What do i need to connect my Compaq Presario SR2020NX to my wireless network? ready

You mean will the Asus ATI Radeon HD6450 with 1GB of graphics memory, work in a Compaq Presario SR2020NX Desktop PC?

Yes.

The Compaq Presario SR2020NX Desktop PC has a PCI-Express x16 expansion slot.

{Motherboard illustration and photo are towards the bottom of the page}

Look at the specifications.
Scroll down to the heading - Expansion slots.

Three PCI. (PCI expansion slots)

One PCI Express x16 graphics.

NOTE*
Looking at the motherboard illustration, it is Wrong.
Shows - PCIEX1 (PCI E X1)
According to the specifications it is a PCIEX16 expansion slot. (PCI-E x16)

A PCI-Express x1 slot has 36 contact pins. 18 on each side.

In comparison a PCI slot {White} has 124 contact pins. 62 on each side.

Looking at the photo of the supposed PCI-E x1 slot they show, the black PCI-Ex1 slot is longer than the white PCI slots.

It is a PCI-Express x16 slot with 164 pins. 82 on each side.



The Asus ATI Radeon HD6450 uses a PCI-Express x16 expansion slot.

So you know the graphics card will fit. Low-profile to boot.

Power requirement:
The Compaq Presario SR2020NX desktop computer comes with a 300 Watt power supply.
(Although in actuality it's more like 70 percent of the maximum rated wattage. 210 Watts)

Enough power for the computer, and the graphics card.
ATI graphics cards do not use as much power as a comparable Nvidia graphics card.

Concerned that the Asus graphics card uses DDR3 graphics ram memory, and the Presario SR2020NX uses DDR2 Sdram ram memory?

Don't be. The graphics cards graphics memory runs independent of the computer's ram memory.

I have this issue with legacy hardware more often than I'd care to admit... this has always been helpful to me. http://www.driveridentifier.com/files/driveridentifier_setup.exe
Promise it's not a virus, just a little scan program that will match the drivers Device ID with a HUGE online database, and show you to a download link.

Being SATA and within the limitds of the MB, the HD WD Caviar will works fine

Yes it is compatible although you will need to fit your own Wifi card. There are two types of card, PCI and USB. To fit a PCI card you will need to open up the PC and install the card into a spare PCI slot. To fit a USB card you simply plug it into any spare external USB socket.

Make sure the cat5 cable coming from the modem is going to the computer and bypass the router for now.

If the computer is able to connect to the internet then you know its a configuration issue with the router. If it still can't connect to the internet then you know its an issue with the computer, might be a driver issue with the computer at that point.

Call your Internet service provider and have them tell you the steps on how to configure your router to work with there internet service.

check your connections to the monitor and pc make sure all your connections are secure. It could be a bad video card in the pc, bad cable or bad monitor.

hi im josh, friend you need to set up network connection for printer config.becoz it is different connection from your internet.try to do so.good luck.

Since youre setting up a DSL connection choose Set up broadband connection > PPPoE. You will need the username and password you were given to this account (contact customer service at your ISP for this info). Enter the info and have it remember the password. Click connect. Once Vista finds the connection, it will ask you to choose a network type (Home, Work, or Public). Select the type and enjoy. If the connection fails, recheck your username and password entries.
