Guys! this is a picture of my motherboard and there is a pci card type thing at the end i don't understand whether its an embedded card or another device has to get fixed to it. The motherboard bios gives the error message that an embedded security hardware is missing. Someone who had some knowledge of computers told me that this is itself a hardware and if i close the cover of the casing it will no longer give the security hardware missing error. I closed the casing cover but still it gives the error message .
