Try this
Reset SMC https://support.apple.com/en-us/HT201295
Reset NVRAM https://support.apple.com/en-us/HT204063
Turn on the Mac holding Shift to startup in Safe Mode. It's a bit longer boot because macOS does some maintenance under the hood that can solve some problems.
If it doesn't work, you should try a reinstall of macOS.
Try also run the Apple Hardware Test https://support.apple.com/en-us/HT202731 and check if shows any errors.
Check if your HD is not failing. Maybe replace it with an SSD and you'll also get a lot faster machine.
