Hi, welcome to TSF
System specs for the HP Pavilion a522n Desktop: http://h10025.www1.hp.com/ewfrf/wc/...roduct=407147&lang=en&cc=us&docname=c00091508
Your computer is quite old and uses onboard graphics (Intel 82845G) which is a chip on the motherboard, not a proper graphics card.
Most computers from a few years ago use the AGP slot and newer computers use the PCI-Express (PCIE) slot. The only expansion slot that your motherboard has is PCI which is not really suitable for graphics cards as it is very slow compared to AGP and PCIE. As well as being slower, PCI cards are more expensive than the newer AGP/PCIE cards.
The Nvidia GeForce 6200 PCI supports Shader 3.0 and DirectX 9 ($78 plus $7 shipping - http://www.newegg.com/Product/Product.aspx?Item=N82E16814139034). According to the Newegg spec sheet, your computer needs to have a minimum 250W power supply unit (PSU) to run this card. Remove the side panel from your case to see the label on the side of the PSU and post back with the make, model and total watts. It's adviseable to upgrade the PSU whenever you install a new graphics card, especially on an older computer where you're upgrading from onboard graphics.
You might find that it's better to buy a new entry-level computer rather than spending money on a PCI graphics card and new PSU. A new computer, even at the lower end of the price scale, will perform better than your current PC.
