A friend of mine has installed a secondhand mobo[gigabyte]with the existing hdd.When it boots up a message--scan bios info error--sorry we do not support this mobo comes up.When going into system it does not show the cd rom or the hard drive--or the controllers--or the mouse- keyboard etc.Thought it may be a problem with the info on the hard drive not being compatible--so used a 98 boot disk to format the hard drive--but could not access the cd rom.Has anybody seen this problem before--and can anyone help please
