Recently, QQ Internet cafes have been continuously pushing game advertisements in the lower right corner of the client at startup. When clicked, it shows special privilege advertisements. Some Internet cafe owners are quite displeased and even mistook it for advertisements related to diskless solutions like "万象" (Wanxiang) or "无盘" (Diskless). Below is the image: Solution: Delete the following DLL file in the Tencent special privilege client folder on the server: X:\comgame\qqwb_client\cjson.dll   Credit to "易速网维" (YiSu Network Maintenance) for providing the solution.

Today, in the group chat, I saw a friend mentioning that they were getting only around 40 FPS while playing League of Legends (LOL). Such a low frequency is definitely not normal. It can cause performance issues and make any game lag. An abnormal frequency can lead to slow boot times and even though the network is 1G, it may behave like a 100M connection. Opening any program would be extremely slow, and games would experience low FPS, among other problems. Here are some solutions to address this issue: When encountering such a problem, try removing the motherboard battery to discharge and restore default settings, then test again. Update the motherboard BIOS and test. Swap the CPU with a neighboring machine to determine if the issue is with the motherboard or the CPU itself. By performing these troubleshooting steps, your friend may be able to identify the root cause of the low CPU frequency and resolve the performance issues they are facing.
