hi all this is my first post ! i have a aa1 zg5, which used to work fine now when i switch it on, it will not boot, if i press f2 for bios or f12 for boot dev options, it just sits there doing nothing, it will not boot or let me into the bios i have tried the emergency usb bios flash, and nothing ! im guessing a hardware problem, has anyone any ideas, as it's a good machine and i dont wanna sell it for spares ! thanks in advance jody
