You are able to view your devices driver version within Device Manager (To access this right click on my computer and go to "Manage" and then select "Device Manager")
Here you can view your devices and if you right click on one then go to “properties” Followed by the “driver” tab you will be able to see the driver date and version.
Regarding updating these drivers, it is a good idea to either enable Windows Update or to run it manually as and when you wish to look for updated drivers.
When Windows XP was released in 2001 Microsoft introduced Windows update at the same time. Windows update does not only search and download the latest updates for windows but it also has a huge collection of drivers from all of the hardware manufacturers.
Chances are if there is an updated driver for your installed hardware then it will be available via Windows update.
The reason I'm trying to update my drivers is because I've been getting a BSOD. I was told not to use device manager but rather go to the website and download the drivers. When I go to device manager which "drivers" should I download..disk drivers, system devices or what? I think windows updates are 1 reason that I'm getting blue screens.
