methods, check the connection first. Power off the computer and the monitor. Remove the cable that connects the monitor with the computer, then reseat it. Try a different port, if possible, then reboot the computer.
Connect the monitor to another computer if possible to eliminate the monitor as the faulty hardware. Shut down the computer. WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules 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 Remove all cables and devices plugged into the computer. Make a note of the port into which your monitor is plugged. Remove the left side panel when facing the front of the case. Unscrew screws or manipulate latches to remove the side panel. This process varies according to the type of case you have. Please consult your manual if you are unsure of how to remove the side panel. Attach the antistatic wrist bracelet's clip to a metal object, then ******** the bracelet. Locate your video card. (This will be the card that contains the port with which your monitor interfaces.) Remove the slot cover screw that secures the card into the slot. Remove any power cables that connect the video card to the power supply. Pull the card out of the slot. Examine the gold pins to check for any damage. Reseat the card if it physically appears to be undamaged. You should hear a click once the card is secure in the slot. Screw in the slot cover screw. Attach the power cable from the power supply unit, if applicable. Leave the case open for now. Reconnect only the monitor, power cable and any devices required to boot the computer, then restart the computer. Shut down the computer again if you receive the "No-input Signal" error message again. Remove any cables and devices you plugged in to restart the machine. Remove the video card with a spare or replacement by following the instructions above. Connect necessary cables and devices to reboot the computer, then restart it. Shut down the computer and remove cables and devices if the display still won't work. Unplug the power supply's cables from all devices on the motherboard. Make a note of each plug-in so that you can correctly connect all devices with the new power supply. Remove the screws that mount the power supply. Fit the new power supply into the mounting area, and screw in all screws. Attach all required power cables to devices connected to the motherboard. Attach the cables and devices required to start the computer. Reboot. Hope this helps.

I need to change my power supply in my HP Pavilion a705w, and the screws are on the back, the 4 main to the supply, but I'm on the other side of the power supply and I can't get in there to change it. How...


There should be at least 4 more larger screws, maybe even "thumb screws", that will have to be removed as well. These screws hold the sides of the case on. Try removing those and sliding the sides back to open up the case

My HP Pavilion turned off the other day and now won't stay on. It starts going through the boot up and then turns off before it gets to MS Welcome screen.


It could be overheating. If you are comfortable with opening up the case do this. Unplug the computer and place the it where you can work around it. Remove the knurled screw from the back of the left side panel. It's the one with the grill holes. Using canned compressed air blow the dust off of the cpu fan, back case fan, and the grill holes. Also blow out the power supply vent holes inside and the fan on the back. Hold the fans blades from spinning to prevent ruining the bearings. It could be a bad memery stick. Remove any cards and the memory sticks. Reinstall one stick, hookup the keyboard and display cable and power on the computer. If still nothing swap the ram sticks.
