Possibly not, but there is always a great chance it had negative affect on stability.

It was only to inform on the possible risks you may have
If you don't want to wipe your hard drive, I would strongly advice to be careful with anything you do on your system, not only online but also offline. Since you're probably not aware of what the previous owner did, there is a chance that something else nasty spies on you. Not trying to be paranoia, but I've seen this happen too many times.

Since there are over 10k+ events about your hard drives health, I would suggest to run some hard drive diagnostics

Diagnostics Test

 HDD TEST

   Note

Please run HDTune first, in the order posted!

Run HDTune to

• check the health,
• scan for errors, no quick scan but full scan
• run a benchmark.

It may take some time, but please take the time you need to perform it properly.
When above is done please make screenshots of the following

• the health,
• the error scan,
• the benchmark incl. following
  • transfer rate,
  • access time,
  • burst rate,
  • cpu usage.

Run SeaTools DOS to check the integrity of your HDD. SeaTools for DOS and Windows - How to Use - Windows 7 Help Forums
Run the long test.

   Note

Do not run SeaTools on an SSD as the results will be invalid.

Make a photo of the result and post it.
