Compaq SG3540IL XP Driver
I recently get this PC for service and at the time of installation of driver I come to know that HP or Compaq doesn't provide driver link for XP so somehow I mange the driver and that's why I share the drivers here in this blog so friends here they are -
All the links lead you to mediafire. which is free file large sharing service. Although HP/Compaq have the rights of this driver.
