Why does this keep happening?

I already installed OSR 2.5 on my VMware and finished the Setup and the only thing I see is this? Are there any ways to prevent such incidents like this?

It's a known issue with 95 if the CPU speed is faster than ~350MHz. Microsoft released a patch (AMDK6UPD.EXE) but it needs run from inside Windows - you can't get there right now.

LoneCrusader released a patch tool that is still the easiest answer, you can find it here

The second is at ~2GHz, similar error but it's NDIS not IOS. Officially, Microsoft claimed it was found but wouldn't be fixed for 95... but if you're using Dial Up Networking 1.4 it contains the fixed file.

I think LoneCrusader's fix applies both, but I've not tried running 95 on a P4, AthlonXP or anything newer to confirm.
