I have a problem with an Aerco mem upgrade I recently purchased. It worked for about a month and then suddenly stopped. My computer would no longer boot with the upgrede attached. If I hook the board up and then remove a single memory chip (any one will do) my computer will boot, but of coarse it only sees 500k of mem. This is also the case if I disconect either of the two ribbon cables from the board. The memory is good, I checked it out. The other thing I noticed was an awful lot of noise on the +5 and ground lines of the board. This noise is not present on the ST mother board. I changed all the caps and got a little improvement. If anyone has seen this problem or can suggest some things I could still check, please tell me. Thanks, Randy Hosler
