No, it doesn't mean you have to get a new hard drive.
Run driver verifier to see if any drivers are causing trouble.
I can't analyse anything until the 29th, that is the day I come home, but I don't know when I am home so you may expect an analyse the 30th.

Please make a backup of your important files and get your rescue media or create one.
Please create a restore point.

Please follow this tutorial to run driver verifier.

Driver verifier stresses your drivers and will crash your pc if any driver fails due to a violation.

Driver verifier should be performed for a max of 48 hours, or when you have a bluescreen, whatever comes first.

If driver verifier has found a violation and you can't get back into windows normally, try to boot into safe mode and reset in safe mode driver verifier, or in the troubleshooting options open command prompt and type verifier /reset.

Note   Note
Your system will act very sluggishly while driver verifier is enabled, this is normal as your drivers will be being subjected to heavy testing in order to make them crash.
