bizarre problem with xp pro

I'm running xp pro with a 56k modem.
After shuting down the computer and start it again, window won't reconize the modem, it says that is not installed properly or is busy but by using system restore then windows reconizes the modem.

what seem to be the problem??? Can it be a Virus?

sorry for the grammer and sentence structure problems, is 2AM here is canada, i spend like 5 hours trying to figure out the problem, my eyes are burning like hell, and i really needs some sleep

 

i would just go to a drivers site, look up your modem, and install the driver. reboot, and see if it works. i thin i get most of my drivers from driverguide.com. free registration. and lots of drivers for almost anything. and i'd be confident in recommending it more now than ever before because of this peculiar situation i put myself in one day.

one day i felt the need to install 2 os's unto a computer that orignally came with xp. so i added 98 to it, and of course, theres no way 98 is gonna have the drivers for all the new hardware on my computer which came out in 2003!

the modem, the video, the sound, everything was out. lol. so i went to driver guide, got all the things i could get, and man, now 98 is busting through and kicking butt! i love 98. but i mostly use xp on that computer so i rarely switch to 98 lol
