The following solutions will help you quickly handle emergencies 5 often occurs for the PC, such as a broken screen, accidentally deleted an important file or infected.
The screen is broken
Suppose you are working with a laptop in his lap and accidentally drop the machine to the ground causing the screen is broken, do not worry but should quickly apply the following solutions. The first thing to do is to check if the external display also damaged the more important components like graphics cards are affected or not. If only a cracked screen protective glass and still function normally, you continue to use the computer as normal to see if other problems occur not.
If not detected malfunctioning clear but unusual activity monitor, try attaching an external monitor to the laptop. The computer will need to have HDMI, mini-HDMI, DisplayPort, mini-DisplayPort, DVI or VGA and an external monitor or TV to do this. Some laptops have an external display mode must be activated operations, often using the Function keys. If your laptop display well on an external monitor, you only have problems screen damaged, not only is more important.
Can use the external display when the laptop screen is broken.
Where cracked screen lightly along the edge, you can continue to use the laptop as usual but should not move back up your laptop or bring a laptop with you because the screen if pressed up, cracks may be larger . If you have available an external monitor, you can use the laptop as a temporary desktop.
If you still want to replace the new screen, you have two options: either individually rather taken or may bring laptops to edit in a reputable repair shop (or in the original company if the laptop warranty extension for the accidental damage). Self replacement laptop screen for basic easy to implement than you think, but if there are such ultrabook laptops specialized or MacBook, you should bring a professional salon. Ultra-thin screen as the screen on MacBook Air ultrabook and can be very difficult to replace and is generally recommended not replaceable.
Deleted important files
There are two types of files "important": kind of important files on your own (such as the personal data files) and important type computer (the file system). Hopefully you do not have a habit of "fiddling" the root directory of PC and carelessly delete files describe the system. However, sometimes these files are lost due to critical system conflicts, infected with malware or a virus scanner "too aggressive".
In this case, the first thing to do if you accidentally hit the delete a photo or a document is important to take viewers can find them not. Open Windows Explorer and type the file name in the search box in the upper right corner. Probably you did not delete the file but just move it to another folder for inadvertent clicks.
If you can not find a file search command, open the Recycle Bin is located on the main screen and then find the file. If the Recycle Bin has a lot of files, right-click in the window, move the cursor on and select Sort by Date Deleted. The file is deleted most recently appears at the top of the window.
Find and restore deleted files in the Recycle Bin.
Assuming this does not bring efficiency, try using recovery software tool like Recuva deleted files to recover lost data.
If your file is not in the Recycle Bin and is not found by the tool Recuva, you can recover files easily from the backup. Windows 7 automatically creates the "earlier version" of the file, but in Windows 8 you'll have to open manually using a feature called File History to get the previous version of the file.
In Windows 7, open Windows Explorer and find the folder containing the files looking for. Right-click and select Restore previous folder. You will see a list of backup directories listed by date. Choose a backup was created earlier that you remember to delete and select Restore.
If you can not find the file or recover deleted files from Windows File History, you are not completely hopeless. If you regularly backup your computer, you can try to find the file on the backup drive. In case if your backup drive is a cloud service like Dropbox, Google Drive or OneDrive, you can recover files from websites that cloud services. If the file is not deleted personal files which is an important system file, you will probably be corrected by the System Restore tool, or even going to install Windows from scratch.
Computers contaminated water
Most computer users may also be seen this case, especially those who often drink while working and then suddenly the water stained keyboard. Liquids will damage the electronic components for liquid substances such as salts and minerals are electrically conductive. Technically, pure water you pour into the computer can be completely not harmful. If you turn on the computer when the computer was something sticky liquid, the machine can be touched by the power circuit accidental liberal diversion. Therefore, you first have to do when the computer is shut down in water as quickly as possible, unplug it and remove the battery immediately (if possible). As fast as you can get out of touch phones.
Disassemble all components of the PC as much as possible when the liquid into the machine jammed, of course, after the electricity is off.
