Uh Oh!!! Advice Please!!

A friend of mine decided to build himself a new computer, as he has built many computers for other people, and finally decided to get around to building one for himself. He bought an ASUS duron/thunderboard board (I believe the kt133A) and had no problems setting his system up, only to discover that the keyboard would not work, regardless of whatever he did!!!(I decided to try and help, and we tried 5 different keyboards, and even switched the case and power supply....nothing worked!!!) We had all of the proper computer tools, and were both grounded the entire time that we worked on his system.

He struggled with it for 2 days, and even contacted ASUS technical support, and the place where he bought his motherboard....only to hear them tell him that his jumper settings had to be changed etc.... WELL..... after giving the mobo one last try before he branded it defective and returned it, he powered the motherboard up a few more times and alas...the keyboard ps2 connector refused to recognise any keyboard that we tried!!! As he was about to power down, snap crackle...a little fuse burned out exactly where the keyboard ps2 connector was, and now he is freaked out that the company that he bought his motherboard from may not accept him returning it because of this little fuse being burnt.

Questin is, was this burnt fuse his fault, and will the company he bought it from most likely blame him and refuse to exchange the board over a burnt fuse?? Can a defective board cause a burnt fuse???
