Try contacting your motherboad manufacturer about a replacement chip. If it is under warrenty they might exchange it. If they don't, BIOS chips don't cost that much; maybe around $10.
Personally I would wait until fall of this year. A lot of new stuff is coming out including the BTX formfactor, PCI Xpress, 64-32bit extension CPU's. The next few months are going to be quite interesting in the hardware realm (as if it already weren't ;) ).