When the computer is off, you have to remove all the cables, components and spare parts for the drive and the computer turned upside down. If it is a laptop, you must avoid the liquid to flow into the close screen. If it's a desktop computer, you should let it lie on the edge and not turning the machine completely. Rotate the computer to the interference of water (eg, if water leaks water onto the keyboard on the left side, turn the machine tilted to the left). You can wipe the liquid on the outside machine with a soft dry cloth fibers.
When the liquid has flowed almost all, you should disassemble the PC as many parts as possible. If possible, go down through the machine so everything is drying up.
If not, do not try, but maybe you should at least picking out the key from the keyboard to the liquid flow out. If other liquids are foreign interference, you should clean the machine with a cleaning agent circuit, because many drinks often sticky and cause corrosion, will cause damage the inside of the PC. After the electricity is off, disassemble and clean the PC, you let him do it and wait. Wait as long as possible, ideally about 2 days or at least 1 week. Then, try to open it up.
Not connected computer networks
Nothing bored by sitting at a computer to surf the web, watch video online that "the network is down." In addition to transmission reason as the company provides network services fail, the following is what you can do if you find yourself in a situation no Internet connection.
There can be 4 causes no Internet connection, depending on the type of connection you are using (wired or wireless). One is due to ISP, the problem may be due to collapse in local networks, local or regional. The two are due to malfunctioning modem. Three are due to router (router) wireless damaged. And four are due to your computer.
To check the ISP has been disconnected from the network or not, go to the web (using 3G on the phone because then unable to access the Internet using the computer) and select your company provides. Alternatively, you can call the company ISP and ask them to check the incident. If not by the ISP, you should continue to check the modem and your Wi-Fi router.
Take steps to test sequential lost cause Internet connection.
First, unplug the router, and then power down the modem. Wait at least 30 seconds and then plug the modem back and wait for another 30 seconds, then plug the router. Restart your computer and network connection will be. If not, check to see that no matter what router by connecting your PC directly to the modem with an Ethernet cable. If yes, the network behind the router steps were problems.
If still no network after this step, your modem may be the main problem is that the network cable or. Try a different cable if available. If all things are working well, the problem may be in your PC. The easiest way to test is to try to connect to the Internet using a device such as a PC, phone or tablet. If you can connect, then make sure your PC has problems. Check that the network card has not enabled by going to Control Panel> Device Manager> Network adapters.
Right-click the network adapter and select Enable if not already enabled. Another way is to choose Properties and check device status (device status) if the device is not working properly ("This device is working đúng"). If the device is not working properly, you need to update the driver (driver) for it. Select the Driver tab and select Update Driver ... If you are using Wi-Fi, check that you have not turned on Wi-Fi. Some laptops have separate buttons or to use the function key to toggle Wi-Fi.
Computers infected
Virus software can scan your computer has expired, can you click on the option box irrelevant in antivirus program, you may have downloaded the wrong thing to download. But either matter, can confirm your computer has become infected because unusually active and it will quickly spread.
In this case, the first thing to do is to check whether yours is really infected or not. Viruses and malicious software (malware) is often present in multiple ways. You may have seen ads poisoned, your PC may be very slow operation or may be conflicting software frequently, unless you have anti-virus program indicating the presence of a kind certain viruses.
Before the implementation of other things, you disconnect the network, then what you need to do is update your antivirus software.
Next, restart the PC again according to Safe Mode by pressing F8 repeatedly until you see the Advanced Boot Options menu. Use the arrow keys to select Safe Mode with Networking and press Enter.
Viruses and malware are often present in many ways.
Once in Safe Mode, use an anti-virus program and an anti-malware program to check the drive. You need to install a new antivirus program available even if a virus program on the PC, because the old program is clearly a lack of protection. You can do this by loading the program on a thumb drive and install from there so no need to connect your computer to the Internet. In addition to antivirus scanning, you should also check with malware programs like MalwareBytes.
The hope is that the anti-virus and malware software will be able to find and destroy them. But if these programs are not effective or conflict while trying to run (because some viruses are very smart and know when the program is designed to destroy them), you may need to install Windows and restore the files, settings from the backup was created.
