Win95 protection error

I need consultations from people out there who have encountered such problems before:

I've assembled a Pentium 200MHz MMX computer with an Intel Motherboard, Intel CPU, ExpertColor SoundCard, ExpertColor Graphics Card and 3COM Ethernet card.

I've encountered strange problems after installing the drivers for the Ethernet Card and Sound Card.  After rebooting the system, Win95 tells me to "Reboot the system because it's in Windows Protection Error".  When
I does so, it will only allow me to goto Win95 in safe mode.

This problem goes away only when I disable either the Ethernet driver or the Sound System driver in the "Control Panel -> System -> Device Manager".

I've looked at devices in "Device Manager" and it shows no conflicts in memory/DMA/IRQ.  One of the items worth thinking about is that there's "?" device which detects a "PCI bridge" and "PCI card".

I've tried to change a IRQ/DMA values for either the Sound/Ethernet card but with no success.

For your information: It's a ISA sound card and PCI Ethernet Card.

For older version of Win95 (one that upgrade from Win3.11 to Win95), this problem pops after full installation and rebooting a couple of times.  For newer versions released last year, this problem "Win protection error" occurs immediately after Win95 asked me to reboot the
system after the installation of either Sound Card or Ethernet Card drivers, depending on which driver I install later.

If you need further (faster) information, please write to
me at lien@hpsgwh.sgp.hp.com

Ok Lien it said that because windows 95 has a protection mode for this kind of stuff because it might not want be able to work with the drivers of the ehternet card and the sound card I suggest you contact microsoft technical support and the company that made your sound card and the ethernet card.

This is more of a "last resort" 'cos there will be a tendency for
various individual companies to blame this problem on the others.

Thanks to rchou for his opinion anyway.

If you installed certain driver for this it could have conflict problem in the registry. If not, your card is give address conflict problem. Check with the manufacture of the product to see if there is an updated driver for this product.

Maybe you can try my humble tip ?
Right-click "My Computer" icon from your desktop & click on
"Properties" goto "Device Manager" & remove your soundcard & ethernet card. You will be promted to restart your computer.
Do not do anything yet.
I am sure with your purchased of the new Intel Motherboard, you are given a CD-ROM to update their hardware drivers for Windows95. So, before you reboot, standby all your Windows 95 setup CD-ROM, soundcard & LAN Ehernet card diskettes drivers/installation disks & the Intel Motheboard CD-ROM/drivers
Now, removed the Soundcard & Ethernet card from your system  by unscrewing yur system & pulling out the LAN & ISA card.
Now, switch on your system again & put the Intel CD-ROM drivers update into the CD-ROM unit & use windows explorer to goto the
DRivers update directory. Run the application to update tha hardware drivers & reboot yur system after installation to check if everthing is ok.
If the PCI bridge is ok & have no more "!" or "?" shutdown yur windows & reinstall the soundcard & ethernet card.
This should solved your problem. Post me your results !

Moonshi has managed to solve half of my problem by suggesting me
to use the "Intel Motherboard upgrade CDRom".  This has solved
my unknown "?" for PCI bridge and PCI card.. it doesn't exist

I'd have to admit that I didn't do any hardware removal of cards
during this trial.

The problem still persists after installing the sound and ethernet drivers.

Moonshi, if you feel that I really need to remove the hardware
to make it work, please voice it out again.  Thanks!
