I am trying to figure out if the followiing part: C59S147-06493 is the eathernet card to my hp pavillion a1203w desktop computer and if hp sells just that part

If the NIC card is built-in you need to buy a seperate NIC card that can be inserted to the PCI-e slots of your computer's motherboard

Check that the little tab on the card is all the way forward, toward the contacts or removed completely.
Try another card to see if you get the same condition.
Try the card in another computer or another card reader.

Hi,
Here's a manual to guide you. click here: HP Pavillion a1519h Upgrading and Servicing Guide
Hope it helps.

If your unit blue screens whilst doing a recovery you have either bad memory or a failing hdd. Access the bios F10 select diagnostics hdd and test

your wireless eathernet card has went bad.

If ethernet previously worked with this card and driver, issue is not the driver unless it has become corrupted.  In device manager, uninstall ethernet card and then reinstall with driver (assuming you have it).  If card does not work with reinstalled driver, odds are you fried the card.

You could try the card in another computer if you have one.  In the meantime try another ethernet card if available.

The specs for your system's motherboard say it has an 8X AGP slot. Here's a page at Newegg.com (just as an example...I do lots of business with them, but you can search for other suppliers) that lists all the cards they sell with resolutions up to 2048X1536. Once you have a list of models and chipsets, you can compare and pick whichever best suits your needs.

I had a similar problem not long ago. The SD and SDHC standards are different. SD only goes up to 2GB, and SDHC (high capacity) goes higher than 2GB. THe problem is that SD card readers aren't capable of reading SDHC cards, even though the card will physically fit into the card reader slot. When you insert an SDHC card into an SD card reader, the reader attempts to read the format, and locks up the OS while trying. You'll need to get an SDHC card reader and use it separately like through a USB port or something.

Don't throw out that computer or replace any components just yet.

After much trial-and-error, I finally figured out the solution for this common issue with certain HP Pavillion models. It turns out to be a design flaw with the front-panel memory card reader. Somehow the card reader's firmware gets scrambled, and it prevents the computer from booting. You can test this on your machine by temporarily disconnecting the card reader cable at the motherboard header. Voila - I'll bet you $1 that your computer will now boot!

The solution is buried deep inside this HP tech support document. The card reader firmware needs to be reset.

Here\'s how to fix it once and for all:

1) With the computer power unplugged (duh), open up the case & disconnect the card reader cable at the card reader itself - NOT the end that connects to the motherboard header. Make sure the cable end is not touching any metal components before proceeding to step 2 (another duh).

2) With the cable still disconnected, fire up the computer. The tech support doc says to let it boot into Windows and stay there for about 5 minutes.

3) Shut the computer down and reconnect the cable to the card reader.

4) Turn your computer back on - your memory card reader will work and, most importantly, the computer will no longer hang at POST!

I suspect that when you fire up the computer without the cable connected, the card reader is designed to reset its firmware by grounding out through the case - sort of like a CMOS Reset jumper on a motherboard.

I hope this solution is helpful to others.
