Windows 95 does not start due to system files that are corrupt.
Cause:
The system files which were copied onto the root drive when Windows was installed are corrupt.
Solution:
Start Windows using the Startup diskette.
1) Insert the Windows 95 Startup diskette into the startup drive.
2) Reboot the computer.
3) To change to the startup drive, type the following, and press ENTER:
<drive>:
(where <drive> is the letter of the drive containing the Startup diskette).
4) Type the following command at the prompt, and press ENTER.
SYS <drive>:
(where '<drive>' is the root drive, which is typically C:).
NOTE: The system files contained on the Startup diskette are copied onto the root drive.
5) After the message 'System transferred' appears, remove the Startup diskette from the drive.
6) Reboot the computer.
