I have a emachines 810 it's a few years old now and it will not power up. When I turn on the power it will automatically come on without pressing the power button on the machine. The orange light and green lights flashes and the fans are going but nothing else happens the cd rom will not open and nothing appears on the monitor. Any help would be great! My warranty ended 5 days ago so I'm not sure if I should renew my warranty for £70 and get it fixed or is it a small job that could be done on the cheap in the local pc shop.
