I have a PC running Windows 7, and I'm using a USB external dial-up modem to connect to the Internet. However, once I plug in the modem, Windows displays a blue screen not unlike the one displayed by Windows Vista which contains text like dump physical memory. Can anyone help me with this problem?

Can you turn off the computer, plug in the modem and then boot up? Also, what is the stop error you get? – heavyd Feb 26 '10 at 20:44
what model modem? Did you verify it is Win7 compatible and load the drivers before pluggin the modem in? – BBlake Feb 26 '10 at 21:10
Post your blue screen of death info. It should give you the image name of the faulting kernel-space module. Also "Windows 7" and "Dialup Internet" are kind of oxymorons. I mean seriously, you're using Windows 7 to "dial up" to the internet?? – Apr 15 '11 at 9:44
Honestly, I do fall back to a hardware-based USB dial-up modem when a high-speed connection is not available. :P – bwDraco Aug 16 '11 at 0:54
You can use… to get info from previous blue screen crashes. – Ben Richards Aug 16 '11 at 1:09

There is lot of what is wrong.

  • Driver for USB (try latest from manufacturer of your motherboard)
  • HW problem with USB (try connect another device to same USB port)
  • Driver for that modem (try lates from USB modem manufacturer)
  • HW problem with modem
