Hi all, The worst thing has happened! I got up this morning, went to turn on my QuickSilver (with a clean build of Jag from last night)and it wont power up! When you press in the power button the light comes on but the machine does not make any noises (PSU fan, HDD spinning up etc), then when u releasse the power button the light just goes off and all stays silent. I have applecare and will be giving them a call, but I just wondered if any of you guys had any idea what might be at fault here? Many thanks.
