You have to be a bit careful turning off your PC making sure you still get necessary patches. Typically, the DSL/Cable modem will check for updates whenever you turn it on. For the PC: It should still regularly check for updates while turned on. Rebooting the PC may be useful to make sure all the new code is loaded. In corporate environments: Do not turn off your PC unless you talked to the network administrator first. Techniques like 'Wake on Lan" can be used to turn on the PC remotely if needed to perform backups and to patch.
A turned off PC with a BIOS password is also a reasonable deterant to protect your PC from unauthorized use. In particular at home if you would like to prevent other household members from using your PC. (note however that this will usually not protect you from more sophisticated attacks and theft)
And don't forget that this will save energy as well.
