I change my PC, yesterdays and even if the CPU speed, ram, video card are all better than my last PC the gsme is lagging?! I read at bioware's site that WIN XP does not correctly take Open GL (whatever that mean...) and you need to update your driver. Ok but how do I do that?

first you have to specify what type of graphics card you have in your system, Nvidia,ATI etc... Then just go to their website and download the driver designed for your card. Atleast for Nvidia you just download the detonator driver and it will sence what type of Nvidia card you have. like Geforce, Geforce 4, TNT2 etc..

Firstly you must imagine I have just isulted you for not being geeky enough.

Secondly you get the newest drivers from the manufacturers website, I'm not actually sure if the Vodoo website is still up but if not then you find some other place.

Either run the executable or after unpacking go to you'r card from hardware management and select update driver, then do a search for the newest drivers on you'r computer.

Bioware has a "Self-Help" technical forum that is pretty good about assisting with the sort of problem involved here. Infogrames is the "official" support site, but I don't have a bookmark for them.

The nature of the Windows PC being what it is, individual parts of a system may not end up optimized for gaming when you get them installed into a unit. The piece of software that sits between Windows and the hardware and helps the OS communicate with the hardware is called a "Driver" and right now the best hardware might be ATI, although they always have tons more trouble getting good Drivers working than Nvidia does.

Nvidia is a good choice for video because they keep their Drivers up to date so much better than ATI seems able to do. The 3DX people who once were so dominant with their VooDoo adapter line has gone up in smoke, and no one supports those any more, save for a few amateurs doing it for their own entertainment.

Another possibilty is that it could be a sound card problem. :(

You should really check for the latest drivers for all of your hardware: video, sound, mouse, etc. It can be a real pain, but you don't always get the latest software with the latest hardware.
