There are many reasons to play game cards. I suggest cleaning them up. There are many reasons for computer cards. First, eliminate hardware problems and network reasons. Check your network first, and test the network speed with Tencent Computer Manager's toolbox to see if the network speed is good. Secondly, you can open the chassis and clean up the dust on the host, including the memory on the fan, because too much dust and poor heat dissipation will also make the computer run too slowly. Thirdly, it may be that there is too much computer garbage and the space is temporarily occupied, which leads to the computer card. You can use the garbage cleaning function of Tencent Computer Manager to clean up the garbage. Tencent Computer Manager cleans up the garbage once and scans it again, that is, stop some unnecessary software running in the background, turn on Tencent Computer Manager to speed up optimization and optimize some startup software you don't need. Finally, it may be that your computer is too slow, because there is a virus or Trojan horse in the computer, you can turn on Tencent Computer Manager antivir's killing engine to scan the virus.
