"Window protection error" on Win98 startup

"Window protection error' on Win98 startup
Recently I bought a used HP L1502 15" LCD monitor for use with my old faithful PI-180mhz.  It was working well.  The only drawback was the display adaptor was not able to fully utilised the native resolution 1024x768 of the LCD monitor.  No complaint.
Later I decided it was high time to upgrade to faster CPU.  I bought a  partial system - PIII-933mhz, 256MB PC-133 SDRAM, MSI-6368 motherboard, with HDD.  It was working perfectly on Win98 when I bought it.
Back home, I reformatted the HDD and reinstalled Win98 afresh.  After all OS files were copied and system reboot to run Win98 for the first time, it started to search for installed hardware.  I saw something like "L1502 .....monitor" displayed on screen for half a second, it proceeded to search for driver to install "Plug and Play Monitor".  At this point the screen blackened off, then it displayed "Window Protection Error - you need to restart system.  Press any key to continue".  I pressed a key, it rebooted and ran the same sequence and hang at the search for driver to install "Plug and Play Monitor" screen with the mouse pointer freezed.  I rebooted many times, sometimes it paused at  "Window Protection Error" and allowed reboot at touch of any key; sometimes it completely freezed at search for driver screen not responding to power button but only to reset button.  A few times, I press 'tab' key then 'enter' key immediately after seeing the "L1502 .....monitor" screen in an attempt to cancel the search for "Plug and Play Monitor" driver action, I managed to reach the 'Welcome to Window 98' screen but system would still freezed after that.  
I pressed F8 to boot up in safe mode.  At 'My Computer'- properties- device manager, I did not see monitor on the list.  So I cannot update driver manually for the monitor.  At 'Display' - properties-setting-advance, there are tab for general, adaptor and performance but no tab for monitor.  Under adaptor, I changed it with the display driver downloaded from the motherboard manufacturer (MSI)website.  I also install Chipset driver for the motherboard.  All done to no avail.
As last resort, I wiped off c: clean and install Win95OSR2.0  It worked!  Win95 installed did not recognised the L1502 monitor, it dumbly installed as a standard VGA adaptor with a Plug n Play monitor and all other hardwares without a hitch.  Subsequently, under 'My Computer'-properties-device manager I updated all the drivers.  Now it works perfectly but in Win95 and showing CPU  as Pentium Pro instead of P!!!.
How come an older OS can work while a newer OS keep dying on me?  The Win98 was smart enought to recognise the new L1502 but did not allow manual intervention to complete the driver installation.  The Win95 was dumb but at least it set things up and running to allows subsequent update.
Now my question is:
If I install Win98 over Win95 now, without HDD reformat, will it only upgrade OS while keeping all working installed drivers intact?  In other words, will it work and not revert back to square one - with all the window protection error?

If it does revert, what is your suggested solution to help me run in Win98?

    I would say you should have no problems and I'm guessing the error message was probably random, meaning something went wrong at that moment.

    Anyway, in Safe Mode you could have tried the Add New Hardware wizzard in Control Panel.

    In conclusion, I would say go for it!

    I agree with Zee.
    You should also down load the L1502 drivers from HP and Install them in safe mode, that way when when it comes up in normal mode the proper drivers will be available. The reason the monitor worked the first time is because Windows used the drivers associated with the original monitor because nothing better could be found but now your new install realises it's dealing with an unknown and cannot go forward. You could get around this by using a conventional, your old, monitor for the initial start up and then swap it out again and Windows would probably be happy.

    Here's a link to the HP drivers.

    Thanks you for your prompt reply.

    Blue Zee,
    Under safe mode, if I remember correctly, it does not allow to start the "Add new hardware" wizard.

    I have downloaded the L1502 driver from HP.  I have it installed the 1st time around on my P1-180, it cannot fully utlilised its LCD resolution due to limitation of the adaptor.  On the P!!!-933 in safe mode, I cannot find monitor on the device manager list so cannot update with HP driver.

    I have also thought of using the old monitor to start new Win98 installation, then change over to L1502 but unfortunately I had given it away for some time after I got the L1502 working on my P1-180.

    Does anyone has in memory of experience on installation of Win98 over Win95 whereby the Win98 recognise the older Win95 and installed devices with their respective drivers, and will not overwrite existing installed drivers with its own version of drivers instead it will prompt user to select if it find its own version is newer than the installed version?  Or does it has an uninstall option to revert to the previous OS if the installation does not turn out the way I want?

    You're probably right when it comes to the wizard in Safe Mode. To be honest I didn't even try it, but thinking about it confirms your thoughts.

    AFAIK, when upgrading from 95 to 98, some drivers will be updated, others won't. I believe if drivers on CD are older, the installation will skip and keep your current ones.

    If you upgrade an existing Windows installation and choose to save system files, you can uninstall Win98 and revert back to your previous version of Windows, provided you haven't used the Drive Converter to convert any drive on your system to FAT32 and you haven't installed disk compression since you installed Win98.

    But you should convert to FAT32. It may be an option not to convert, see how it runs after upgrading and convert only after everything being OK.

    Sorry for the delay in reply.  I waited for a free weekend to try things out.  I took the plunge in install Win98 over Win95.  
    It revert to the same old problem.  Luckily, Win98 allowed me to uninstall perfectly back to Win95.  Blue_zee you are right on this point.
    Next, I took out the old 2Gb HD with Win98SE in it from my old P1 box and connect to this new box as master.  (I suspected the new pre-owned HDD might have unmarked bad sectors)  Booted up...then it reported a series of new found hardwares and successful searched and installed driver for a few.  It did not recognise the particular on board display adaptor nor the HP LCD monitor but there are a standard display adaptor and a standard plug and play monitor on the device manager list.  I manually installed the driver for both and it worked.  Now I have Win98SE running in my P3-933 box working well with my HP LCD monitor but from a old small HD as master while the bigger newer HD as slave.  This gave new meaning to backward compatibility as oppose to forward new technology.  Still this is not what I wanted -  a fresh install.

    Thanks for the feedback.

    IMHO, you found yourself a nice workaround for the problem.

    I agree, it's not what you wanted, but...

    If the master HD is as fast as the slaved one, nothing was lost.

    If it's slower, you can improve it by running "heavier" software from slave and also by placing the swap file there.

    That can be done in Control Panel > System > Performance tab > Virtual Memory button.

    A small improvement can also be achieved with a fixed size swap file, 400-600MB if you have thatv free space.

    If not, keep "let Windows Manage".
