      HELP!!!!!!

      Everything started out fine, I purchased an original 2000HD, (with 2090a
disk controller), about 1.5 years ago, and all was well except I wanted more
memory.  About six months later I purchased an 8-UP dip with 0k board and
stuffed it with 4meg of 80ns 1meg x 1 dips.  All was fine for about 3 months
until one day Ami just froze with out a GURU, when I did the 3 finger reboot
all that happened was the screen went dark red.  After reseating the board all
seemed fine, then a few days later the same happened, the same cure the
frequency of occurance increased to a point where it would not even finish a
bootup.  Out of frustration I removed a bank of memory and all was fine for
awhile the history repeated itself.  The most frustrating part is that while
the system was running and I was able to run the memory test software it
claimed all was fine. I have been operating for about 2 months now without the
memory board installed and not even a glitch.  The lock-ups have all been
random no repeatable sequences can cause an occurance.  

	Whats going on, is it a power supply problem, a board problem or just
the moon out of phase? Please respond
