This is the nVidia nForce220D integrated motherboard.
Firmware Rev 1006.
The problem I have is that when I turn the computer on it starts to boot up but then goes into BIOS with the following message coming up.
The system intruded, chassis opened or tempered before.
So I then exit BIOS and the same thing happens again and again. Sometimes I have to reboot the machine for up to 20 minutes to finally get into windows.
Naturally I have emailed ASUS support but as of yet I have received no reply.
Any help in solving this really anoying problem would be much recieved.
