Anonymous users2024-02-03The hardware with the reason for the black screen is the power supply.
Memory. Graphics.
Mainboard. cpu
Other packages have a data cable to connect to the display.
The VGA interface is crooked, the motherboard capacitor bursts, the memory is damaged, the gold finger is oxidized, and the slot has dust and dirt.
The graphics card is damaged, the gold finger is oxidized, the slot has dust, dirt, random black screen, caused by software, or there is a problem with the hardware! ~
Detailed inspection method: Preparation before inspection Clean the graphics card, memory, and slot dust Check the CPU slot for dust or dirt! Use the eraser to check the gold finger of the memory and graphics card!
Replace the slots in the memory! Check the capacitors of the motherboard for bursting protrusions or yellow liquid! Check whether the graphics card interface is crooked or that there are foreign objects that cause poor contact!
Check the monitor's interface at the same time! After the check-out!
Step-by-step inspection and troubleshooting with the minimal system method! Minimal system method is connected to motherboard + CPU + CPU fan + memory + graphics card + power supply + monitor! I unplug the thread that is not related to the minimum system method! Press the power button with a screwdriver to power on
Start checking! After pressing the power button to turn on the CPU, the fan can run the instructions, there is no problem with the power supply, you can replace the new memory, try it, most of the black screen right memory is caused by more, followed by the graphics card, and then the motherboard.
Finally, there is the CPU
If that's all right, then you can gradually add the hard drive and then add the optical drive.
Generally, the black screen of boot is viewed with the motherboard test card**It is very convenient to know that there is a problem in that position There is a special black screen That is, the black screen after entering the windos window Press the numlock key on the keyboard to press the light It means that the screen refresh rate is too high Enter the safe mode and load the graphics card and then enter OK!
That's all for most of the problems caused by a black screen!
Boot and press F1 to indicate that your BIOS battery is dead
Let's get a new one.

Anonymous users2024-02-021. The reason why the laptop boots up with a black screen.
There are many reasons for a laptop black screen, and the common reasons for a black screen are:
1. Poor contact of the display data line;
2. Poor contact of the graphics card or;
3. Poor CPU contact and overheating;
4. Poor contact of memory modules;
5. Poor power supply performance;
6. The machine is infected with CIH virus, and the BIOS is destructively refreshed
2. How to fix the black screen of the laptop.
1. The boot display screen is black, only the indicator light is on, and the host does not have any reaction. I can't feel the fan spinning behind my hand behind the main unit. None of the voltages are measured. Remove it and find that the power adjustment tube is broken, and replace it with normal.
2. The power supply and CPU fan are normal, but the screen has no reflection, and there is no self-test sound. This machine adopts SLOT1 structure, the CPU is easy to contact poorly, and it is sent to the after-sales service for inspection and maintenance.
3. Do not self-check when you turn on the machine, and check that the power supply is normal. Using the minimal system method, the machine can start normally when the optical drive is unplugged. Then install the fault recurrence. It means that there is a problem with the optical drive, and the machine cannot be started. It should be sent to the after-sales service immediately for disposal.

Anonymous users2024-01-29What to do if the computer starts up with a black screen.
There is a startup item with multiple startups, or there are system items to start or service items to start, you can take a look, according to 360 and other prompts, turn off the ones that should be closed, basically it's OK, and then the slow startup of the computer is not all the problem of startup items, and it is also possible that the system files are large and many, and most of them are left behind when you install or delete the program, and it will slow down when it is actually long!
Unplug the memory and try the gold finger with an eraser. Then install it. It's OK to boot up.
Start Menu - Run - Enter msconfig Enter.
Put ** in the boot bar insideJust remove the tick in front of the dll. >>>More
An error occurred in modifying the BIOS settings.
02.If it is the boot data of the magnetic region of track 0 of the hard disk, it is incorrect. If it is a hardware failure, use the backup component to cross-check by itself. >>>More
Is it always automatic repair when booting up? And you can start the system after repairing, but there will be automatic repair when you turn it on again after shutting it down? If this is the case, it means that your hard disk is broken, and it is not serious now, take it to the repair point to scan the hard disk, and repair the hard disk track; Don't wait for this every time.,This happened to me before.,In the end, even the automatic repair can't make win7 start normally.,Finally, I changed the hard disk.。
