My MacBook won't turn on!!!

A few ways of doing this

1) restart mac and press down the trackpad button after you hear the startup noise

2) if that does not work try opening up disk utility which is located in applications and then in the utilities folder and click on the icon of your disk under the left hand column then go up to eject button and click eject

3) or open up terminal found in the utilities folder within your applications folder and then type in drutil tray eject and then press return

4) Finally what to do is try pick up your macbook tilt the macbook to the one side and press the eject key and hopefully the effect of gravity will allow the CD to fall out.
However, I would say that DVD drives in all macs are a bit suspect and if your macbook is still under warranty or under AppleCare take it back to the Apple Store and tell them that the DVD drive is faulty and they should replace it free off charge. Hope this helps.

Try quitting some unused applications > Apple Menu> Force Quit > select open applications > and quit.
Another way is to restart the Macbook. Make sure you uncheck "Reopen windows when log back in"

If under warranty get it replaced.

Jacob I usually find using a free application called soundsource available at http://www.macupdate.com/app/mac/11334/soundsource gives you all the available options for input and output options. Once downloaded instal it into your applications folder and open it up, it will appear in your menu bar as a headphone icon. Click on the icon and you will see what options you have. Hope this helps.

Hi, Did you try restarting your computer? It may be that something is blocking the application such as firewall or anti-virus. etc... If you are computer savy look in to firewall settings. Then restart and try webcam again. Good luck.

Your hard drive might be failing.
If you have the original install discs that came with your computer, insert disc 1 into your computer. Then turn off your computer and then turn it back on again while holding down the Option (alt) key and double click on the CD icon that pops up. Then when the computer boots from the DVD, click on Utilities and the open up the Disk Utility application. Run "Repair Disk" with your internal hard-drive selected. If this program cannot fix your problem, you may need to invest in purchasing a new hard drive and replacing the one in your computer.

I would start by attempting too restart. If this does not fix it, open Disk Utility (Applications -> Utilities -> Disk Utility). From here click verify permissions and then verify disk. If either of those come up with errors, then click the corresponding solution (repair permissions or repair disk). This should solve any problems you are having, but if it does not, Insert the USB drive that your MacBook Air came with and reinstall the OS. Good Luck!

Your OS may need to be restored. Do you still have your original install CD? There are detailed instructions on how to do the restore online. Here is an Macbook Repair Guide that shows how to open a Macbook. If you want somebody else to do it for you go to Macbook Repair.

Hard Drive or MAMORY disfuntioning. firstly try Removing and replacing the hard drive (to make sure it connects properly) before tampering with the memory. Could be that the hadr drive has bad sectors and cannot read the system files...

Hi,

Apparently, you computer has some unexpected software running during the startup. In order to get ride of these software, you could check your register table manualy by regedit or download this software, which will help you to find if there are any suspect software running at the startup.
