Stuck in a loop just saying "Repairing Disk errors. This might take over and hour to complete"

Hello, as stated in the subject I am having an issue with my HP ProBook4440s with the loop of just saying "Repairing Disk errors. This might take over and hour to complete" I have done a System Diagnostics and both a memory test and a Hard Disk Check and my PC has passed both, so what I would like to know is there anything else I could do or is it possible to turn back the PC to the last point where it was working without loosing any data or some other way to fix this without loosing any data? Should I take it to a repair shop? I really need this PC for school and I have a lot of important files on it that I would like to keep. 
I would love to hear any advice or help : ).

Unfortunately, in all honesty, the answer to all your questions about doing some kind of rollback without losing data is NO.

There really is no way to do that without having existing data backups, and despite the name, System Restore does not backup user data, so that is of no help.

If this were mine, my immediate priority would be recovering data from the drive ...

Your best bet for recovering data now is to do the following:
1) Remove the hard drive from the old PC
2) Purchase a USB-to-Hard Driver adapter kit (like the one illustrated below)

3) Connect the old drive to a working PC using that adapter
4) Try to retrieve the files and folders you want to save from the old drive and copy them to the new PC.

If this does not work, then you need to do the following:
1) Download and install this utility on a working PC http://www.majorgeeks.com/news/story/recover_data_in_3_steps_with_minitool_power_data_recovery_free_...
2) Run the data recovery utility to see what can be retrieved from the old drive.

If that tool does not find what you need, an alternative is Recuva http://www.piriform.com/recuva

And, if that does not work well, the best tool out there is this one, but only the trial version is free http://www.file-recovery.com/
