Chances are that there is Insufficient Power to the Computer. Use a Voltmeter and Confirm that there is Adequate ac Voltage at the Wall Outlet. Check the ac Cord next-it Might be Loose or Disconnected. See that the Power Switch is Turned on and Connected Properly. Check the Power-Supply Fuse(S). The Main Fuse Might have Opened. Replace any Failed Fuse.
If You Replace the Main Fuse and the Fuse Continues to Fail, You Might have a Serious Fault in the Power supply. Try Replacing the Power Supply.
