Quick PC Recovery

I spend a lot of time assisting users on how to recover from pcs.  #1 is always Reboot (usually holding down the power button for 5 seconds. #2 Start system in Safe Mode to determine is something software related is causing OS conflict, #3 my goto usually after about of 30 minutes to 1 hour of troubleshooting is a system restore.  I'm usually back in business, by then.  I hope this helps you!!!
