Hard Drive S.M.A.R.T Readings

Just recently I’ve started to have a few problems with my desktop pc, mainly apps and browsers slow to open.
The hard drive is a few years old so I thought it might be on its last legs. I’ve run the WD Diagnostic Tool and below are the test results.
I’ve read the help notes but I’m still somewhat confused whether the results are showing a problem with the drive or not.
All the attributes have green ticks against them, so does this mean they are all ok? Any advice would be gratefully appreciated.

Thank you
