New MB , Memory and HD. Unable to load Win 2K due to only drive SATA and lack of drivers for SATA.
Loaded WIN98SE - all working fine. for one day.
Power on system , passes memory tests and hangs before determining hardware setup. Unable to get into setup mode.
Old keyboard but tests ok on other system.
Suspect bad Mother board. Is my theory coorect ?

probably not. first thing I'd do is check all connections, reset the BIOS, try just 1 stick of ram at a time, only have the HD and video card installed. After that I'd unbolt the MB and set it on cardboard to make sure there isn't a ground problem.

but you can get SATA IDE drivers here...

Thanks to all who responded. The bug was a cdrw that I had moved to the new system from my existing system. Was working good in the old system moved to new system and it hung the BIOS in POST. Moved back to original system and it failed there also in the same manner. The wonder of electronics !!
Now to move on to the SATA driver problem.
Again THANKS for the hints and help.
