Upgrades rarely go smoothly, any issues with the old OS are usually carried over. Short of doing a clean install of 2K, I would check for updated motherboard drivers for 2000 (you would do that for a clean install as well). Then new 2K drivers for the modem and sound.
I have recently upgraded from Win 98 to 2000 and everything was fine. I then went to the Microsoft site and installed SP4 since then I have no sound from my soundcard and my modem is not working properly. I can dial up fine and a connection is established fine but then if I go to a site only about 1 or 2k are uploaded and then nothing further happens. The connection is still there but no further data is uploaded. I got a patch from Microsotfs site but it has not worked. I have also tried to update my modem driver but the problem is still the same.
Can anyone help me on this?
I'd really appreciate it.
