I've got a blown motherboard on an emachine T4170. Turn it on power supply comes up and that is it. I read in one of the post that I will have a better chance of maintaining my ability to load from the recover disk, including the OS, if I replace it with a compatible replacement motherboard. Where can I find out which motherboards are "compatible replacements". I want to get some pricing to determine if it is worth it to do this repair.
