My Computer Won’t Turn On
- Begin by checking the power cord to confirm that it is plugged in securely into the back of the computer case and the power outlet.
- If it is plugged into an outlet, make sure it is a working outlet. To check your outlet, you can plug in another device to check if it is functioning.
- If the computer is plugged in to a surge protector, verify that it is turned on. Sometimes you have to reset the surge protector by turning it off and then back on. You can also plug another device into the surge protector to verify that it’s working correctly.
- If you are using a laptop, the battery may not be charged. Plug the AC adapter into the wall, wait a few minutes, then try to turn on the laptop.
An Application is Running Slow or is Frozen
- Close and reopen the application.
- Try updating the application. Click the Help menu and look for an option to check for Updates. If you can’t find this option, run an online search for updating the application.
Sometimes an application may become stuck, or frozen. When this happens, you won’t be able to close the window or click any buttons within the application.
- Force quit the application. On a PC, you can press (and hold) Ctrl+Alt+Delete on your keyboard to open the Task Manager. On a Mac, press and hold Command+Option+Esc. You can then select the unresponsive application and click End task (or Force Quit on a Mac) to close it.
- Restart the computer. If you are unable to force quit an application, restarting your computer will close all open apps.
All Programs are Running Very Slow
- Run a virus scanner. You may have malware running in the background that is slowing things down.
- Your computer may be running out of hard drive space. Try deleting any files or programs you don’t need.
My Mouse and Keyboard Stopped Working
- If you’re using a wired mouse or keyboard, make sure it’s correctly plugged into the computer.
- If you’re using a wireless mouse or keyboard, make sure it’s turned on and that its batteries are still good.
The Computer is On but the Monitor is Blank
- Is the monitor plugged firmly into a working wall socket or power strip, and is the power strip turned on? If so, try plugging the monitor or power strip into another wall socket.
- Is the monitor’s power button switched to the “ON” position?
- Check to see that the video cable is plugged firmly into the back of the monitor and to the video output on the back of the computer.
- If that doesn’t work, try removing the existing cable and replacing it with a known working one.
- Borrow a working monitor from another PC and hook it up. If the monitor doesn’t work, your video card may not be working. From this point, seek professional assistance to diagnose the problem more closely.
My Sound is Not Working
- Check and make sure that the speakers are turned “ON” and that they have power.
- Check and make sure that the speakers are plugged into the correct audio jack. It is usually color coded and will most likely be a green color.
