Re: motherboard

All of the internal card readers I've seen either: -have built-in media converters which in turn plug into standard connections (USB, Firewire, ect.). -have their own PCI card with an appropriate connector for your card reader. That card plugs into your motherboard. Is it possible you card reader is missing something or perhaps was designed for some other motherboard?

3.5'' internal memory card reader/writer installation problem

Your reader/writer is set up for use on 2 USB ports (hence the 9 pin connector), one port for the reader and one for the externak USB port. This has nothing to do with the port version. The long and short of it is you need a card with a matching internal header. NEVER break off a pin! Some of these headers have reversed connectons so you probably broke of one of the data pins and runed that header's ability. Typically the readers like you have come with several cables, so that they can match the headers you have available. Older motherboards and add on USB cards did not use standardized header configurations aas you seem to have found out. Your best bet at this point is contact the manufacturer of the reader and find out what brand of add on USB cards they recommend and go with that. AND AGAIN NEVER REMOVE ANY PINS FROM A HEADER !!!

My card reader on my computer has stopped working!? ok i took my computer in to my computer teacher to get it fixed, well she put in a second hard drive in and said it should fine. well it does but...

Ah, My Bad, big_dude2010, perfectly understandable about the budget thing. The world is in an economic crisis right now.

As for reattaching the Card Reader cable, can't help you.

OH, I'm just PLAYIN'!

Before we go ANY further:

1) Computer off, and unplugged from power.

Unplug the power cable FROM the surge protector, and NOT plugged into the surge protector, and take it out of the back of the Power Supply.

With the power cable plugged into the surge protector, and unplugging it out of the Power Supply, you could create a voltage spike.

Result can burn out the Power Supply, and may go on to burn out the Processor, Motherboard, Ram Memory, and a graphics card. (IF used)

Many have stated, that they do this all the time. Eventually, they come back to state they fried out their power supply, and/or motherboard, and so on.

2) Computer unplugged from power, computer case open, TOUCH the metal frame of the computer case to relieve your body of Static electricity.

Static can fry out, (Short Circuit), the delicate hardware components inside your computer.
(For this reason also work on a table. If you have a carpet floor, refrain from swinging your feet back, and forth.
If you get up, walk away, then return, TOUCH the metal frame again)

If you already know the above, please disregard.

The Card Reader cable has a white sheath, and is approximately as thick as a No.2 pencil.

It should have 8 wires in it.
Orange, Yellow, Blue, Brown, Red, White, Green, and Black.

It will have a white rectangular connector on one end, that has 10 socket holes. 2 rows of 5 holes.
Only 8 socket holes are used.

The other end of the cable should have a Black connector. It also has 10 socket holes. 2 rows of 5 holes. This connector plugs into the circuit board of the Card Reader.

The White connector end plugs into the motherboard. It plugs into the Front USB 1 header on the motherboard.

(Connector on a motherboard is referred to as a Header)

Orienting the motherboard, so we are both looking at it in the same direction.
Processor to the top. Ram Memory slots to the right.
There are 3 white PCI slots down towards the bottom.

The white PCI slot that is closest to the edge of the motherboard, is PCI3. (PCI 3)

Down below the PCI 3 slot is a blue header. NOT the one you want.
That's for the audio ports in the front of the computer. (Front Panel)

To the right of the blue header, is a white header. This is the one you want. Front USB1. (The Front USB1 header, is below the Right/Bottom corner of the PCI 3 slot)

Note that there are 5 pins going along the top of the Front USB 1 header, and 4 pins going along the bottom.

The missing pin, or blank spot, helps you to orient the white connector of the card reader cable.

The card reader cable's white connector also has a missing socket hole, or blank spot.

There is No slot on the header for the motherboard, and No locating lug on the Card Reader cable's, white connector.

Line the card reader cable connector's blank spot, up with the blank spot on the Front USB1 header.

This is HP Support, and the Motherboard Specifications page, for the Compaq Presario SR1303WM Desktop PC,

Scroll down the page about halfway, and you'll see an illustration of your motherboard.

(To enlarge it for better viewing, you can right-click right on it, then in the drop down menu, left-click on - Save As
Put this in your My Pictures folder.

