what are the considerations i should take when buying a new motherboard?
It sounds like you want to use the components you already have on a new mobo, please correct me if I am wrong. Since you didn't post your specs, I am working in the dark but will do the best I can.
If your current mobo carries a max of 4 gigs RAM, you have an oldie. IF this is true, manufacturers are not making new boards for the technology you have. The main problem you are going to run into immediately is finding a new board that will accept your current, old technology but allow you to use more RAM. Probably you will have to turn to Ebay, and the odds are not good that you will find what you are looking for. If you do happen to find a board that will accept your current RAM, HDD and CPU, they will probably be asking almost as much as a new mobo would cost, and no guarantee how long that old, used board you purchase will last. Whatever board you buy, make sure that the CPU socket is the same as the current one on your old board or your CPU will not mount. Same goes for memory, make real sure the "new" board will accept the type of memory you have. If you can locate the same board that will take more RAM than your present one, you will hit the next wall: older RAM is hard to find, and again, you will have to turn to Ebay. You will discover that people who are selling older RAM want as much as new memory costs! They figure they are going to cash in on memory that is hard to find. I have gone down this "upgrade" road with several people and it ends up being expensive enough so that it isn't financially realistic.
