Windows Explorer internal error--page faults
When boot up (and frequently at other times), I often get this error message: "There was an internal error and one of the windows you were using has been closed down. Save your work, close all programs, and restart computer."
Also get: "Explorer caused an invalid page fault at module KERN32.dll @ 014f:bff71a66 "
Also get: "Explorer caused an invalid page fault at module KERN32.dll @ 014f:bff71a66 "
smee-buddy, you should write a book ;-)

First thanks to SMEE. I am still trying to evaluate the answer to see if it helps. My system is a 33MHz PC with 16MB of RAM, running a lot of DOS programs in addition to WIN95 programs.
I am working my way through SMEE's list and am up to no. 3.
Couldn't find his site to download the antivirus programs. It is unclear which version of the antivirus programs one should get, DOS or WIN95? Also, should they be run from WIN95' DOS 7.0 or from DOS 6.22?
Some preliminary answers.
4) Problems started about 5/1/97; don't know what caused it.
5) I have over 100MB free hardisk space.
8) Uninstalling video or mouse driver not practical because they never caused problem since I first installed WIN95 in 11/96.
9) Using many DOS programs from the beginning never caused these page faults, though may have slowed system, which does not bother me.
13) Reinstalling WIN95, won't that mean I lose all the many WIN95 settings?
I will continue to work through the list, but was hoping for specific attack on the Windows Explorer problem and the conflict with the kern32.dll file, i.e., is the registry corrupted somewhere? C.M.A.

OK, I know it was long.
1st, Running "setup /p f".
The /p allow you to use other switches, in this case f.
-----
Example: setup /p f
f - This switch enables Clean Registry mode. It forces Detection to
clean the root branch of the registry before starting. This switch
is ignored when Setup is run in the Windows 95 graphical user
interface (GUI).
The default is disabled.

Answer is worth full 90 points. Smeedbud went the extra mile. I will be working on the registry because I think that's where the problem is. CMA
Meantime lets start with a basic trouble shooting guide.
---------
These are Basic Win95 trouble shooting guide, the steps are merely
a guide for common computer problems and how you can detect the
problem and fix it, some might not apply to your situation.
1)Run Scandisk(standard), run defrag(see Defrag tip).
2)Now don't say I have Antivirus and I don't have a virus
It will give you one thing out to worry about being the problem.
Run antivirus from DOS not from windows, that's what I always do,
Thunderbyte, Norton, F-Prot, Mcafee, Dr Solomon
http:/www.shareware.com
http://www.mcafee.com
http://www.thunderbyte.com
In Shareware.com
Search for ANTIVIRUS in the search engine, download the Norton antivirus
09nav96.exe
And search for
fp-224c.zip in the search for F-Prot antivirus.
Thunderbyte and Norton are downloadable from my site.
To run antivirus from DOS, download the .zip file and expand it with Winzip or any unzipping software then extract the self extracting file
in a temp folder, copy extracted files to a NEW floppy(out of the box), write protect the floppy by sliding the tab upwards, exit from windows to MSDOS or start computer
in DOS, type A: then type
Scan c:/ all if you are using Symantec(Norton)
Type F-prot to run F-Prot.
Type tbav to run thunderbyte.
If virus is found, check all your floppies for viruses, check other
computers that you exchange data or programs with.
Note: Window antivirus might not be able to kill the virus.
The best detecting antivirus is Thunderbyte but as a shareware will not kill viruses, Symantec not as good in detecting but the shareware version does kill viruses.
Windows antivirus merely is good to check files for viruses before copying or installing to your machine.
3)Go to Control Panel\System icon\Device manager tab, see if any marked red or yellow,
remove the marked ones and restart computer, let Win95 re-detect the hardware.
4)Try remember when those errors started, if you think its something you did or installed.
5)Be sure you have over 100mb free hardisk space, if free space is small defrag daily, normally I leave about 350mb free hardisk space, recommend 250mb and up, the more hard disk space the better it runs.
6)Check your C:\Windows\Temp be sure its empty, so is the recycle Ben
specially before you do defrag.
7)Be sure you haven't selected mouse maximum travel speed, in Control panel\Mouse.
8)Uninstall your video driver and restart computer and reinstall it, try lower resolution or different driver if applicable.
9) Don't use any 16bit(win3x) hardware software such as mouse, soundcard, etc, I don’t even run any 16 bit software all together in Win95, using 16bit software degrades Win95 considerably.
10)For testing purposes, rename your autoexec.bat and config.sys.
11)Remove all from the startup folder c:\windows\start menu\programs\startup,
also remove all after Load= and Run= from the Win.ini.
start computer & click ctrl+alt+del and see what’s running other than the Explorer, end task all except the explorer and see if the problem still there.
also in the registry, remove all except Systray if present.
HKEY_LOCAL_MACHINE\SOFTWAR
12)Go To Control Panel\System Icon\Performance tab, be sure it says
"Your System is configured for optimal performance" also says "File System and Virtual memory are 32bit", if you don't that means you missed item2 and item10 in this text.
13)If non helped, reinstall win95 from the command prompt using
setup /p f command, that will clean your system files and replace missing and damaged files.
14) Windows 95 Service pack could create errors,
avoid installing it, but you can install parts of it,
such as OLEUPD.EXE, Kernel32upd.exe, Exchange update.
Also Power toys maybe convenient but its not healthy for Win95 to have it.
15)Remove screen savers, Wallpaper, Sound themes entering and exitind
Win95.
16)Open start\programs\MS_DOS Prompt and type mem /c/p, if you have over
575 kb of Conventional memory then you are OK, best to be over 600kb.
17)Go to Control Panel\ System Icon, in the first tab be sure your RAM
is recognized.
