IMHO, it does sound like a hard disk problem. Starting in safe mode bypasses some software that might reside in bad sectors on the disk. In safe mode, run chkdsk c: /f from a command prompt, or double-click "My Computer", right-click on the C: drive hit Properties/Tools/Check Now. Check the "Scan for and attempt recovery of bad sectors" box and hit start. This will read and correct (remap) any bad sectors. It will also take a long time (up to several hours).

If you can save all of your data files to an external drive, do so. Collect all of the installation media for whatever programs you wish to run, including a copy of Windows 7 Home Premium, replace the hard disk and reinstall everything from scratch. Your main drive is failing and needs to be replaced. I don't think you will be able to simply clone that drive to a new one. You're missing some important files, so a total rebuild is in order. I usually reinstall everything on a yearly basis as a matter of routine. I find that whirlydisks seldom last more than a couple of years of constant use anyway.

Since I have no idea what you have installed on your system, I generally cannot advise you. Most computers come with either DVDs or separate partitions on the hard disk containing the files necessary to restore the machine to factory preset condition. In some cases, the files are in a separate, hidden, partition and can be used to burn recovery disks. You'll need to contact Lenovo to find out how. They may also have some suggestions on how to replace and rebuild the disk. I, personally, would replace the current disk with a much larger one - they're cheap. For a laptop, an SSD of sufficient size to be useful (512GB or larger) would be cost prohibitive. In a desktop setup you can use a small SSD (128 or 256GB) as a boot device, inexpensively.
Any software you have added, such as Microsoft Office or other applications will have to be reinstalled. You need the disks or installation files for those programs. If such programs came with the machine, then a factory restore will automatically install them. Factory restore will also load all necessary drivers.
The following is my own opinion and practice. My research has demonstrated that, if you are running a Microsoft Operating System, you DO NOT need a third-party antivirus program. Windows Security Essentials is available free for Windows 7 and IMHO is very good. Just download it from Microsoft and install it after the OS and Drivers are installed, and Windows has been activated. Microsoft also sends out a malware removal tool each month with the second-Tuesday updates. When you get to Windows 10 (free next month) You will need third-party antivirus even less. DO NOT install AVG, Semantec or anything else. Defender is free, and included in Windows 8 and 10.
Lenovo and many other companies preinstall AVG or Norton or Kaspersky, all of which are paid subscriptions (once the short trial has expired). My advice is to remove all such software. You only need Windows, MSE, and necessary applications. All of this other crap is just that...Crapware. One of the first things I end up doing to a new machine is remove all of the trials and junk software. Computer companies get paid to install that stuff in the hope that the customer will agree to a subscription after the trial ends. Besides, almost all third-party AV systems slow down the machine, sometimes significantly. Microsoft cheats and builds it into the OS. Also note that a factory restore will likewise reinstall all such software.
Finally, after 4 or more years, perhaps it's time to simply replace the machine. There's a lot of good bargains available. Look especially in the Refurbished section of Newegg or Amazon or Tiger Direct. IMHO, refurbs are perfectly good machines that have been through the initial 90-day "Infant Mortality" period, have been burned in and had all failed parts replaced. Generally they will last a very long time. The only problem is a lack of factory warranty - usually 90 days instead of a year or two.
