Help is needed. My emachine (5Years old) with Windows SP was running (with husband working on it). The machine shut itself down (screen went dark) and powered itself off. All went dark and we have not been able to turn it on since. We have checked all of the connections and they seem fine. We took it to a computer store and they said that the hard drive was BLANK. That this may be caused by Heat or Static. I have searched on-line but can fine nothing to verify this Heat or Static statment. I really would like to fix this machine but am at a loss so any guidance would help.
