After the computer is turned on, there is no notification on the desktop

Give me some reward, I'll tell you.

This happens from time to time:

1: The power supply is damaged, change the power supply of the chassis.

2: Memory is the problem, because the memory is too dusty or caused by poor contact.

3: All kinds of boards are not in good contact, such as graphics card, sound card, network card, etc., remove and wipe the board and install it.

6: The computer case overheats, resulting in the inability to display.

7: The monitor cable is faulty, reconnect or replace the cable.

The display has no display, which means that there is no signal input, one looks at the graphics card, and the other looks at the display.

It's possible that your display doesn't support low resolution.

1) Press F8 immediately after booting or not booting up to press F8 without moving to the advanced option to appear in the release hand, use the up and down keys to select safe mode enter, enter the safe mode and use the software to kill the Trojan, uninstall everything installed before the accident, including the game, restore the system or reinstall the system (if you can enter the safe mode, it means that you have installed something inappropriate, uninstall all the inappropriate things before the accident, and you are hit by the Trojan, use the software to kill the Trojan, if not, restore the system or reinstall.) If you can enter normal mode, you can also do it in normal mode according to the method above).

2) If the above methods can't solve the problem, first soft and then hard, reinstall the operating system, don't install software, patches, drivers, etc., and see if there are still problems with booting? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

Please note: If you restore the system or reinstall it, when installing drivers, patches, software and other things, be sure not to install the things that affect your accident this time, otherwise it will be restored or reinstalled in vain.

3) The above is caused by system problems, and the following is caused by network problems.

1. If it is a problem with the broadband itself, first directly connect to the broadband network cable for testing, and if it is a broadband problem, contact the broadband customer service to solve it.

2. If it is a problem with the router, if it can be used originally, it cannot be used for the time being, my own practice is to disconnect the power supply of the router and plug it in, and I will see. In there is a factory reset, it can be used from the new settings (this is under the premise of the correct physical connection, sometimes caused by the router's slow or failed IP address search, not that the router is broken).

If it can't be solved all the time, it is recommended to call the customer service of the router, they have **** guidance, I encounter a problem that I can't solve by myself, it is very useful to consult the advice they gave, and they will give the correct advice for your settings or operations.

3. If you turn off the wireless switch and turn it on, if it is a wireless connection with software, it is normal for the software to be difficult to use and often have problems, there is no better way, use a router. In addition, it is caused by the network card driver is not or is not suitable, and whether there is a problem with the network cable interface or network cable.

4. If it is caused by system problems, it is recommended to restore the system or reinstall it.
