Win98 PC Crashing on modem handshake

By jdep ·
Fault Presentation: Computer crashes completely when the modem attempts to handshake with any ISP.
System: Upgraded PC clone/450 Pentium II (A)/64MB RAM/ Win98/ Intel
Motherboard/ ATI Rage Pro AGP 2X/ Sound Card SB 16 PCI/ Modem 3Com PCI/.
Clean Installation no errors showing anywhere in systems device file, no IRQ
conflicts....nothing!!!. Machine looks absolutely spot-on and works perfectly at
94% system availability.
Problem: When an attempt is made to dial out the modem kicks in, dialsout
perfectly and attempts to handshake the dialled location. The handshaking
'warble' continues for about 8 seconds and...CRASH.....everything locks up....and it's a real switch off jobbie - not just Ctrl-Alt-Del and free up the application.
Actions to date:Two clean re-installs of Win98, substitute everything (all PCI
cards) except motherboard and processor.
I am certain the fault lies with the motherboard.
Has anyone else had experience of this fault.
All suggestions would be appreciated - Thank you all in advance.

Win98 PC Crashing on modem handshake

Have you tried using a different modem driver? For example, try installing the modem as "Standard Modem" and make sure that when you test dial up networking that you have selected that driver to connect with. It might help. It would also be helpful to know just which Intel mobo you're using as we try to help you with this problem.

Hmm. I have a few suggestions to tell you what fixed the problem for me when I had the same thing happen a few years back using a WinModem.

I did three things:

(1) Went to the 3COM (USR at the time) site and downloaded the latest drivers for my exact model of model. This is IMPORTANT, modem drivers, I have found, are nearly as **** as video card drivers. You have to have the EXACT model for what you have.

(2) Then I went to the Microsoft website and search for an updated winsock.dll file. I installed it in the C:\Windows\System directory. (Windows Sockets, remember - this is the file that remote communications on windows systems relies on. Windows Sockets are used to communication with other machines).

(3) Just for the sake of completeness it so happened that a new version of DUN (Dial Up-Networking) was released by Microsoft so I upgraded to that as well.

After all this, my modem has worked flawlessly since then.

I think it was my winsock file that was some how corrupted or just plain outdated.


If all that fails,

Switch out the modem entirely with another modem (they are cheap now - a 56k modem of GOOD quality is not even $60, and that's a GOOD one).

Other suggestions, comments:

(1) Is your modem a stand alone or one of those built in motherboard / soundcard deals. If it is - disable it and get a separate "standalone" modem.

(2) How old is your motherboard? Did you go to the motherboard's site and look up FAQ's or updated drivers for it? What about the BIOS? Maybe the BIOS needs updating (be VERY careful if you pursue this though, the wrong BIOS can literally fry your computer dead).


Last resort,

Get on the horn with the motherboard tech support people.
