Hello Chris, my name is Dan.
I will do my best to help you, the only silly question is the unasked one.
First I suggest some basic maintenance.
Repairing permissions, pram reset followed by a SafeBoot.
To do a PRAM reset, you need to restart your machine and hold down these 4 keys all together at the same time.
‘Option’, ‘Command (Cloverleaf or Apple)’, ‘R’ and 'P' all together at the same time.
Keep them down until you hear 4 startup chimes, this is the sound that your computer makes when it starts up, it is like a boonngg. The screen should also cycle from white to black and then back to white along with the chimes.
The sound should also get louder.
This resets all of the system buses on your computer, USB, FireWire, display, ethernet and your keyboard/mouse/trackpad.
This will correct many faults but not necessarily yours.
A SafeBoot is done by holding the Shift key during startup, it takes a little longer and should show a progress bar and say, in erd, on the login screen 'SafeBoot'.
You said you had done the pram but it won't hurt to do it again, permissions are a big thing also.
Do thoes three things and let me know, please.
