What should I do if I delete something on the C drive, and then the computer can t turn on the blue

1. Blue screen problem.

1 Software compatibility issues cause a blue screen on your computer.

If the driver is not compatible with the hardware and may lead to the blue screen phenomenon, it is recommended to install the driver in the hardware gift disc (to match the operating system used), and the driver does not need to pursue the latest!

There is no blue screen phenomenon after using the computer for a long time, and one day suddenly there is a blue screen, which is generally caused by memory problems caused by too much dust in the computer (solved by the methods mentioned below) and software and system compatibility problems. Or use the Windows System Restore feature to directly restore the system to the previous restore point for detection!

2. Poor contact of the memory module or memory damage causes the computer to blue screen.

During the operation of the system, almost all the high-speed data access operations are carried out in the memory, if the memory module is not in contact or damaged, the access of system data will be problematic, which can easily lead to the system blue screen and crash! Generally, poor contact of memory modules is caused by excessive dust accumulation in the computer, or the memory is not plugged in tightly! If you have two internal memory, you can unplug one of them for detection, and if you reinstall an official Microsoft original operating system and still get a blue screen, then you can definitely determine that it is caused by a hardware problem!

Solution: Clean the dust in the chassis, unplug the memory module, wipe the gold finger with an eraser, and then plug it in again.

3. Virus Trojans cause a blue screen on the computer.

Nowadays, there are more and more types of virus Trojans, there are various ways of transmission, and it is impossible to prevent them, some virus Trojans infect system files, causing system file errors, or causing system resources to be exhausted, and may also cause the occurrence of blue screen phenomenon, It is recommended to install antivirus capabilities to emphasize antivirus software, such as Kaspersky, NOD32, etc. for detection, but as we all know, the update speed of antivirus software is difficult to catch up with the speed of the virus, which requires us to practice the ability to manually check and kill viruses, and it is recommended to use process Explorer forcibly terminates malicious processes (Microsoft's officially recommended process monitoring tool).

An example of using Process Explorer to detect and kill viruses: the solution to the problem that the IE homepage cannot be modified by yourself after it has been maliciously modified.

4. Bad sectors on the hard disk cause the computer to screen blue.

Like memory, the hard disk will also carry some data access operations, if there is a bad sector in the area where the access and reading system files are located, it will also cause the system to fail to operate normally, resulting in a system crash and a blue screen on the computer!

Solution: Reformat the system partition after backing up important data (there will be an option to format when reinstalling the original Windows system), if the format is successful, it will not affect the use, otherwise you can only discard the partition or replace the hard disk.

C disk is called the system disk, the operating system is installed in the C disk, even the operating system has been deleted and the computer must not be used, only to reinstall the system, if there is a backup in the computer, please press and hold the F11 key while restarting the computer, according to the interface guidance operation, generally can be automatically reinstalled and restored.

To confirm whether the black screen is caused by a hardware failure or a software failure, if the phone does not have important data, it is recommended to restore the system and try to fix it. If the recovery system is still in trouble, the hardware damage is more serious!

1. The C drive of the computer is the partition where the system is located, and deleting files will cause the system to crash, and the system may be damaged.

2. In this case, you need to reinstall the system to start. Let's reinstall the system.

3. After the system is solved, it is necessary to pay attention to the files of the C drive. All software should be saved in a partition other than the C drive to avoid file loss due to system crash.

1. The power supply is faulty, the computer cannot be turned on, and the computer is found to have no response and a black screen. And listening to the sound of the CPU fan turning in the case, then this situation is likely to be a power supply problem. The power cord is in poor contact or the power supply is burned.

Solution: Check whether the power cord connection is normal, if it is normal, consider replacing the power supply to troubleshoot, borrow a power supply or go to the repair computer to replace one is to try.

2. Poor contact of memory modules. If the power indicator is normal after turning on, there is also a fan turning sound in the case, but the monitor does not respond, and the computer does not make a sound. There are two reasons why this is certainly possible:

The CPU and the memory module are not in good contact, and the memory module appears more often. Solution: Unplug the memory module and reinstall it, and then see if it can solve the black screen at boot.

Or use a dry brush to sweep the memory slot, use an eraser to wipe some of the gold fingers on the memory module, wipe the oxide film, and then plug and unplug it several times, it may not work once.

The memory module, PCI-E or PCI (graphics card, network card, sound card) are not properly connected, or the operating frequency does not match the external frequency of the motherboard. As a result, the machine cannot be started normally, and the second is that the boot screen is black and the display does not respond. Workaround:

Restore the CMOS to its default setting by discharging the CMOS (unplug the power cord before discharging).

In addition, due to the dust in the air, metal floats, it is easy to oxidize, and some computers with a long service life are most likely to have poor memory contact resulting in a black screen at startup.

3. The motherboard is faulty, and the monitor screen responds after booting, but it stops when English letters appear after the black screen is displayed (that is, the computer cannot complete the self-test when it is turned on).

4. There is a prompt sound when the boot is turned on, the screen is black after booting, and the monitor does not respond, but it is accompanied by some sounds, and there is a buzzer on the main chassis that sends out a prompt sound. The location of the fault can be determined based on the sound, so there are two possible causes:

A long two-segment sound (drip, bibi) is likely to be a discrete graphics card with poor contact. After turning off the power, unplug the graphics card, reinstall it, and turn it on.

When booting up, it may be that the memory module is not installed correctly, turn off the power and unplug the memory module and reinstall it several times.

Windows should be reinstalled using a USB flash drive, CD-ROM or portable hard drive.
