How to take apart a tower computer

  1. Unplug everything. Unplug all of the wires, computer cables and power plugs from the outside of the tower. After this, it's a good idea to pick up the tower and put it on a clean flat workspace, on its side.Open the case. Discharge any static electricity. If you are worried you may have a lot of static electricity, you can use an ESD strap to discharge it. Remove the sides of the tower by unscrewing the screws in the back of the case that hold them on. This is usually two screws on either side, but may be more. On the side where the computer parts are removed, the side may be screwed in with thumbscrews. Lay the computer down so that all of the components are exposed.Remove the cards. The cards usually consist of, the sound card, video card, network card and maybe a few others. Some of these devices are now integrated on the motherboard, so you may have few or no cards at all. You can remove the cards by unscrewing them from the back of the computer. They usually only have one Phillips screw holding them in. Remove the card by pulling it slowly and carefully; you will have to apply some force though.Take out the drives. The drives are in bays in the front of the tower and are screwed into the framework of the tower or in removable bays. You will need to unscrew several screws from this side of the tower and you will need to flip the computer over and unscrew the drives from the other side as well. Unplug all of the power cables and computer connections from the back of the drives. Pull the hard drives out of the back work area. Floppy and optical drives can now be pushed out the front. Some computer cases, such as certain Dells, have a system for the optical drives to come right out by pushing in releases on the sides of the drive and no unscrewing is required.Disconnect the brains of the computer. Remove the memory by unlocking the white end clips and pulling up on the memory carefully and unsnapping it from the connection. Remove the CPU fan by unsnapping it from its connection to the motherboard. Unlock the CPU holder by unlatching the small metal clip. Lift up and remove the CPU.Remove the power supply. Never open the inside of the power supply, as it may cause severe injury. Simply unplug the power supply from the motherboard. This is usually connected by a long white rectangle and requires a clip to be pinched to let it loose. Make sure the power supply is not connected to anything else inside. All that's left is to unscrew four screws on the back of the case that hold the power supply in place. Lift out the power supply.Detach the motherboard. The motherboard should be screwed in with between 6 and 9 screws, simply unscrew them and lift the motherboard out at a good angle so that it fits out the side of the computer. The motherboard may have to be pulled out of the back of the case with some pressure, where the connections for the computer cables are. You should now have an empty tower.

my tower will not turn on


It sounds as if your power supply is having issues, I would recommend replacing it.  If your good with computers, you can test the power supply: 1. Open the computer tower. 2. Find the main plug which runs from the power supply to the motherboard. 3. There should be 16 wires. 4. Find the green wire, short it to the black wire with a paper clip. 5. If the computer seems to turn on, its your motherboard having issues and you will probably need a new computer.  If it does not turn on, your power supply has failed, and you need to replace it.
I hope this helps!

Card Readers have disappeared


Don't believe the manufacturer when they say that the only choice is to reinstall - Your question of "what if they disappear again?" is valid, because it could very well happen.

Go into the Device Manager. Make sure that you can see hidden devices, and try to "refresh" the system. There should be a small button in the top pane to do this with. If you get no results, try going down to "Disk Drives". This is where the card readers SHOULD be showing up. If you don't see anything here, then you most likely have a hardware issue. Try once more to refresh for good measure, and to see if your computer can find them.

If you are comfortable with the inside of the machine, open up the side panel, with the power cable unplugged and the switch on the power supply flipped to the "O" side. Carefully follow the cables from the front panel where your card slots are to where they plug into the motherboard. Ensure they are properly plugged in.

If everything looks alright, you may have an issue with the hardware, either the slot device itself or the motherboard. Call up the manufacturer again, and see about getting your computer repaired.
