Here's what I need help with.

I have a HP Pavilion a1223w. It has not been modified in any way, so it's just factory stuff.

The problem is, my motherboard uses PCI slots, and I need PCI-E so i'll be able to upgrade the graphics card.

I wanting to upgrade this machine to be able to game on it. Maybe not some of these high end games but I want to get it to these specifications:

This is what the game requires. The game is Warhammer Online Age of Reckoning

Ok, so I need to upgrade the motherboard firstly so I will be able to use these graphic card since i will need PCI-E slots.

I'm guessing i will also need to upgrade my power supply.

The bottom line, i need help choosing what kind of motherboard and power supply i need to get and what will fit my computer. Once I get those I know what to get for RAM and graphic card.

Sorry for the long post, I wanted to make sure i was clear with what I need help with. And thank you again to any one who can help.

This might not be easy because I don't think that HP uses the ATX form factor. Many of the motherboards mentioned here are ATX boards, which has holes in certain places that match the back board it rests on. I'll have to look deeper into this one.

If your power supply unit is below 450 watts, you may need to upgrade.

Your current mobo is an mATX one, so you can fit any motherboard of that form factor. You'd need a new one, as well as new RAM and a new video card, as well as a new PSU. I'd also recommend upgrading your CPU while at it. You could reuse the HDD and DVD drives from the HP, as well as the case itself.

It'd help if you specified a budget, as well as your location. We'd then be able to recommend the parts you would be able to buy.
