How to solve those errors:
Go to the manufacturers website and search on the Knowledge Base or support or FAQ they (call them differently) and do a query like "general protection fault" or "0005".
the one of MS is at http://search.support.microsoft.com/kb/c.asp?fr=0&SD=GN&LN=EN-US
In this case it usually occurs when printing so I will check the latest driver for the printer.
Also at download.com is a program called regclean 4.1 , it's a registry cleaning utillity (there are more) I use that every once in a while if I suspect the registry got corrupted.
Sometimes reinstalling the app (with it's service packs)helps.
If you update the system, apps + service packs genarally (90%) you dont have problems.
And make sure whatever you are installing is a 32bit program (16 bit programs tends to mess up a lot more than 32bit).
