The usual problem with these emachines ( and Advent and Medion computers too )is a motherboard fault in the processor socket which effectively stops it boot, i.e. no signal. the board needs replacing but normally the power blows too as aresult of the motherboard problem. This happens as a result of the power plug beside the processor with 2 yellow and 2 black cables on spooks the psu when the cpu socket blows.
Easy answer replace the board, restore windows, time approx 1:30 minutes and cost around £80.00. need FREE help ? chrisf989 07926106150
