Yes, it may sound weird, but how can I find out which one? I'm not extactly an expert when it comes to PCs.Thanks,Greg

Generally, you need to take the cover off your PC and search for MOBO manufacturers' data on the board itself. Hopefully, they put it on the top side of the board.If you have a packaged unit, i.e., Dell, HP, etc., you could try searching their website for information but they usually don't have it stated that way. One way is to look for BIOS updates, which may give you a clue to the manufacturer.

Thanks. That should work.Greg
