Machine Check Error Occurs on Windows Server 2003 on Multiprocessor Machine

Recently, I encountered a machine check error on a AMD motherboard running 2 x dual-core processors making it 4 CPUs and 16 GB RAM. Operating system running is Windows Server 2003 R2 SP 1. The machine is very powerful and performance issue is definitely out of the question. Software causing the machine check error is a .NET application compiled in x64 configuration platform.

A trial and error concludes that x64 could be causing some problems to the set of codes I wrote. BTW, the .NET application is just a small application doing duplex serial communication via RS-232 serial ports. A change from x64 to x86 compilation seems to work miraculously. After further searching on the internet, I attempted to install the latest Service Pack. The problem seems to have gone away even with a x64 compilation.
