I bought an Emachine T2542 at a Turkey Day door buster 3 plus years ago. It worked fine until last week when it decided not to boot any more. I removed the side panel to peek inside while trying (again) to boot up. The CPU cooling fan was not spinning. I took it to a local "Mom and Pop" repair shop for evaluation. They verified my earlier finding then hooked the fan power (three pin) plug to another computer and the fan worked fine so they told me the Mobo was dead. I bought an Intel D845PEMLY Socket 478 mobo (Geeks.com) and installed it only to find the fan still doesn't work. Anyone have an idea what is going on? Thanks in advance for your help.
