Have you tried switching it off and then on again?
The question may sound like a cliché, but restarting troublesome technology can often fix a problem you may be experiencing. As a computer or printer remains switched on and continues to be used, it builds up temporary files and settings that can eventually slow down or inhibit your ability to use the machine. Therefore, switching the machine off clears these congesting files, and the machine is able to "breathe" again.
The machine must be completely switched off. Putting it into standby, or hibernating the computer, will not work.
If restarting the machine did not help, these self-help guides may be useful.
