Windows 95 problem

I have an old fujitsu machine, 200 processor & 2G Hard disk, which is giving me problems. It was networked but i have changed it to a standalone for home use.

I was getting various .dll errors & hard disk problems so i used fdisk to reformat the disk, however, it still gave problems after i re-installed win 95.

I put in a different hard disk which had been working ok but now when i boot the machine it constantly reboots itself. It never gets past the initial boot.

Any ideas what the problem might be?

Thanks (in anticipation)
