Do you know what type of motherboard it is? Generally if you know the
manufacturer, you can find out what the codes are from google. They tend
to be the same for all motherboards made by a particular manufacturer.
My experience is it is usually either memory or video. Are you using
on-board video, or do you have a video card? Is it a video card you
could try in a different slot? Have you tried the memory in other slots?
Hope this helps,
