My mouse cursor continues moving normally, but the left click—and sometimes the right click—randomly stops responding. At the same time, browsers and other applications occasionally act as if the Back command is being pressed. Opening Task Manager with Ctrl+Alt+Delete sometimes restores everything temporarily, and the problem occasionally disappears on its own before returning.
I tested a second mouse that works properly elsewhere, but it had the same problem. I also formatted the PC, yet the issue was still present on the initial Windows setup screen, so it does not seem to be caused by Windows or a particular application. The only major change was moving the computer to a new location.
My system runs Windows 11 with a Redragon M908 mouse, a 4070 Super, 2×16 GB DDR4 RAM, and a 2 TB NVMe SSD. The mouse, keyboard, microphone, and webcam are connected by USB. What hardware or connection issues should I troubleshoot?

One possibility is a failing click switch inside the original mouse. You can open it, clean the switch with isopropyl alcohol, and gently work the button to clear dust or debris, but that is usually only a temporary repair. Replacing the switch requires soldering. However, since a second known-good mouse behaves the same way, replacing or repairing the mouse probably will not solve the underlying problem.
Because the problem continued after formatting and even appeared during the initial setup screen, this points more toward hardware or an input-device issue than a Windows installation problem. Disconnect the keyboard, microphone, webcam, and other USB devices and test with only one mouse connected. Then try different rear motherboard USB ports and inspect the cables for damage. A stuck keyboard key or another input device sending a Back command could explain the browser navigation behavior.
A new mouse would be worth trying for the original click problem, but the second working mouse already showing the same failure suggests the issue is elsewhere—possibly a damaged USB port, cable, hub, or another connected device.
The second mouse having the same symptoms makes a bad mouse switch very unlikely. I would focus on the keyboard, USB connections, and other hardware connected since the move instead.
