need serious help. laptop isnt working.

[The Radiated Banana]

My mac is stuck on startup screen. The spinning gear wont stop. This happened directly after i tried to reboot my computer after installing and running avg.

 

 

When I try booting in safe mode, the progress bar shows up, once the bar fills, its just a spinning gear again

 

 

Ive tried repairing disk, nothing changed afterwards.

 

 

Ive tried restarting nram or something ny holding cmd+option+p+r. Didnt work afterwards.

 

 

Ive tried reinstalling the OSX but i cant. The store i used previously is different from the country i am in now.

Sounds like what happened to my macbook pro.  It was like that for a few days and eventually wouldn't even turn out.  I still miss it

 

I knew better than to take it outside in the sun, it wasn't worth a fried laptop

(If you haven't tried yet)

try this its a step by step to try and fix it 

 

Take each of these steps that you haven't already tried. Stop when the problem is resolved.

   

Step 1

    

The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.

   

There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.

    

a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.â€

b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.

c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

Step 2

Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.

If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.

Step 3

 

Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.

  

Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.

   

The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

   

When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.

 

If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)

 

If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.

 

Step 4

 

Sometimes a boot failure can be resolved by resetting the NVRAM.

 

Step 5

 

Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.

 

This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.

 

Step 6

 

Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.

 

Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.

 

Step 7

 

Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.

  

Step 8

  

A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.

  

Step 9

  

If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

My mac does this all the time when it wants to update.

 

I just open it up, take the hd, battery and ram out.

 

Then I proceed to put it in the freezer for about 7-8 min

 

Try that,
