Recently, the computer has always been a good card, which master will help me?

Troubleshoot network issues.

The most likely is the virus.

If it had been good before, it was probably poisoned!

First of all, you need to install antivirus software, then update to the latest version, and disinfect the virus!

Then update the system vulnerabilities to make your computer the best it can be!

Don't rush! Be calm, the more anxious you are, the worse you get!

1. Check the CPU and graphics card for heat dissipation, dust removal, oiling, or replace the fan.

Second, the power supply voltage is unstable, the power supply is insufficient, and the power supply with high quality and high power is replaced.

3. Clean up and defragment the disk.

1. In the window of my computer, right-click the drive letter you want to clean up - "Properties" - "Clean Disk" - check the files you want to delete - OK - Yes.

2. Clear the temporary file, start-run-enter %temp%-OK. 3. Clean up the registry and junk files with Optimizer or Super Bunny.

4. Close some startup programs, start-run-msconfig---start, in addition to anti-virus software, input methods can be turned off in general.

5. Delete unused program software.

7. Reduce the burden of memory, do not open too many programs. If you have too many documents open or too many programs running at the same time, you will not have enough memory to run other programs, so you should close the programs and windows you don't use at any time.

4. Upgrade the motherboard, graphics card, and network card drivers.

5. Increase physical memory, replace it with high-quality memory, and set up virtual memory reasonably.

1. To play games, the virtual memory can be set to be larger, the minimum value is multiple of the physical memory, and the maximum value is 2-3 times of the physical memory. No matter how big it is, it takes up too much space on your hard drive.

2. The method of setting virtual memory is: right-click on my computer - Properties - Advanced - Performance Settings - Advanced - Virtual memory change - Select the partition where the virtual memory (page file) is stored in the drive list - Custom size - Set the value in the "Initial Size" and "Maximum", then click the "Settings" button, and finally click the "OK" button to exit.

3. The partition where the virtual memory (page file) is stored must have enough space, and the hard disk resources are insufficient, resulting in insufficient virtual memory.

Take a look with 360 Security Guard to see if there is any malware!

Use Windows Optimizer,Delete the fragments,Tidy up the fragments,If it doesn't work, it's the best way to redo the system,

I've also encountered the same problem, the problem is that there is a problem with the graphics card driver, and the way to deal with it is to install the graphics card driver again!

It's their internet speed problem. It has nothing to do with you.

If there is junk or virus, it is recommended that you take a look at the task manager to see what program is taking up a lot of CPU resources, and then end the process. See if you can.

Clean up the system garbage first, see how much space is left in the C drive, at least not less than 1G, and finally look at the amount of virtual memory, you can increase the virtual memory appropriately.

Let me briefly say: 1. The memory is not plugged in properly, and it is reinserted. 2 hard disks have bad sectors, change. 3. Viruses. 4. Some programs are not compatible! Don't worry, it's not a big deal! Good luck!
