Solutions to common computer problems, solutions to common computer problems

In the process of using the computer, it is inevitable that some problems will be encountered and the failure will be caused, so what should I do? Don't worry, the following will introduce you to the solutions to common computer problems, welcome to read!

windowsupdate

Sometimes, what seems complicated can be solved in the simplest way. So, if there are some problems with the Windows system, we might as well run Windows Update first, get all the patches ready, or try a new one. driver, the problem will probably be solved.

Computer too slow?

In addition to the hardware factor, the speed of the computer is also closely related to the system. First of all, you can check whether the disk space is full, especially the C drive of the computer, and it is recommended that the application should not be installed on the C drive. In addition, it can reduce the startup items of the system to achieve a faster boot speed, such as some software automatic update applications, which can be canceled from boot startup.

Slow internet speed?

If your network speed is too slow, you may wish to log in to such a speed test** to test the network speed, if the speed is really slow, and then check the router, if it is normal, you can call** to the broadband service provider to consult whether there is a problem with the network service. If you can't connect to the network all the time, it may be a problem with the network card hardware, try to install the latest driver first, if it still doesn't work, it may be a hardware problem, and you need to replace it.

The computer keeps restarting

The computer keeps restarting is usually caused by two aspects, one is that it is infected with a virus, so we can enter the F8 safe mode to check for viruses. If the situation persists, it may be caused by poor hardware heat dissipation, or the computer power supply fan, or the motherboard CPU fan does not rotate.

Block pop-up ads and trojans

Many times, when we install software, we will accidentally install some junk plug-ins, resulting in slow down or pop-up ads, through some PC Manager software, you can easily remove these junk plug-in content, such as QQ PC Manager. Alternatively, you can install this type of protection software to block Trojans or phishing**.

"There is a problem with the security certificate of this **".

If the message "There is a problem with this **'s security certificate" frequently appears when you use a browser to surf the Internet, it may be due to the incorrect system clock setting. Normally, the CMOS battery of the computer motherboard will keep the clock running all the time, and if it fails, you can try to replace the motherboard battery.

The motherboard is a key component of the entire computer and plays a vital role in the computer. If the motherboard fails, it will affect the whole motherboard.

Common fault 1: No display is displayed when the computer is turned on.

There is no display when the computer is turned on, and the first thing we need to check is the BIOS. The BIOS of the motherboard stores important hardware data, and the BIOS is also a relatively fragile part of the motherboard, which is extremely vulnerable to damage, and once damaged, the system will not be able to operate.

Class failures are generally caused by the destruction of the motherboard BIOS by CIH viruses (of course, it is not excluded that the motherboard itself is faulty and the system cannot be operated. ）。Generally, all the data in the hard disk will be lost after the BIOS is damaged by the virus, so we can judge whether the BIOS is damaged by detecting whether the hard disk data is intact

1.Because there is a problem with the motherboard expansion slot or expansion card, the motherboard does not respond and does not display when the expansion card such as a sound card is plugged in.

2.If the CPU frequency set in the CMOS is not the same for the jumper-free motherboard, it may cause a no-display failure, which can be solved by clearing the CMOS. Clear the CMOS jumper is generally near the lithium battery of the motherboard, its default position is generally short circuit, as long as it is changed to short circuit for a few seconds to solve the problem, for the old motherboard, if the user can not find the jumper, as long as the battery is removed, after the boot display enters the CMOS setting, then shut down, the battery up also achieves the purpose of CMOS discharge.

1.Memory Failure: Turn on the computer, automatically restart from time to time, or the computer beeps or the system is not running.

2.Graphics card failure: During the use of the computer, the sound is very normal, the monitor suddenly does not display, and sometimes even the screen is blurred, which should be considered.

Fault: During the use of the computer, it suddenly fails to turn on, and the monitor does not display, and the problem of the graphics card is ruled out, then there is.

4.Hard disk failure: The operating system is normal, but the opening of the drive letter is very slow, or it cannot be opened at all, or the disk is not scanned.

5.Sound card malfunction: It is also very common for a computer to have a certain software installed and suddenly there is no sound, usually the software.

It may be that the computer has not moved for too long, and you have entered leisure, press the power button to try. You can right-click on the desktop and select "Properties", and click the "Power" button under the "Mask Saver" tab to set it, it is recommended to turn off hibernation, and change turning off hard disk and system standby to "never".

You can uninstall the game.,Formatting is an operation on the disk.,After formatting, the data on it is gone.。

If you can enter the operating system after the interface, it means that there is only a problem with the boot device settings, and you can save it after changing it.

If you can't get into the system, there is a problem with the hard disk or operating system, and you need to repair or reinstall the operating system, and then change the boot settings.

Poor contact of memory modules (mainly caused by too much dust inside the computer, which often occurs in old computers) and hard disk failure are the most common blue screens on the computer. Try opening the computer case, unplugging the memory module, cleaning the lower slot, and cleaning the gold finger of the memory module before installing it back.

Because your computer is infected with a virus, it is the virus that causes the computer to be restarted, you hurry up and use genuine antivirus software, and then upgrade to the latest, and then antivirus, and there will be no automatic restart after killing!

See if there is a hardware alarm, if there is no alarm, you can reinstall the system.
