My Acer Aspire does not come on, when i turn it on it only shows the blue light on the button but the screen remain black, after some research i have come to know it as a blackscreen of death. And got some i dea on using a usb disk and dowloading the bios files but still it does not work, the only thing it does is a blue led blinking in front of the keyboard.

Can any one help on how to solve the problem please!!
