Page Fault on Games

System running Windows 98, 166MHz, 96MB RAM, 10GB hard drive with approx 5GB free space.
Whenever I start a game like Solitaire, Freecell, Taipei, I get the following:

Explorer has caused an invalid page fault in module KRNL386.EXE at 0002:00007a1c.

the address is always the same. the error usually appears at the same time the game setup appears.

The game will play, but most of the icons disappear from SYSTRAY.

I have replaced both EXPLORER & KRNL386.EXE, but the problem persists.

Video card was changed from ATI RAGEII 4MB to S3 Virge DX card with 8MB memory – no change.

Games like Hover and Fury3 are not affected, neither is the Spider Solitaire supplied with Windows ME.

Any suggestion?
