Strange message saying "Warning! Your chassis has been opened!"

\015 This is a new PC - only 3 weeks old. Last night I plugged in some headphones for the first time. A screen came up asking for a password to do this. I thought this weird but carried on anyway. Then a green Acer came up that I didn't understand at all so I clicked it off. Everything was fine. I switched the PC off. Later switched it back on and a black screen came up with loads of gobbledegook on it and a final message at the bottom saying "Warning! Your chassis has been opened!" I never touched it! Nothing has been opened. We telephoned Acer who didn't seem to be able to help (what he was indicating should be on the screen wasn't) and accused us of opening the chassis. My husband fiddled around later and came across a screen which asked if we wanted to save recent changes. He indicated no and up came the sign on screen. We signed on and away we went. However, the sign on screen now appears to indicate that there is more than one user on the PC which is not the case as my husband and I use the same sign-in. The PC is OK as long as we keep it in sleep mode but if we turn it off, we have the same screen come back up saying about the chassis so he has to go through the process of trying to sort it out. Anyone out there any ideas except for sending it back as suggested by the Acer guy?\015

I had the same problem with an Acer desktop after I upgraded the Ram, and I tried everything including resetting the bios. I finally solve it by entering the bios and Loading the Optimal Defaults and then saving it with F10. I have not had any chassis intrution message since then
