Answer to: Why my acer aspire 4738z 2008 not workingTHE IT GUY The problem your experiencing could be down to faulty motherboard, RAM and or removable devices such as USB, RAID and HDD Bays etc. Try removing the battery, disconnecting any external devices and removing the RAM and hard drive and press the power button. Do you get any beeps? Does anything happen? Replace the RAM with known working RAM and then try again.
