You need to find and judge the reason of blue screen according to the blue screen code prompted by the screen.
You can refer to the following methods to try to solve it:
First, try to switch the monitor to another computer to see if it works properly. If it is normal, it means that there is nothing wrong with the monitor, and you can continue to check the computer. If the fault still exists, there is something wrong with the monitor. Ask professional maintenance personnel to check and repair.
If the monitor is normal, or the laptop cannot check the display, you can investigate the following reasons:
You can follow the following general solutions from soft to hard, try to repair the system or detect and eliminate hardware faults. Please refer to:
Turn it off first, then turn on the main chassis, unplug the power cable and data cable of the hard disk, plug it in after 2 minutes, and try again. Then repair the system as follows:
Press F8 key continuously to enter the system operation menu when booting (in the case of WIN8, WIN8. 1 and WIN 10 systems, press and hold the power button to turn it off after seeing the boot screen, and you can enter WinRE {Windows Recovery Environment} after repeating it for about three times in a short time, but some users may need to directly disconnect the power. In this way, the advanced recovery interface should appear after booting. In the advanced reply interface, select Enter Safe Mode.
First, by soft: try to repair the operating system:
1. If there are external devices, such as USB flash drive and USB mobile hard disk, or there is a memory card in the card reader, please take it out and try again.
2. Remove and install non-standard components, such as memory and hard disk. It is recommended that you contact the operator to remove the added component and try again.
3. Enter the computer BIOS check? Whether the hard disk can still be recognized in the BIOS, and select the option of "Load Best Default Value" or "Optimize Default Value" to restore the BIOS default settings, and then test.
4. Press F8 key continuously to enter the system operation menu (in the case of WIN8, WIN8. 1 and WIN 10 systems, after seeing the boot screen, press and hold the power button to turn it off, and repeat it for about three times in a short time to enter WinRE {Windows Recovery Environment), but some users may need to disconnect the power directly. So the advanced recovery interface should appear after booting), select "Last Correct Configuration" and restart the computer to see if it can be solved.
5. Press F8 key continuously to enter the system operation menu (in the case of WIN8, WIN8. 1, WIN 10 systems, after seeing the boot screen, press and hold the power button to turn it off, and repeat it for about three times in a short time to enter WinRE {Windows Recovery Environment}, but some users may need to directly disconnect the power. Advanced recovery interface should appear after booting), then look for "safe mode" and enter "safe mode". If you can successfully enter, click Start → All Programs → Accessories → System Tools → System Restore to open the System Restore dialog box and select "Restore my computer to an earlier time". In this way, you can use the system restore function of Windows system to restore to the restore point where you can boot normally before. (If any)
6. Install the CD or USB flash drive with the system, insert the CD-ROM drive or USB interface, restart the computer, and enter the CD-ROM installation system state or USB flash drive installation system state. After the startup interface flashes, do not choose to install the system, but choose to repair the current system (it may run for a long time, 2-4 hours), and wait patiently for the repair to be completed to see if the problem can be solved. (At the end of this paper, the method of setting U disk as the first boot sequence device is described in detail. )
7. Unstable hardware devices, outdated device drivers and interference from third-party programs can also lead to black or blue screens. It is recommended to enter the safe mode first, and evaluate whether the reason is the expired driver or the interference of the third-party program. At this time, please download the latest BIOS, sound card or graphics card from the computer manufacturer's website and update it to solve the problem.
If the above seven methods are ineffective, you can only reinstall the system.
Second, come hard: see if it is a hardware problem:
1, the battery of the motherboard button is dead, so the saving time will be lost after power failure, and the information will not be saved. Try a new battery.
2, the motherboard BIOS error, some motherboards have anti-intrusion mechanism. If the accessories have been replaced recently, it may also be caused by an error in the motherboard BIOS. The solution is to press the DEL key (or the key prompted by the boot screen) to enter the motherboard BIOS and initialize the BIOS setting information. Usually press F9 to restore the factory default settings, and then press F 10 to save and exit and restart the computer.
3. CMOS(BIOS) settings are wrong, mainly because there is something wrong with the options of software settings. After booting, you can enter the Bios for setting.
At this point, you can check whether your machine has a floppy drive, CD-ROM drive or other accessories [such as a graphics card]. If you don't have these hardware, but your computer has these settings, you can try to turn off these options or set them to be disabled.
[Note: CD/DVD/CD-RW drive: CD-RW device: floppy disk drive: floppy disk device: floppy disk device]
4. The original part of 4.cmos(BIOS) conflicts with the current hardware. Before the CMOS(BIOS) can discharge, there is a CMOS three-pin jumper next to the button cell of the motherboard, but generally two pins are connected together. At this time, you can pull out the jump cap, connect the two pins together, and discharge with the jump cap in the case of power failure [this process usually takes about 4 seconds]. And then restore it to its original state. Or unplug the button cell, put it upside down, wait for 5-6 seconds to discharge, and then restore it to its original state. After booting, you can enter CMOS(BIOS) to restore the default settings.
5. Whether the graphics card driver is not installed or damaged, and the solution; Update the graphics card driver, use the driver CD that comes with the computer or go to the graphics card official website to download the latest driver, update the graphics card driver, or go to the Driver Home website to download the latest version of the driver wizard and upgrade the graphics card driver; ?
6. If the hard disk can't be detected, you can try to change the data cable for the hard disk. If there is no cable, you can also try to switch the two ends of the data cable and change the interface on the motherboard. ?
7. If the hard disk is still invalid after changing the data cable, you can also try to unplug the data cable of the hard disk before starting the test. See if it will still be stuck on the LOGO screen. If you can pass the LOGO interface, it is estimated that the hard disk is out of order. Enter the BIOS to find the hard disk or enter the PE system to check the health of the hard disk. If the hard disk is unreadable or proved damaged, it must be replaced.
8. Poor hardware contact is mainly manifested in poor contact between the graphics card or memory chip and the motherboard. At this time, you can unplug the graphics card or memory module. Unplugging the graphics card or memory module will not affect the access to cmos interface when booting. At this time, if there is no error in CMOS(BIOS) setting when entering this interface, it can be concluded that it is a problem with the graphics card or memory stick. You can use a better rubber to wipe the part that touches the motherboard first, and the memory is also wiped with rubber.
9. There are conflicts between different storage blocks of hard disk and CD-ROM drive. You can check them one by one at this time. You can unplug the power cable and data cable of the CD-ROM drive first, and then try to check with only one memory.
10, check whether there are external devices connected to the machine. External devices such as USB flash drive and mobile hard disk may be plugged into the USB port of the computer and forgotten to unplug it, resulting in the failure of the motherboard self-test card. The solution is to unplug the extra external devices and restart the computer.
1 1, check whether the keyboard and mouse are connected backwards. This refers to the keyboard and mouse with PS/2 interface. Many people are careless and plug the interface of the keyboard and mouse backwards, which leads to the self-check error of the boot computer and even the screen is stuck. The solution is to turn off the computer first and then take over the keyboard and mouse again. Usually the purple interface is the keyboard and the green interface is the mouse. ?
12, maybe there is something wrong with the motherboard itself. You can check whether the battery circuit of the motherboard is broken or whether a capacitor is blown. If so, weld and replace it yourself or ask a computer maintenance person to weld and replace a capacitor with the same specification for you. If the motherboard is broken, you have to buy a new one and install it.
13, the chassis is not clean. The CPU fan is too dusty to work normally, resulting in the CPU temperature being too high. Clean the dust on the inner wall of the chassis, CPU fan, graphics card fan and motherboard with a brush and a hair dryer.
