Firstly be aware that Windows XP reaches End of Life in April 2014 for more information see XP Service Pack 3 and Office 2003 End of Life April 2014. Continued use of Windows XP should be avoided. Assuming you are wanting to connect the Windows XP to the internet you should at least install XP Service Pack 3: [URL] It is also recommended to install Microsoft Security Essentials: [URL] and its latest definition to minimise the risk of having an unpatched Windows XP installation: [URL] (32 Bit) You will need to install Dell System Software: [URL]  Intel Chipset Device Software: [URL]  For the Network Controller and Video Device provide the hardware IDs as there are variants in this model. See Windows Reinstallation Guide/A Clean Install of Windows XP Step 12: [URL] As mentioned above the drivers should be downloaded to a USB flash drive using another PC.
I have a dimension 4550 o/s Windows XP Professional 2002. I have never used the computer on the Internet but notice that there are yellow question marks next to the Ethernet Controller and USB Controller. I now need to use the computer on the internet and obviously need these to work. From researching on this website I have re-installed the Chipset Driver and it popped up "found new hardware" for both. However, then when going into the "found new hardware wizard" it asks to install the software. I have tried inserting the resource CD which came with the pc but doesn't find the required software. Also, I cant get onto the internet to find the required software. Any ideas please????
