Invalid page fault is caused by a problem moving data between physical memory and the swap file - either a reference to a page in virtual memory that isn't currently valid, an error reading from the swap file, or something similar. If this is Win9x, badly fragmented swap files can cause this to happen and in fact, fragmentation of some drivers and .DLL files as well. The first thing I'd try is to defragment the drive.

Does it bomb out in the same place every time when it crashes? You seem to imply that from what you've said above.
