Got a FreeLan 802.11g wireless

The wireless card is most likely a PCI card. The PCI slot is the largest white slot on the board.

you can buy just about any PCI NIC card from ebay or even walmart and they should work. make sure they are compatible with your OS. it will say on the box.

to connect wireless to desktop you need a wireless add-on card which is connected to pci slot in your motherboard after inserting the add on card you need to load the drivers then restart the computer

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.

Since this desktop PC doesn't have a built-in wireless card installed, you have two options to get this computer connected wirelessly.

Option 1:
Install a PCI Wireless Adapter (example here)

Option 2:
Install a USB Wireless Adapter (example here)

Either options will work fine. Good luck.

As long as you have an empty PCI slot (white) you can buy any brand wireless card or even a USB wireless adapter

The Compaq Presario SR1630NX desktop computer, has a PCI-Express x16 slot on the motherboard, for a PCI-Express graphics card.

The Presario SR1630NX came out in 2005.
PCI-Express 2.0 technology came out January 15, 2007.

The Presario SR1630NX uses the PCI-Express 1.1 technology.

You can use a graphics card based on the PCI Express 2.0 technology, however.

PCI Express 2.0 is Backward Compatible with PCI Express 1.1

You just won't get the full capability, of a graphics card based on the PCI Express 2.0 technology.

Will you notice?

NO

Yes.

Any PCI Network card will do the job - the only choice you will have to make is Wireless or Wired!

If wired - go for any 100/1000 card. IF wireless go for "Wireless N"

Well virtually ANY PCI video card from that era will work... NVIDIA have great cards say in the old FX series.

Yes you can.Need more help?
