This M$ Article may be of some help

by OH Smeg Moderator In reply to Windows 95 Blue Screen?

Though why you set a User Name & Password on the initial install is slightly beyond my understanding.

But then again it's been a very long time since I have worked with 95.

Not many know the trick that if you just leave the password box empty and type a name in the top (preferably your own) it will never ask you to login again.

Before you did a reinstall, did you do a full format of your drive?

by Peconet Tietokoneet In reply to Windows 95 Blue Screen?

Hopefully you did a backup of your drive.
Do a full format of your harddrive before you do the reinstall, if you do not do this then the data from the OLD Windows system files conflics with the NEW Windows System files, hence the blue screen of death.

How to Format a Computer with Windows 95, 98, or ME.
Warning - Formatting hard drive information does not permanently erase the data. Even after a computer has been formatted, deleted files can be easily recovered. If you want to permanently wipe your hard drive by completely overwritting hard drive data.

When using the format command, remember all information on the drive you wish to format will be completely erased.


1. Start the computer in DOS. To bypass Windows, press and hold the F8 key after the computer displays the system settings. The C prompt should appear.

2. Label a blank, formatted floppy disk and insert it into the floppy drive.

3. At the DOS prompt, type: FORMAT A: /S. The /S option prompts the computer to copy system files to the floppy disk. The computer will format the disk and copy system files to the disk.

4. Type "No" to end the format command. The startup disk is ready for use.

format a:
Would erase all the contents off a disk. Commonly used on a diskette that has not been formatted or on a diskette you wish to erase.

format a: /q
Quickly erases all the contents of a floppy diskette. Commonly used to quickly erase all information on the diskette.

format c:
This would erase the contents of your C: hard disk drive. In other words, unless you wish to erase all your computer's information, this command should not be done unless you're planning to start over.

The below steps are for users with MS-DOS 5.0+, Windows 3.x, Windows 95, Windows 98, Windows ME, and Windows NT 4.0.

Place the bootable diskette or disc inside the computer and reboot to get to the DOS prompt. In some cases you may need to boot the computer with CD-ROM support or press a key to boot from the disk.
At the MS-DOS prompt type format c: /s
The computer will ask you "Are you sure you want to erase everything on drive c:" if you are ok with doing this press "Y" for yes and press enter.
After doing this, the computer will begin the formatting process. While the computer is formatting make sure no errors are encountered.
Once the format process is completed successfully, at the MS-DOS prompt type fdisk /mbr and press enter. This should return you back to the MS-DOS prompt with no message. This step is not required but recommended.
Once back at the MS-DOS prompt, reboot the computer with the boot disk still in the computer.
Once back at the MS-DOS prompt, insert either the diskettes for MS-DOS, Windows 3.x, Windows 95, or the CD for Windows 95, Windows 98 or Windows NT.

Windows 95 CD users

Place the CD into the computer.
Type X: (where x is the CD-ROM drive, generally this is D).
Once at the appropriate drive, type CD WIN95 and press enter to get into the Windows 95 directory.
Once at X:\WIN95> type "setup" to begin the installation
Follow the on-screen instructions to complete the installation.

If you are encountering issues during the setup process, you can add additional switches to the setup command line. These switches can be found on the Windows 95 Setup Switches page.

Is it able to boot to safe mode?

by Slayer_ In reply to Windows 95 Blue Screen?

The fact that you can get to the login tells me the processor is working.
After the login is the graphics resources and network drivers, etc. Perhaps one of those has a problem.

Copied Files?

by Tyharo In reply to Windows 95 Blue Screen?

When I installed Windows I used FDISK and formatted the partition I was going to be installing on. When I boot after the blue screen I dont get a choice to go into safe mode.
Would 512mb ram be to much? I got an error saying not enough memory once but I removed 512 an then i didnt get it again.
Since I copied the CD's content onto the main drive in a folder named WIN95 would that be causing the blue screen?

Copied Windows 95 install files on the hard drive are not a problem. At least not in a folder like Win95 which is not a folder that Windows creates.

The 512 MB of RAM could well be the problem. Windows 95, 98 and Me were all finicky if you had more than 511 MB of RAM. Some installs worked fine with 512, others locked up with a blue screen.

It could also be that the default Windows 95 drivers just don't like hardware on the motherboard.

