When I shut down my computer at night, it is back on in
the morning. What do I need to do so it does not come on
by itself.

Check if an automatic power up was defined in bios setup. Thats usually in
Bios setup's power management menu (should be disabled or set to 00:00).

If none was set, your case is possibly suffering from a faulty or
misconnected power button. Usually caused by a capacitive load which
eventually triggers. Download mobo manual and disconnect the power_on jumper
overnight to test.

Also, depending on mobo involved, you might be suffering from a Wake-on-Lan
or Wake-on-Modem feature that misbehaves. These can be disabled through bios
setup and the WOL connector removed between NIC and motherboard, if any.
 
If it's a Dell PC, there is a power on schedule set up in
CMOS you need to disable that function. Hope it help!
