There are numerous causes for a computer to suddenly “freeze” or stop functioning. Since computer programmes have grown so complicated, users periodically encounter issues even when carrying out routine chores, and most of the time there isn’t much we can do about it. Restarting the computer is your best option if it stops responding to keyboard input.

Clear the vents on the computer

Your computer’s vents will eventually get noticeably clogged with dust and debris. Air cannot properly flow through your computer casing when the vents are blocked, which might cause your computer to overheat. In order for your computer to cool down, clean out the vents. If there isn’t any significant harm, it should begin immediately away the following day.

Examine the data and power cables.

Power and data wires from the motherboard and PC power supply connect to your hard disc. Check these cables at both ends by opening your case.

Before assuming that there is something wrong with your device, go through the following steps to eliminate all other causes: 

Try Another Power Source

Ensure that your device is plugged in and turned on. If both these conditions are met and your PC still won’t turn on, try another power outlet. It may be that the issue lies in insufficient power supply, causing your computer to not turn on.

Ensure that your monitor is connected 

If you can hear your computer booting up, generating all the telltale whirring sounds but can’t see any output on the screen, it may be that your monitor is not properly connected to the rest of the system. Make sure that the cable connecting your monitor to the PC is properly set in place. If you still do not receive any output on your screen by then, try connecting another monitor to your computer system to check whether or not your original monitor is still functional.

Unplug Your Devices

Although rare, some devices may cause interference, and this may be what is preventing your computer from booting up. Disconnect devices such as printers and external hard drives, and boot up your computer again.

Check For Beep Frequency

When a computer is running into an issue that causes problems with start up, you may hear a series of beeps or even one long beep – this likely means that your computer has likely run into an issue. 

You may check the manufacturer’s website to understand what this means, but at this point, it is best to contact a professional.

Do not be alarmed by this, first take a look at the following:

Check the monitor’s physical connections. Make sure that your monitor is properly plugged in – it may be that an insecure connection is causing the screen to appear blue.

If this still does not work, disconnect every external device attached to the computer, excluding the keyboard and mouse, and see if the problem still exists. It may be an interference issue.

If the problem persists, get in touch with a professional. It may be that your computer is displaying the blue screen of death – showing that your computer is broken beyond repair. But before jumping to such a conclusion, it is best to consult a professional.

Try the following steps: 

1. Make sure your device’s cords are not damaged in any way.
2. On your computer, try a different USB port.
3. If your mouse is battery-powered, check if the battery is fully-charged or ensure that there are new batteries in your mouse.
4. Plug the device back in after unplugging USB cords and wait a few seconds for Windows to finish unloading the device driver.
5. Make sure the port has electricity if you connect the mouse to the PC using a USB hub. If it still doesn’t work, try taking out the USB hub and connecting the mouse straight to a USB port on the computer.

• Double-Check Your Hardware

Make sure to examine any hardware components that could be the source of this issue before examining or altering any settings on your laptop or computer. If you use a wireless mouse, check the battery life, USB ports, and mouse cable.

• Double-Check Your Mouse’s Surface

Examine the mouse’s resting surface if the mouse itself appears to be in good condition. There could be blemishes or uneven surfaces on your desk. If you use a mouse pad, it may be worn out and provide inaccurate information about your mouse’s motion.

• Change Touchpad Settings

The cursor will move at the slightest touch if the touchpad sensitivity on your laptop is set too high. You ought to check the sensitivity setting.

• Disconnect Other Devices

A joystick, graphics tablet, or other input device connected to your laptop or PC may be the cause of the problem. Some of these have the ability to manipulate the cursor, which can spark conflict between them as they vie for dominance. To determine which device is causing the problem, you can unplug each one individually and reconnect them one at a time. Alternatively, you can disable each device when not in use.

• Update Drivers

With time, a mouse’s driver may grow outdated, leading to reduced functionality. Installing the correct drivers can help your mouse work properly again. 

• Clean Your Mouse

If nothing else has worked, it may just be that your mouse is in need of a good cleaning. Dirt may be interfering with your mouse’s movements, causing it to work erratically. So clean it with some rubbing alcohol and try again.

You may be encountering a touchpad driver issue, so updating or reinstalling your driver may solve your trackpad issues.

One of the most common causes of a laptop touchpad not working is that you’ve accidentally disabled it with a key combination. 

Remove Your Mouse to Activate the Touchpad

Some laptops are configured in such a way that the tracker gets disabled when a mouse is connected to the computer. So make sure to disconnect your mouse before trying to use the trackpad again. 

Click on Start, then on Settings, next on Update & Security and then Windows Update, and then choose “Check for updates”. If updates are available, install them.

Safe mode enables you to start your OS in a very minimal configuration so you can perhaps find and fix an issue you may be facing.

Your screen resolution can appear a little odd while in safe mode, some programs might not function properly, or your computer might perform a little slower than usual. This is quite normal; it’s just a result of some drivers not being active.

If a file is missing from your computer or you accidentally changed or destroyed it, you can try to restore it from an earlier version or, if you’re using Windows backup,  you may use a backup. The copies of files and folders that Windows automatically stores as a part of a restore point are known as previous versions. If you are still unable to restore or even find the file you want, you may be in need of more advanced recovery services.

There are many reasons as to why you may not be receiving emails. First, check your internet connection and troubleshoot your connection problems. If you are still not receiving your emails, it may be that there was an issue with the sender’s email. Verify that the sender had the right email address. If the issue still persists, you may need more advanced email solutions.

It may be that you are unable to receive attachments because you have insufficient storage space and the attachment is too large. Try freeing up some more storage and check if you are able to resolve the issue. Other common issues include the attachment not being of the right file type, the file containing a virus…

Your email account won’t let you log in. You could receive a warning saying that your username or password is invalid when you attempt to log in. As is frequently the case after gaining access to your email account, a fraudster may have changed your email password in this instance.

The sent-messages folder appears strange. You may have unsolicited scam mails in your sent messages folder. In the event that you never erased your sent messages, the folder can be empty.

Your contacts accuse you of sending them spam. If your contacts start messaging you to question why you’ve been sending them spam, that’s probably a sign that a hacker has accessed your email account and is making use of it to send messages in your name.

1. You have a slower internet plan, so you may want to upgrade to a plan that allows you to use more data faster. 
2. Your provider’s network is crowded, meaning that there are too many users on the network for it to function optimally.
3. You used more data than allowed by your internet plan. You may have a limited amount of data allowed at a certain speed before your connection reverts to a slower speed.
4. Your Wi-Fi signals are spotty. It may be that connectivity is bad because you are in an area that the Wi-Fi cannot properly reach.
5. Your connection is being throttled by your provider. At times, internet service providers may purposefully slow your connection.
