The most effective way is to buy a new memory chip and see if it
disappears. If it does, put the old chip in the unused slot and see if
it comes back. If not, you've doubled your memory, no big problem. If
the error remains with the other chip, it's time for another CPU and
motherboard. You can get all this for under $200. Fixing hardware
problems with computers is a matter of replacing each pieces one by one
until you isolate the problem. You probably can't fix it, whatever it
is, so you just have to replace it. It helps to have a supply of spare
parts on hand from previous projects. Even an old something can prove
everything else works.
Memory is a pain because there's so many subtle incompatibilities
between the speed/type of memory and the motherboard's capacity. So you
have to take the existing memory chip or motherboard manual to the shop,
to make sure you get the identical kind. Look for places with a
lifetime warranty on memory; that way, in a predicament like your
current one, you can get it replaced for free. Memory is like forty
bucks for 512 MB, so it's no big deal anymore. Unless you have some
ultra-old type that isn't made anymore. In that case you could go
through the bins of $1 used memory at a PC recycling shop (RE-PC, etc),
but with the subtle incompatibilities, it's much easier to just get a
new motherboard and memory.
