My name is getting around and I will soon be repairing computers and making some money. All power connectors should be removed, including the connection to the motherboard and any auxiliary fans.
Watch the little plastic tabs on ATX connectors you'ld rather not break them. AT power supplies have a two piece power connector that may be labeled P-8 and P Make note of the orientation.
The black wires should be in the middle, black to black. Remove the connection to the remote power switch at the front of the case. Orientation of the colored wires at this switch is critical. If you remove them, make sure you document well, and during re-assembly plug the computer into a fused surge protector before turning it on this could save your motherboard and components from melting if you've reconnected improperly.
If you're putting the same power supply back, it's better to remove the entire switch and leave the connectors entact. The remote switch on an ATX form factor attaches to the motherboard. Remove the four screws at the back of the case and gently slide the power supply out of the case.
While removing these screws, hold onto the power supply. You don't want it falling into the case. Removing the Motherboard Document and remove all wire attachments to the motherboard. Some of these have Pin 1 designations also. Most cases have a removable panel that the motherboard is attached to.
By removing a couple of screws the panel can be taken off and you can gain much better access to the motherboard. Again, a little investigation can save a lot of trouble. There is usually 2 or 3 screws holding down newer motherboards. Make sure you've got the right ones and remove them. Motherboards sit on plastic or brass standoffs that keep the traces and solder from touching the metal case and grounding out.
Once the screws are removed you can lift the motherboard out. In other cases, the motherboard has to be slid horizontally towards the bottom of the case to unclip the plastic standoffs and then lifted out. Place the motherboard in an antistatic bag. Assembling A PC: Same Way, Only Backwards When it comes time to put a computer back together, it's usually just a matter of reversing the order in which you took it apart. Again, you're going to visualize each step because there may be an easier way.
Is it easier to install the motherboard or the power supply first? If you install the power supply first, then you may be able to clip the power connectors on as you install the motherboard and tray. Tools When putting the computer back together or disassembling it for that matter , there are some basic tools that you'll find handy. Of course, you'll need your ESD protection equipment and a phillips screwdriver keep a flat-head screwdriver nearby, too.
A small flashlight and a magnifying glass may come in handy, as well as needle nose pliers. A useful device for any kind of computer work is a small srewdriver with a phillips head on one end and a flat-head on the other I have no idea what the proper name is for the tool. Once again, you're not in a race. A good carpenter measures twice, and cuts once. When working on computers you want to double-check everything you install or connect.
Before you start, make sure you have taken all your ESD precautions. As you continue, make a conscious effort to remain aware of these precautions. The Power Supply A fairly basic installation, just lineup the holes and screw it on. Don't plug it in yet. Remember, the cable going to the remote switch on the front of the case carries volts AC. If you took the wires off the switch, make sure you connect them just as they were before I hope you documented. A wrong connection here can burn up your PC.
After your power supply is installed, do not plug it in, you may not be able to tell if the switch is on or off and you don't want to turn the power supply on without a load. The Ram DIP memory modules are the hardest to install. Luckily, it's not done much anymore.
SIMMs are inserted at about a 45 degree angle then stoand up until they clip into place. If they don't clip in properly, maybe you have them in backwards. They'll usually have a key cut into one side. DIMMs are keyed on the edge connector side, they can only be inserted one way.
Once they are lined up, push them down until the locking tabs on the side come up. You may have to support the motherboard from underneath if it looks as though its going to flex too much. Pin 1 on the chip has to be lined up with pin 1 on the socket. This can be indicated on the socket with an arrow, a 1 silk-screened on the board, or a flattened corner. Usually the CPU will indicate pin 1 with a flattened corner and, or a dot on top, and, or an arrow on the bottom center of the chip.
Unclip and lift the handle, insert the chip, lower the handle and clip it in. These are rectangular in shape and have pins in two rows. They're keyed, and the cartridge should only fit in one way. Check any documentation that came with the motherboard or CPU, and refer to your notes. The Motherboard Most PC cases will allow you to remove the metal tray that the motherboard attaches to by removing 2 or more screws.
If you didn't do that during disassembly then you should familiarize yourself with it now. The plastic standoffs on the motherboard are to keep the solder-side of the board from touching the metal case and shorting out. Usually, it's better to install the RAM and CPU first to avoid the possibility of flexing the board and cracking solder connections or traces.
Orient the motherboard properly and either clip in, or slide in the standoffs until the mounting screw holes line up. Insert the screws that hold the board in place. The screws need to be snug, but do not twist them into the motherboard. You may be able to connect the power to the system board as you install the tray. A power supply with a baby-AT form factor will have two motherboard connectors P8 and P9.
These connectors are keyed but can be reversed. Make sure the black wires on the two connectors are beside each other.
Clip the keyed edge in at an angle, then straighten the connector up and slide it on. ATX power connectors slide in until the tab clicks. Once the motherboard and tray are secured in place, you can re-install the wires for the front of the case refer to your documentation.
