OK so I put together every and loaded 32 bit Vista. Everything seemed to be running fine until I started play Lord of the Rings Online. About 20 minutes into playing I got the blue screen of death that stated "Memory Management". I doubled check and the system is reading all my memory (actually it's reading 3.5 of 4gb but that is because I'm running a 32 bit OS)
Also after I restarted I get an error that states run32dll has halted.
Do this, go to Start, right click My Computer, Properties, Advanced Tab, Start-up and recovery, settings and under system failure uncheck Automaticly restart = false/uncheck. The next time you get a blue screen you'll have enough time to jot down the problem error.
