how you guys, am kinldy asking, does the hardware for advnet 5712 meet the requirements needed to install need for speed carbon, quake 4? please help.especially that advent is vista.

There's a wiki page that shows how to run Need for Speed Carbon on Vista with system requirements:

How to run Need for Speed Carbon on Vista

Here's the system requirements for Quake 4:

English version of Windows 2000/XP
Pentium 4 2.0 GHz or Athlon XP 2000+ Processor
512MB RAM
8x speed CD-ROM drive and latest drivers
2.8GB uncompressed hard-drive space, plus 400MB for Windows swap file
100% DirectX 9.0c compatible 16-bit sound card and latest drivers
100% Windows 2000/XP compatible mouse, keyboard and latest drivers
DirectX 9.0c included
3D Hardware Accelerator Card required
100% DirectX 9.0c compatible 64MB
Hardware Accelerated video card and the latest drivers.

Again there's a link to look at if you have any problems playing on Vista:

Tweak guide, Quake 4

You'll probably need to drop some of the settings for the visual effects, as the intergrated graphics of the
laptop aren't as good as a dedicated graphics card that you would get on a desktop pc.

thanks a lot man, i will try to go to the links you have posted me.
