Guys I am having a problem with my MBP. One of the safari tabs was unresponsive this morning and I forced close safari to restart the laptop.

After I shut down the laptop, I no longer can turn it on. The progress bar just won’t finish loading after I enter the password. Repaired the disk permissions and reset PRAM but it didn’t work. Can’t even enter safe mode.

Did anybody here encounter the same problem before? I’m trying to see if I can get this fixed without sending it to authorized reseller or third-party expert. There are many important documents in my laptop and I don’t think that I have a backup of every of the documents.

Thank you in advance.
