It has nothing to do with the motherboard! I have tried in X79, B85, Z87 and even virtual machines! In addition, both WIN7 and WINSERVER 2008R2 systems have been patched! If you don't connect to the Internet, everything will be OK! The OSD display is also very instant. Once connected, it will get stuck! Many of my servers have this problem! As a result, it is impossible to check the number of days the machine has been running. However, on systems with WIN10 cores such as SERVER 2022, everything seems to be normal!
