Some thoughts you might try.
Minimum install; just video card, ram, hd, and floppy. Add other cards after you are up and running.
Test your ram with a memory tester such as this one http://simmtester.com./
Prior to installing enter the bios and load fail safe defaults. See if there is a bios update that addresses any install problems.
Have you tried coping the i386 folder to your hd and install from there? If you do this, you will need smartdrv.exe either on the hd or floppy.
