I'm running Windows 95 on a Intel Pentium MMX 233. Few weeks ago I installed FreePascal on my HD. I couldn't run most of it's tools because I was getting Page Fault errors. I reinstalled my Windows and it's still the same. Now I see that a game I'm playing on that computer for 5 years is getting the same error. Now when I think of it I remember that my toshiba laptop running on Windows 98 has stopted executing all dos4gw programs (what ends with General Protection Fault) even if they worked before.
Do you have any idea what may cause that problem (except that all M$ products sucks) ?
