Modem reboots PC when accessing it?

[Buickboy]

I have a K62-266 256Mb Ram. Things were going fine till a few weeks ago. When I log on to my home network, I can not access other PCs. They accasionaly see this one I am refering to here in this thread. I go to use the modem and it reboots PC. I take out the modem and I can see all other PCs fine. I reinstall the modem and it is back to not seeing other PCs on network and accessing the modem (DUN or Hyperterminal) and the PC reboots. I take out the modem and I am back to no problems with the network. This used to work for a year. I tried taking out the NIC and then the modem works. I install the NIC again and it is back to the above problem. There is no conflicts. I tried putting the modem on another IRQ but it just locks PC up? Wondering if the modem went bad or what?

Heh. I see NOBODY will touch this one, and I see why.
It's a mystery network snafu, tough to troubleshoot in person, and near impossible by email.

I won't even say I have an answer, but I will say this:
There is a lack of information here to work with.
Although the description of the problem is good, you could include much more info about your problem system;
What OS ?
WHAT MODEM ? Win modem ?

It does not really sound like a hardware problem to me,
but a software problem, or a Network configuration problem.
Obviously SOMETHING changed,,,,,,, in your network, but what ?
It could be ONE driver got changed, one setting got changed,,,,,,,,,

What are the IRQ's ....... look in MSINFO32 or DEVICE MANAGER - IRQ's and see if the MODEM & NIC are sharing an IRQ.........
If they are,,,,,,, move them to different PCI slots.

**** MY STANDARD,,,,,,, and favorite tool to free up IRQ's is to use the BIOS,,,,,,,
and DISABLE the unused SERIAL PORTS...... which take TWO IRQ's,,,,,, 3 & 4.
Disabling these two antiquated and usually unused items free's up the valuable IRQ's...... and may have your modem move to IRQ 3....... and not sharing ..............

Please post more information..........
* LAST: Try getting NEW drivers for BOTH devices, the MODEM & THE NIC,,,, and reloading them.

Jakespeare,
Thank you for taking time out to give advice. It was my first posting ever on sites like this one. I did forget to put in more detail. I am not requesting any more help... I decided to make it a modem only PC. I am giving away this old PC and wanted the person to have a modem and also be able to come back to my house and use the network for fast internet and for me to fix things. Every other PC I have been able to get both devices to work.

The PC is a Win98SE, The NIC is a D-link 10MB, and the modem is a Win modem Archetek 56K v90? I wished I had an extra modem around to swap and see if it is a hardware issue with the modem then swap out a NIC to see if the NIC was the problem. If either of these steps did not do the trick then I would be convinced it was a software problem. Oh well.. it is unusual that I do not have spare parts around. I rebuild PCs and give them away (free)to people who do not have money. So I work with a lot of outdated hardware and software!!!

again, Thank you!!

Thanks for the reply.


>> *** Archetek 56K v90 *** would be 1st on my list of things to eliminate.

> I still think that it could be / could have been some esoteric Ntwrkng protocal, or software issue.

Uh,,,, if your working on PC's, don't forget the "dump the SERIAL PORTS" tip, it's a great tool.