I would start by dropping down to 256 MB of RAM and see if that helps.

For Safe Mode, press F8 just as soon as Windows starts loading after POST.

Now disable devices in device manager, 1 at a time, until you find the crashing culprit.

Troubleshooting Fatal Exception Errors

by Peconet Tietokoneet In reply to Windows 95 Blue Screen?

Clean Boot Your Computer
Because there are many conditions that can cause a fatal exception error, the first step in resolving the issue is to narrow the focus. To narrow the focus, try a "clean boot" of your computer.

Clean-boot troubleshooting refers to methods of reducing problems that may occur because of your computer's environment. Many problems occur because of conflicting drivers, terminate-and-stay-resident programs (TSRs), and other settings that are loaded when your computer starts. For additional information about how to clean-boot your computer, click the following article numbers to view the articles in the Microsoft Knowledge Base:

How to perform a clean boot in Windows 95
The following steps can help you to determine if the problem that you are experiencing is due to the real-mode configuration of your computer. This could include drivers that are loaded from your Config.sys and Autoexec.bat files.

Restart your computer. When the Starting Windows 95 dialog box is displayed, press F8, and then choose Step-By-Step Confirmation from the Startup menu.
When you are prompted, load the following items (if you are prompted to load any other items, press N):
Dblspace driver.
Load the Windows 95 graphical user interface (GUI), choosing to load all Windows drivers.

NOTE: Windows 95 does not require the Config.sys and Autoexec.bat files, but some tools installed on the computer may require them. You should never rename the Config.sys and Autoexec.bat files until you perform a successful interactive boot to verify that they are not needed.

If the clean boot of your real-mode configuration eliminates the issue, isolate the conflict with a terminate-and-stay-resident (TSR) or real-mode device driver using the Step-By-Step Confirmation function.

Load Windows 95 by booting to a command prompt and starting Windows 95 by typing win, holding down the SHIFT key for the duration of the boot. This prevents any programs from loading automatically at startup.

If the issue is resolved by preventing programs from loading at startup, investigate the following possible sources.
The Winstart.bat File
The Winstart.bat file is used to load TSRs that are required for Windows-based programs and are not needed in MS-DOS sessions.

For additional information the Winstart.bat file, click the article number below to view the article in the Microsoft Knowledge Base:
Some TSRs Moved from Autoexec.bat to Winstart.bat During Setup
The Startup Group
If the issue is resolved by bypassing the Startup group, remove each of the programs from the Startup group individually to isolate the program that is causing the problem.

The Run Key in the Registry
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
How to back up and restore the registry in Windows:

You can prevent programs from loading by removing the program's string from the following registry keys:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\ RunServicesOnce
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\ RunOnce\Setup
Programs may also be loading from the following registry key:

The Win.ini File
The "load=" and "run=" lines in the [Windows] section of the file can start programs automatically. See the following section for more information.

Test Windows Configuration Files
To test the Windows configuration files, use the following steps:

Boot to a command prompt.
Rename the Win.ini file by typing the following command:
ren c:\windows\win.ini *.bak
Start Windows 95 by typing win. If this procedure corrects the problem, ensure that the "load=" and "run=" lines in the [Windows] section of the Win.ini file are either blank or preceded with a semicolon ( to prevent the items from loading.
Rename the System.ini file by typing the following command:
ren c:\windows\system.ini *.bak
Windows 95 requires a System.ini file to load the GUI. Replace the original file by typing the following command:
copy c:\windows\system.cb c:\windows\system.ini
NOTE: Starting Windows 95 with the System.cb file does not load a driver for the mouse. Edit the new System.ini file, adding the following lines:
mouse=*vmouse, msmouse.vxd

Start Windows 95 by typing win at the command prompt. If replacing the original System.ini file with the System.cb file corrects the issue, the problem most likely resides with either the [boot] or [386Enh] sections of the original System.ini file. Restore the original file to troubleshoot it.
To isolate the cause of the problem, place a semicolon ( at the beginning of a line to prevent the item from loading.

It occurs to me, you would have better luck with Win98

by Slayer_ In reply to Windows 95 Blue Screen?

I ran Win98 on a 2.6 ghz processor and 512mb of RAM, ran like a champ (except for the Win98 epic failures, but during the 30 seconds a day it wasn't crashing or erroring or freezing, it ran great)
