i just replaced a motherboard, asus a7n266, and i got everything to work fine. I took out the hard drive, put it into another computer and i couldnt access the files i wanted so i put the hard drive back into the asus computer. now every time i start the computer, a message from the bios comes up and says "the system intruded, chassis opened or tempered before. please check the system." no matter what i do this message comes up and i cant get into windows. help please!!!
