Simple solutions to prevalent issues

Using simple troubleshooting techniques, like closing and reopening the program, problems can be fixed most of the time. Before resorting to more extreme measures, it’s important to try these simple solutions. If the issue is still not fixed, you can try other techniques for troubleshooting.

Problem: The power button won’t start the machine

Solution 1: If your computer fails to start, start by checking that the power cord is securely plugged into the back of the computer case and the power outlet.

Solution 2: Make sure it is a working outlet if it is plugged into an outlet. You can plug another electrical device, such as a lamp, in to check your outlet.

Solution 3: Verify that the computer is turned on if it is plugged into a surge protector. By switching it off and then back on, you may have to reset the surge protector. To verify that it’s working correctly, you can also plug a lamp or other device into the surge protector.

Solution 4: The battery may not be charged if you are using a laptop. Plug the AC adapter into the wall and then try to switch the laptop on. You may need to wait a few minutes and try again if it still doesn’t startup.

Problem: An application is slowly running

Solution 1: Close the application and reopen it.
Solution 2: Framework update. Click the Help menu to do this, and search for a choice to check for updates. Another suggestion is to run an online search for program updates if you don’t find this option.

Problem: A request is frozen

An application can often become stuck or frozen. You won’t be able to close the window or press any buttons inside the program when this happens.

Solution 1: Compel the program to terminate. On a PC, to open the Task Manager, you can press (and hold) Ctrl+Alt+Delete (Control, Alt, and Delete keys) on your keyboard.

Click and hold Command+Option+Esc on a Mac. You can then pick an unresponsive program, and you can close it by pressing End Task (or Force Quit on Mac).
Solution 2: Machine reset. If you are unable to compel an application to leave, all open applications will be closed when you restart your device.

Problem: All the programs run slowly on the machine

Solution 1: Run a scanner for a virus. In the background, you can have malware running that slows down stuff.

Solution 2: Your machine can run out of room for a hard drive. Try to uninstall files or programs that you do not use.
Solution 3: You should run the Disk Defragmenter if you are using a PC.

Problem: There is a frozen machine

Your machine can become totally unresponsive, or frozen, sometimes. You won’t be able to click anywhere on the computer, open or close apps, or access shut-down options when this happens.

Solution 1 (Windows only): Restart the explorer on Windows. Press and hold Ctrl+Alt+Delete on the keyboard to open the Task Manager to do this. First, from the Processes tab, find and pick Windows Explorer and press Restart. In order to see the Processes tab, you can need to select More Information at the bottom of the window.

Solution 2 (Mac only): Finder restart. To do this, on your keyboard, press and hold Command+Option+Esc to open the Force Quit Applications dialog box.Then, find and pick the Finder, and then press Reload.

Solution 3: Push the Power button and keep it. The Power button, commonly represented by the power symbol, is generally located on the front or side of the device. To force a computer to shut down, press and hold the power button for 5 to 10 seconds.

Solution 4: You should unplug the power cord from the electrical socket if the device is still not switched off. You might be able to remove the battery if you’re using a laptop, to force the device to shut off. Note: After trying the other suggestions above, this approach should be your last resort.

Problem: The keyboard or mouse has stopped working

Solution 1: Make sure that a wired mouse or keyboard is properly plugged into the device if you are using it.
Solution 2: Make sure that it’s switched on and that its batteries are charged if you’re using a wireless mouse or keyboard.

Problem: Sound does not work

Solution 1: Check the degree of volume. To make sure the sound is switched on and the volume is up, click on the audio button in the top-right or bottom-right corner of the screen.
Solution 2: Check the controls for the audio player. A lot of audio and video players would have different audio controls of their own. Make sure the sound is switched on and that in the player the volume is turned up.

Solution 3: The cables are tested. Ensure that the external speakers are connected, switched on and connected to the correct audio port or USB port. The audio output port will normally be green if your device has color-coded ports.
Solution 4: To find out whether you can hear the sound through the headphones, attach the headphones to the monitor.

Problem: There is a blank screen

Solution 1: It is likely that the machine is in sleep mode. Click the mouse or to wake it, press any key on the keyboard.
Solution 2: Make sure that the display is attached and switched on.
Solution 3: Ensure that the machine is switched on and plugged in.

Solution 4: Make sure the display cable is correctly connected to the computer tower and the monitor if you’re using a laptop.
