Peter, Im assuming you replaced the motherboard but retained the harddisk
and its information? Is the soundcard you're using on the motherboard or
external? What operating system are you running?
Remember that changing a mobo is a pretty big undertaking for any OS.
Windows will discover the new devices (chipset, sound, serial, usb, etc) but
it doesn't remove the old ones. This can cause conflicts that can cause
lockups. There's a simple solution for either 95/98 or 2000/XP that you
should follow each time you change platforms but not OS's.
*** With Great Caution!!***
With Windows 95/98, boot the pc into Safe Mode (Pressing F8 when you see
Starting Windows 98 will give you a menu, you'll see safe mode) and then go
into the Hardware manager(right click My Computer, click properties, and
click Hardware or Device Manager). Expand each one of the device sections
and remove any devices that you are 1. Certain are no longer there or were
never there, and/or 2. Devices that are grayed out. Windows 98Se was
NOTORIOUS for putting what I called shadow devices into the registry. A
brand new, newly installed Win98Se box would show for instance 3 CDRom
drives when there was only one present. Many PC manufactures (Dell, Gateway
and HP for sure) use images to blast out new pc's. Some contain devices
that others don't, but the devices were in the image, therefore they show
upas Shadow Devices. If those devices are not there, they still maintain
memory allocations and registry space. Both of which can cause conflicts
with present devices. Once all "shadow devices" are removed, reboot the pc.
If you errantly removed any pertinent device, the Add Wizard will start and
prompt you to reinstall any missing components. Once its finished, restart
it in Safe Mode again and check the Manager to see if they're all cleared.
Then see if that cures the problem.
The scenario for 2000/XP is similar but with different approach. To see the
"hidden devices" you have to follow certain steps. They're available at
this MS KB Article:
Follow the steps there and repeat the same thing. There's one exception.
The section called "Non Plug-N-Play Drivers" should probably be left alone.
That's a section of drivers as opposed to devices. Its not a good deal to
mess with those. Additionally, the sound section does contain several items
pertaining to certain Codec's from Microsoft and various vendors. I don't
recommend removing the Codec's, but the devices are safe to clean out. I've
found something in there be in nic's, extra monitors, cdroms, sound cards,
etc each time I've changed a Mobo. So give that a whirl and let me know how
it turns out.

Subject: [RTTY] Help with keeping RF out of PC
Content-Type: TEXT/PLAIN; charset=US-ASCII
I had a little, um, "incident" a while back (T-day weekend) which caused me
to have to replace the Athlon/Abit KT7A combo with a Duron/Soyo Dragon
somethingorother. Everything works, but now the MMTTY engine (under N1MM
Logger) will stop decoding and lockup.
I sent the MMTTY error message to the MMTTY list but since it only seems to
occur on transmit, the conclusion seems to be that RF is getting into the
My thinking is that it's the soundcard itself, since 1) I can still transmit
after MMTTY goes QRT (IC746PRO in FSK via RB+) and 2) when I re-init the
digital interface window in N1MM Logger MMTTY sometimes can't open the
soundcard (per the dialog that pops up).
It should be mentioned that I rerouted and generally tidied up cabling
behind the desk in the radio room at the same time I was doing the rebuild,
so it's entirely possible that this is part of my problem.
So, what I need is a primer on keeping RF out of the PC. Pointers?
