    On some Acer Aspire models, you may need to remove the battery before and after replacing the ram. Hopefully it's not a board issue, but I'd go with something back's suggestion on the ram, but remove the battery first if you can and make sure it's unplugged. There's been one model that I had to let the battery drain out the CMOS settings just to get the ram to be recognized correctly, so you might have to do that too in some cases, but not all of them.
