Blue screen on my mac book air - Apple MacBook Laptop Computer Mac Notebook

If you are running 10.7.3 or later hold down the option key while starting up and select the recovery partition to start up. Then select utilities/disk utility and try repairing your hard drive. If this doesn't work you can also reinstall the OS from the recovery partition.

It is not finding the OS. Could be a corrupt OS or bad SSD. Hold down "D" immediately after the dong sound until the hardware test screen shows. Use the arrow keys to pick your language. Follow the instructions and post the error code if one is found. Chris

Hello,

Go to System Preference on your Mac which is a setting icon (Gear) then go to DISPLAYS > ARRANGEMENT >CHECK ON THE MIRROR DISPLAYS.

You can also set the monitor arrangement sideways or upside down.

Hope this helps.

Sounds like the gel has dribbled down into the workings and has effected the circuitry. Time for a new monitor. More importantly, why the heck were you using a liquid/gel sanitiser on electrical equipment. Use dedicated screen wipes

have you tried booting from the install disc?

The DVD ticking sound is normal and happens every time you power on. The blue screen of death is not normal. The flashing question mark means corrupt start up file. Re-install the operating system or insert disc 1 of your gray install disc and go into disk utilities and select repair permissions. Then select repair hard drive.

Insert your installation disk that came with the mac and hold the "c" key while turning it on, this will force it to boot from the cd drive. Choose your language from the selection screen, I'm going to assume English, and choose Utilities --> Disk Utility from the drop-down menu on the top of the screen to open the Application. From there select the Mac partition of your Hard Drive on the left which should be called "Macintosh HD if you did not change it. In the "First Aid" tab, you will see two buttons on the bottom right hand corner of the window, "Verify Disk" and "Repair Disk." First Verify the disk, then Repair it, if it does not work at that point you will likely need to format your Hard Drive. If you do not want to lose any work and can't retrieve it any other way; get an external laptop HD case (specs are 2.5 inch by standard 9 mm, but could hold thicker like the 12 mm Western Digital Blue Caviar line above 500 GB) from Radioshack or similar, it should run you about $25. Transfer or backup any data you want to keep to your desktop, external or similar from there and format the disk and reinstall Mac OS. Cheers.

your disk partition is having problem.if u have not taken backup then boot the system with FW mode with saperate Laptop and backup the data,then repartition the hdd and install freshly