Then go to My Pictures, and double-click on the illustration of the motherboard.
Now go below in the window, and click on the + sign to Zoom In.
Use the bottom, and side bar, to move it around to the view you want)

Below the illustration is an actual photograph of the motherboard, with no hardware components installed.

The Black connector that goes to the circuit board of the Card Reader, plugs in like this.

There are four wires across the top. There are five wires across the bottom.

Looking INSIDE your computer, TOWARDS the Card Reader circuit board, the four wires go on top, when plugged in. (Not shouting)

Again, looking at the back of the Card Reader, the color code of the wires on the top, going from Left to Right, are:
Thin Black wire, Green, White, and Red.

Wires going along the bottom, starting from Left going Right,
Thick Black wire, Brown, Blue, Yellow, and Orange

How to install a sd card reader on a Dell Dimension 8200 PC Desktop? no 4 pin usb on motherboard?

I managed to install a card reader on my Dell Dimension 8200.

The main problem is that the Dell motherboard does not have the correct USB pin. This is a 9-pin MoBo USB header.

The quick answer is I installed a USB card with an internal port.

Secondly I reverse mounted a powered 4-port USB hub in the spare 3.5" bay.

Third, I purchased 2 USB 5 pin male to usb leads...

You cannot buy a USB card with 2 internals and do away with the 4 port powered USB hub because the card reader does need to be connected to a powered USB port.

for more info see this...

Card reader

This type of card reader is powered from the usb table so you will need to look for a usb header on the motherboard to plug it into. The header will be a 10 pin header ( but pin 10 is missing! ) so it is top row 4 pins, bottom row 5 pins, from left the connections are red, white,green,black, & no connection.
The power plug used to connect the card reader is the power plug normally used to power the floppy disk drive. come back to if problems still persist ?

  1. Clean cooling components that have become clogged with dust. If beeping persists, continue to the next step.
  2. Remove a memory module. If the PC stops beeping, the memory module may be bad, is the wrong type of memory for the motherboard, or was not fully seated/connected. Try reseating the memory into the socket to see if a connection was the problem, otherwise replace the module. Remove each memory module, replacing the one that was previously removed. Once all modules have been checked, if beeping persists, continue to the next step.
  3. If your computer has a graphics card, remove it. If the beep code changes or continues with the same beep pattern, the video card may still be good. reseat the video card into its socket and continue to the next step. If the beep code goes away, the video card may be bad. Try reseating the video card, making sure it is fully locked into the connector on the motherboard. If problems persist, replace the card.
  4. Remove a PCI card. If the beep code goes away, the card may be bad. Try reseating the card into its connector on the motherboard. If problems persist, replace the card. Remove each PCI card, replacing the one that was previously removed. Once all cards have been checked, if beeping persists, continue to the next step.
  5. Disconnect hard drives and CD/DVD drive cables (IDE/ATA) from the motherboard socket. If the beep code goes away, the cable or socket is probably bad. Look for bent pins inside the IDE socket on the motherboard and straighten any bent pins. Try reseating the cables into the connectors. If problems persist, the drive itself may be bad and may need to be replaced. Disconnect each drive cable, replacing the one that was previously disconnected, until all have been checked. Once all connections have been checked, if beeping persists, continue to the next step.
  6. At this point, the problem probably involves the motherboard or processor. Make sure any jumpers on the motherboard have not fallen off their pins and into the case. Make sure jumpers are set correctly.

Imstalling internal card reader

Well, installing an internal card reader without a spot on the motherboard, is a little hard to do. I would suggest buying an external card reader. They are a little cheaper, and a lot easier to setup and use, since they just connect to a USB port which all computers have.

Are you trying to install the Dell Media Card Reader? If so then the other end of the ?FlexBay USB cable that plugs into the card reader goes into a small rectangular connector towards the back of the motherboard. Specifically orient as follows; place the computer on its side, the power supply to your left and the front of the computer facing towards you. Starting at the back of the motherboard next to the power supply follow the back edge of the motherboard till you come to the approximate center of the board. About an inch towards you there will be a rectangular connector the FlexBay USB cable end should fit into. If this isn?t the cable from the Dell Media Card Reader let us know and we?ll try to help, otherwise please don?t forget to rate this posting.
