Although in many/most "modern" computers the BIOS NVRAM actually is in flash, perhaps that machine uses/requires the CMOS battery to maintain the BIOS settings. If the CMOS battery is getting weak, then errors can start to occur in the BIOS settings. If that battery is more than 5 years old (and maybe regardless of its age), I'd go ahead and replace it. I've always thought it was an oversight for BIOS makers not to have standarized a way to export/import the BIOS settings (via serial port, to DOS floppy, or even as ascii printer text through the parallel port) from the earliest days, well, at least after the number of settings exceeded a dozen.
