I just bought a game that requires NVIDIA GeForceFX with 32MB of ram or ATI RADEON 9000 series graphic cards. I currently have the following on my computer:
Graphics Card = Intel(R) 82845G/GL/GE/PE/GV Graphics Controller
  Type of Chip = Unknown Video Chip
  Video Driver = ialmrnt5.dll
  Version = 6.13.10.3510
  Updated = Tuesday, April 15, 2003 11:40 AM
  VendorId = 0x8086
  DeviceId = 0x2562
  SubSysId = 0x1601028
  Revision = 1
  VRAM = 64.0MB
  AvailableVidMem = 6.0MB
  AvailableTextureMem = 51.0MB

Intel(R) Extreme Graphics Driver

I have the basic Windows XP Home edition on a Dimension 2400 pentium processor 4. I really need help to know how to change my graphics driver so I can play the newest games and update my system.
