What should I do if my computer isn't working right?

If your computer is not working correctly, the first thing you should try is to check that all of the cables are securely connected. Make sure that the power cord is plugged in and turned on. Check that the monitor is receiving an appropriate signal from the computer. Try resetting the system by pressing the power button for 10 seconds or holding down the power button while restarting. If none of these steps work, it may be time to take the computer to a technician for further diagnosis.
