Restart the computer, press f8 all the time, and enter the safe mode Advanced Startup Options Last Correct Configuration to see if it works. If it doesn't work, select "Safe Mode" Normal Startup on the interface just now, and then go to the desktop to see if it works. Use software anti-virus. According to your preference, the editor uses 360 to introduce.
Open 360 Security Guard and select the one on the right. More 360 System First Aid Kit, System Repair, All Selection, Immediate Repair, Network Repair, and start repairing.
Click: After the "Start First Aid" is over and the computer is restarted, open 360 and click "File Recovery". Select all to delete the file completely!
If not, unplug the video card and memory module, wipe with an eraser, and then use a brush to clean the dust and fan in the socket, and replace the memory socket! Be careful when removing the computer. Remember the location of the removed parts
If it still doesn't work, you need to "one click restore" or "reinstall the system"! (But you must have backed up the system before!)
The last method is to select the "Computer Repair" status, and "Start Repair" is under automatic repair. (Usually this repair takes a long time, and you don't need to worry about it, just let it repair itself.)
Maybe it's because of the driver, then download "Drive Life" and upgrade the graphics card driver!
