m trying to run PBA bowling 2 and PBA 2001 for Windows. At first I thought it was an operating system issue so I partitioned my hard drive and installed XP on it. I was still encountering the same graphical glitches that I did running Windows 7. I even tried a different video card but there is no change. I know about DOS box and since this is an early XP game I even tried virtual XP first but that did not help either.

Are these games just incompatible the newer architecture and not just the operating system

You could try running the games under Linux via WINE and see what happens. That might work when real Windows doesn't, especially for older games.
