I've  just got myself a Acer aspire 1810 note book which since ok for now
its  working fine.  but  I work like  to create  some sort  of  backup of
the system  for  if  things starting  messing  up?
Since  the system don't  come  with any CD / DVD  reader or writer .

Acer Aspire 7736G
Windows 7 64 bit.
Philips DVD-R (x16 speed) discs
Hangs on the verify stage.

In the upper area of the keyboard is a button with the letter P  on it.  I
programmed this once to open the Google
chrome browser. I cannot remember how I made this setting. What do I have to
do to change this to another program?
