Starts making a clicking sound..then wont boot up.

Well, It sounds like there is something lodged in your Hardware drive...The beeping is probably a warning signal to tell you that it is not properly booting up...You should go to a Computer Repairman...

Only a guess sounds like hard drive is malfunctioning, hope you backed up your important bits

A clicking noise usually indicates a bad hard drive. Any eMachine is now very old (in computer years), with an obsolete operating system.

You should consider replacing rather than repairing.

If you can hear a click (quite loud) from the engine compartment, but the starter won't crank, this also could be caused by discharged battery-----------------------------------------------------------------------------

sounds like you need a starter

Try starting the machine from the hard drive normally. Put the CD in the drive. Wait until the machine starts up completely. Then,

1. Click the Apple menu (top, right corner of the screen).
2. Click "System Preferences"
3. Click "Startup Disk"
4. Click the CD icon.
5. Click the Restart button in that window. Your Mac will ask you if you are sure you want to restart. Click Restart. It should boot from your CD

Good luck! Please let us know if this helps you solve the problem.

buy a boot disk or if you made recovery disks use them and when it starts up go to boot manager and click boot off disk

it means that ur hard drive is dead send it back to the company

try these two alternatives:
1.try to clean or change the slot of the memory
2. check on th power supply you put on your motherboard for the new board there are the socket for the power to be placed on the otherboard
