Front Panel Not Detected

Another post? I suck at building computers.

 

So when I start my computer it says the aforementioned error that is in the title, any ideas? All of my front panel connectors are plugged in and such, so I should not have a problem

You shouldn't have to have them plugged in at all. What kind of computer is this?

A dell Optiplex 755, with no power switch on the psu itself

Hmm, are you able to boot bast it or are you stuck at it? Can you get into the BIOS?

 

When it says front panel I wonder if it's referring to Chassis Intrusion. This being the side panel. Open the side panel and see if there's any little black push button or switch that interacts with the side panel.

 

If this is wrong try unplugging and replugging the cables that go to the front panel.
