HI,

I have a lenovo think pad from 2013 with windows 7.

I can start up the laptop but then after 2-3 minutes even in safe mode, the computer makes a rhythmic computer working noise (like its processing info) and repeats on a loop. I dont even have to log in for this to happen. The green cylinder light is on constantly when this happens. It slows to the point of one action every two minutes.

I have done a disk check during start up and it found some unreadable files. This rhythmic noise happened on and off while the check was happening even. I think it slowed down the disk check even though it was able to complete. Several minutes on each bad file. The check did not solve the problem.

How do I solve this problem?

Try these free hardware diagnostics:  http://www.carrona.org/hwdiag.html

Start with the hard drive tests, but complete ALL of them - and please let us know the results.

I suspect the hard drive because of the disk check results.
The disk check actually doesn't check the disk - it checks the file system on the disk.
So, unreadable files may (but also may not) be due to a failing hard drive.

Additionally, a system that's taking a long time to do things and that also has the hard drive chugging along (as evidenced by the green cylinder light being on constantly) are symptoms of a failing hard drive.  What it's doing is re-reading/checking/writing the sectors that it's having a problem with.

 

Good luck!
