I have another post in which I mentioned that we went on a short vacation and unplugged the computer. Upon our return, we plugged in the computer and pressed the power button and nothing happened. No fans, beeps nothing. Just a green light on the MOBO. Swapped out the PSU, and CPU fan, replaced the CMOS batt, reseated RAM and checked the power switch for operation. After working with EMachines for awhile they said it was probably the MOBO. Recommended I take it to Best Buy (Geek Squad). After spending $56. for them to diagnose the problem, they said"Yup, looks like the MOBO!". This is my wife's computer and I thought she was backing everything up, especially Quicken, since that's where she does all her finances. I tried to read her backup CD in my comuter and it was blank. So, I need to know how to swap out the MOBO without losing her data. Can't backup with bad MOBO.
