Well,you already have a DVD burner in your machine, and A DVD ROM refers to memory.. you just need to download the upgrades available at Compaq's website. find out which Cd/DVD burner you have by downloading a marvelous freeware program called Belafrc Advisor, which will list all hardware and sofware on your
computer, compete with versions and access codes. then go to

Try un-installing the adobe acrobat reader program and reinstalling it. If you have XP it is in ADD/REMOVE programs in the control panel. If you have Vista it is in Programs and features in the control panel. Then go to adobe's website and download the newest FREE Acrobat Reader. Make sure you un-check to get the FREE toolbar, as they are usually junk and cause more problems then they help.

notepad is not meant for viewing formatted html or other help files other than TXT files.

You may have accidentally changed an association.
to change it back for html lets say then right click on the file then use "open with" then "select program from list"

when the list opens scroll down and click "internet explorer" and tick the "always use this application" box
