Macbook Pro freezes when disconnected from Internet

Question

I'm so frustrated, I was doing important work and now I'm about to pull my hair out, I need to finish what I was doing but I can't even turn on my computer without it freezing, I literally can't even move the mouse because it freezes right on loading screen every time I restart, here's the story.
I disconnected the Internet for just a few seconds, then the computer froze. So naturally I restarted the computer, but each time I restart, it just freezes, I can't move the mouse, I can't click on anything, it's just frozen. Let me know how frustrating that is that you don't have computer access after working on important files.
I have a 2008 non unibody Macbook pro with OS X mavericks, I knew the computer froze when I turned off wifi, but I correlated that with the app that I was running, since I wasn't running the app this time, I thought I could turn off wifi no problem.
But like I said, now I can't even restart or use it at all. I can't even use safe mode because it freezes there too. I can do the cmd+shift+ctrl+r thing and I can connect to the Internet that way, but there's nothing I can do from there. Once I restart, the Internet connection is still disconnected in the main operating system.

Answer 1

Okay I solved the problem. For anyone who runs across this issue in the future, here is the solution:
Step 1) Turn on the computer and hold CMD + Option + S, this will boot the computer into single user mode
Step 2) Type in "Mount -uw /"
Step 3) Type in "vi /Library/Preferences/SystemConfiguration/preferences.plist"
Step 4) Scroll down until you find this part:
<key>Interface</key>
<dict>
        <key>en1</key>
        <dict>
                <key>AirPort</key>
                <dict>
                        <key>JoinModeFallback</key>
                        <array>
                                <string>DoNothing</string>
                        </array>
                       <key>PowerEnabled</key>
                        <false/>
                        <key>RememberJoinedNetworks</key>
                        <true/>
                        <key>RequireAdminIBSS</key>
                        <false/>
                        <key>RequireAdminNetworkChange</key>
                        <false/>
                        <key>RequireAdminPowerToggle</key>
                        <false/>
                </dict>
        </dict>
</dict>
Step 5: Edit the part where it says:
<key>PowerEnabled</key>
<false/>
and change it to <true/>
Step 6: Hit Ctrl + X, hit Y for Yes, press enter.
Step 7: RESTART AND YOU HAVE YOUR COMPUTER BACK!!
I panicked by the way because as someone said earlier, it's nearly impossible to fix:
You cannot fix this problem with Safe Boot, Repair Permissions, Repair Disk, re-install Mavericks, restore from Time Machine backup, reset the SMC, reset PRAM, or boot into single-user mode.  Thus far, the only solution is to boot from a (homemade) Install OS X Mavericks USB, erase the hard drive, perform a clean Mavericks install, re-install your applications, and manually restore your data.
Anyway I'm thankful for Ira Wolf 81 for figuring out, he deserves all the credit for this, I merely repeated his steps and found out he was right. Cheers.
