Ask for advice! My computer won t turn on!

I'll come to your questions. Hope it helps.

It should be a poor contact between the hardware, or a hardware failure, and the related hardware involves memory, graphics card, CPU, motherboard, power supply, etc.

The boot of the computer must first be powered by the power supply, then guided by the motherboard's BIOS self-test, and then through the CPU, memory, graphics card, etc. This process is reflected on the screen called self-test, first through the graphics card BIOS information, then the motherboard information, then the memory, hard disk, optical drive, etc. If something goes wrong with any of these steps, the computer won't boot up properly, or even go black.

First, make sure that the external and internal connections are connected smoothly. The external connection has a monitor, a host power supply, etc. There is a cable between the host power supply and the host power connector inside (sometimes the contact here is not good).

The more common reasons are: graphics card, memory due to long use, long-term contact with dust in the air, resulting in the oxide layer on the gold finger, resulting in poor contact. In this regard, rub the gold finger back and forth with a moderate amount of alcohol glued to cotton, and insert it back after drying.

In addition, observe whether the CPU is working normally, turn on for about half a minute, and touch the heat sink of the CPU fan with your hand to see if there is a temperature. If there is a temperature, the possibility of CPU failure can be basically ruled out. If there is no temperature, tidy up the socket of the CPU to make sure the contact is in place.

After that, before the temperature, your CPU can be upgraded: (In addition to the above method, there is also a nirvana: use the jumper method to clear the BIOS settings or replace the CMOS battery of the motherboard.)

When all of these methods have been tried and failed, you can take them to the computer city again for maintenance.

You put the bios

Restore the factory default... If it doesn't work again, press and hold shift+f10 to turn the network card on and turn it off.

That's it.

Back to the owner: This sentence means that the disk boot failed, please insert the system disk and confirm.

Instructions that your system cannot boot from the hard disk require you to plug in the system disk to boot.

Solution: Because after you took the battery off the motherboard, the motherboard was discharged, and all the bilos settings were reset to the time when you first bought the computer.

It needs to be set to boot on the hard disk.

1.Start your computer and hold down the Del key until the BIOS setup window appears (usually with a blue background and yellow English text).

2.Select and proceed to the second item, "BIOS."

Setup. Find the item or group that contains the word boot, and find the three items in order: "first", "secend", and "third", which represent "first start", "second startup", and "third startup" respectively. Select "first" and hit enter, select "disk" in the submenu that comes out, then press enter--- press esc to return to the main menu--- press f10 and press enter, the computer will automatically restart to see if it can start.
