1. Press F8 to press F8 to get the advanced option to appear in the release of the power, and select "The latest correct configuration" Enter to repair.
2. The simple way is to use the system's built-in system to restore to repair when you don't have this failure (or restore the system with restoration software).

Anonymous users2024-01-31Summary. There are many possible failures.
If the motherboard is not connected to speak, it is possible that the memory and graphics card are loose.
It is also possible that the power output is undervoltage, the north and south bridges of the motherboard are damaged, the CPU is damaged, the CPU is not powered on, etc.
When the computer is turned on, the power indicator lights on, but the screen does not show anything, and there is a chirp from the case speakers.
There are many possible faults, if the motherboard is not connected to the speak, there may be loose memory, graphics card, power output is undervoltage, motherboard north and south bridge damage, CPU damage, CPU is not powered on, etc.
Analysis: If the host indicator light is on or off, the screen is not powered on (the power indicator is not on), or the screen is powered on but there is no signal or "no sighal" is displayed, the former means that the power is not on or the connection is poor, and the latter is generally the memory module is not in contact. Recommendations:
1.If the monitor is powered on but no signal is displayed, turn off the power and turn on the case, plug in and unplug the memory module again, and wipe the gold finger with an eraser (the back of the thumb fingernail is also fine) in one direction, and then turn it on after installation. If you can't do it, then it's simpler:
You can kick the chassis with one foot (pay attention to the location: the front of the shell on the left and right sides of the chassis that does not have an interface at the back). If it's a notebook, you can't kick it, but it's the same for other operations.
2.If the above operations do not work, turn off the power and turn on the chassis, reinsert the graphics card, and plug in the data cable between the monitor and the graphics card. 3.
If the monitor is not powered on (the indicator light is not on), look at the back of the monitor, plug the power cord that connects to the monitor upwards, and check that the other end of the power cord is powered on to the outlet.
Repair it with Super Bunny's IE repair tool.,If it doesn't work.,Reinstall IE If you can, call a friend who will help me in this area I'm limited in ability.,I hope you're so good!!
It's actually very simple, it's not a problem at all, just wait a little longer when you turn on the next time you turn it on. If you are automatically connected at boot, it is recommended to cancel the automatic connection, which can basically be solved. Because my family does this a lot, and now it's done.
I don't know if the landlord asks about the hard disk damage is hardware or software, the software damage will generally occur, file loss, capacity size display error, partition loss, program operation is not normal and other phenomena. If the hardware is on, there is generally an abnormal sound of the active motor of the hard disk, an abnormal sound of the servo motor of the magnetic head, a power-on and boot display that the hard disk or the hard disk partition with boot data cannot be found, abnormal entry into the system, abnormal file reading and writing, etc. Generally speaking, the hard disk is a relatively durable part, and the probability of physical damage to the hardware is not high, but this is a delicate thing, and the distance of the head suspended on the platter is calculated in microns, so it is particularly afraid of vibration, and the violent vibration will cause the head to hit the platter, resulting in disk data loss and physical damage. >>>More
Maybe it's a black python.
