I have been using an Acer Aspire 5742G notebook for over 1.5 years and though I have tried to find updated drivers for my notebook's drivers, the Acer Updater installed never finds one, though some new drivers are listed on the Acer India website. Also, I have run the H/w Detection tool to verify which makes of components are installed on my notebook, and wanted to download and install updated drivers manually. This is particularly for nVidia Drivers which are "old" compared to nVidia's website which has recently released version 306.97 which mentions the graphic chip nVidia GT 420M installed on my notebook.
Is is safe to update drivers from OEMs like nVidia, and whether I should download & install "newer" drivers from Acer India website for other components such as LAN, Bluetooth, or Wireless LAN, etc. Would appreciate advise from knowledgeable folks. Thank you.
