possible for sql server to be corrupted?

is it possible for sql srever to be corrupted by some misdoing of the application? (not the data or database, but some aspect of the sql server itself and its installation and integrity)

when you put a new SP, will it validate if the previous RTM or SP is integral and complete?

There is always a risk when upgrading versions or installing a service pack (even if the software is flawless, the power could go out and install fail midway), however for security reasons it is always recommended to keep the products up to date.

Microsoft produces a best practice guide to do before upgrading versions of SQL Server, many of the items would apply for updating service packs as well: http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=15220

They also have a an technet article on "Validating a SQL Server Installation": http://technet.microsoft.com/en-us/library/bb510455.aspx

And of course, the best thing to do is make a complete backup of all your databases and check the release notes to make sure non of the features you are using have been discontinued or changed in a way that would break your system.
