Acer's can be prone to retaining a static charge in the ram.

Try removing the ram, then refitting the same ram.

A build up of fluff on the fan, and blocked vents can also
cause the laptop not to start.

Try to power on, and press F2 to see if the laptop will boot to
the motherboard screen.

In the boot menu of the motherboard see if the hard drive is listed
it could just be a broken hard drive.
