Question:

The desktop computer you're working on won't boot. When you press the power button, no status lights illuminate, and no fan sounds. You check the outlet and try a power cord that you know works, but it doesn't help. What TWO things are you going to do next?

A Check the I/O switch on the back of the PSU.

explanation

If the I/O switch is in the Off position, the PSU will not turn on; similarly, selecting the incorrect voltage may prevent the computer from starting, and if it does start, utilizing the incorrect voltage will have devastating results. The other two options are unrelated to the issue at hand.
