Another spinning ball problem

The infamous spinning beach ball started to appear last week when I noticed my iMac 27 slowing down considerably. My iMac runs pretty much slow when starting up, opening Excel or Word programs, checking emails, browsing the web and pretty much everything else. When it goes into the sleep mode I am not able to reawaken it. Generally during reawakening it will be a couple minutes before the cursor arrow appears and then the beach ball appears on the blank screen. I have to unplug the iMac and replug and restart. It is still slow.
I have tried to run virus scan but not sure if successful as system goes to sleep.
I have the iMac 27, late 2015, MACOS Sierra v10.12.2, 1.6GHz Intel Core i5, 8 GB ram 1867 MHz DDR3.

Thanks for any help,
The Duke

If it need repairs then you will have to boot to the Recovery drive and use Disk Utility from there.

Do you hear lots of HD activity when it is beach balling?

How do I know if/what needs repairs?

Should I run the disk utility 1st?

No HD noise that I can detect.

Correction to my model. It is the iMac 21.5 late 2015.

Thanks in advance,

Disk Utility will tell you if the drive needs repairs.

Be aware that you cannot repair a drive from which you are booted, hence the mention of the Recovery Drive
