Ok guys. Thanks for all of your help. I've replaced my Graphics Card, memory, mobo and PSU and am wondering what you think.

ASUS P5N-D LGA 775 NVIDIA nForce 750i SLI ATX Intel Motherboard - Retail

G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-2GBNQ - Retail

Antec Basiq BP500U 500W ATX12V Version 2.01 Power Supply - Retail

Also, will I need to purchase anything like fans or anything else to get going?

Ok, so I am a complete PC noob. This is my first PC I am going to build and basically have no knowledge of what all the terminology means. Please inform me if these parts aren't compatible, or if I need something else.

Also, please don't tell me that this isn't the best combination. I know it's not. I'm not looking to have the best PC on the market. Just one that can support most games at a decent rate.

Also, some random questions.

Can games released prior to Vista be played on vista? Like Doom 3? Thanks
