We have just returned from 2 weeks holiday and cannot get our PC to start up. It is an Emachines 610 and the power was off the whole time we were away. Now we have tried to boot it up and ... nothing! There must be power getting to it somewhere/somehow because the light indicator for the ethernet cable lights up and stays on. I have tried a different power cable to no avail, there is just nothing happening when I press the on button, no lights or sounds. Any ideas? Thanks
