can't run properly at 100fsb, why?

[fastvideo]

Asus K7M m/b with slota tbird 700.km132 bios.
can't install some cd (ex. office 2000), can't run setup.exe.
set fsb to 95mhz, same cd can install no problems. after installed set it back to 100mhz, program runs ok. even if i use 10x9 @900.
what is wrong with this computer, anyone saw this kind of problem?

any ideas????

Wow. that does seem a little strange although I don't know if I understand your question correctly. You are saying that your PC forces you to lower fsb in order to install a program but once it is installed, you can run it ok with the fsb back at 100?

yes, don't know what goes wrong, anyone can help?

maybe your cdrom drive or hard drive is defective and can't handle 33 pci, but works on 31.677? wierd, as that shouldn't happen. maybe bad ram? set it to cas3

it seems i have to use the older version of via drivers.
make a clean install with the drivers on the m/b install cd, looks like it solved my problems.
i can install office 2000 now. no more setup errors.
