model number of your motherboard without opening the case? If I open the case, it will invalidate my warrantee. I have looked at the specs for my machine of the emachines website, but they don't tell me what I need to know. Perhaps I am being thick.I need to know the mobo manufacturer and model number, if there is one, because of a driver issue. The drivers provided on the website are not going to help me, because they are for vista systems. I removed vista and installed xp. my machine is an emachine, model t3612.
