===== NOTES =====

June 2010 - The computer randomly freezes up.  In these times, the light on the front of the CDROM is light up constantly.  The only way to recover is by cutting power to the machine and reboot.  The CDROM was disabled in the BIOS to try and prevent this from happening again.  Installation of a new motherboard has been discussed.

Aug 2010 - The computer has not froze up since the disabling of the CDROM in the BIOS.  However, a motherboard, CPU, and memory has been ordered and is anticipated to be installed this month.

Aug 2010 - Replace placed the motherboard on the computer due to freezing up issue previously described.  In doing so, the CPU and RAM had to be upgraded to match the specs on the new motherboard.  This computer now has much of the governing hardware replaced and should be allowed to be upgraded in OS and software from this point forward.
