Works only with 1 ram slot used

[mmellish]

My computer will shut off when I print if I have both of the ram slots filled? It will work fine with just 1 ram. Why? Any help would be appreciated

incompatible ram
incompatible ram with motherboard
bad memory slot
bad ram stick

these are your possibilities.

test bad ram with memtest 86+ booted from a floppy or cd rom
