Thanks!1. Restart your mac and hold Command+R until it boots in recovery mode
2. Click Dish Utility
3. Click your Macintosh HD and choose Erase in the upper menu and then choose Mac OS Journaled and then Erase to the right. This basically formats your HDD
4. Quit Disc Utility
5. Click Reinstall OS X (make sure that it has the Mavericks logo)

Do this.Is it my internet problem or I erased some default file in my MacBook? (My PC run very smooth) though
Thank you very much for replying, trying to reinstall now.Do this.
Hold command-option-r while booting and this will get you into Internet Recovery.
Start Disk Utility and select the disk brand name at the very top (like Seagate 500GB or whatever) and erase the entire disk as Mac OS Extended.
Now quit Disk Utility and click reinstall OS. This will download the entire OS from Apple's servers and give you the same OS version that came with the machine.
Just leave the lid open and let it run, it won't go to sleep while updating like this.Thank you very much for replying, trying to reinstall now.
