Modem disappeared in device manager - PLEASE HELP!

My internal modem was working fine after upgrading to XP.  It's been about a week now.  I still have WIN98 on my other hard drive, and that was working fine as well.  Now both the WIN98 and XP OS will not dial up to my ISP.  When I go into device manager, there is no modem listed.  When I go to the dial up settings, it shows my U.S. Robotics V.90 56K modem, but it says that it's not installed.

I checked all connections and they're fine.  I even tried pulling out the modem, starting the computer, shutting down, re-installing, and rebooting, but this didn't help at all.

Can anyone suggest what the problem could be, or how to better diagnose what's happening.  It sounds like my modem just up and died, but it's hard to tell. 

If it is the modem, what type should I get to replace it (internal preferred).  I've got an XPS-R450 which was upgraded with the Powerleap 1.4 GHz Celeron, 512 MB RAM, Santa Cruz Sound Card and Radeon 9200 AGP video card.  Please help with diagnosis or replacement options.  THANKS!!

Calabs,

Thanks for using the Dell Community Forum.

I'm not sure if having two operating systems, even if they are on seperate drives, isn't part of the problem.  Just to make sure, can you pull out one drive, boot the system and see what happens.

Thanks Michael,

I will try the disconnect one of the HDs to see if that helps.  Is there any way of testing to see if it IS a bad modem?  I seem to recall before moving to XP that there was a couple of times where this happened (When I got a connection failed).  At this point the connection manager kept loading over and over again.  Very strange!  Would completely uninstalling (software and hardware), then re-installing help?  Pardon my panic, but I'm without the Internet (at home), and family members are getting very nervous!

Thanks again!

Calabs,

I'm not sure why either.  Nothing is making sense here and I'm just offering a suggestion other than replacing the modem which may not resolve anything.

Thanks Michael,

Well, when I boot up with the WIN98 driver, it doesn't even recognize the XP drive.   The 98 drive was formatted in FAT so it will not see the XP drive (formatted differently).  Why all of a sudden would it not see it after a week of running fine?  That's what's confusing to me.  Doesn't even show up in the device manager as being installed?
