I bought the Razer Deathadder V3 (Wired) mouse in the month of December 2025, and since the start, I’m facing random disconnects when my PC starts. I have a high-end PC (AMD Ryzen 7800 X3D CPU & AMD RX 7900 XTX GPU), so I’m pretty sure I’m not lacking performance of any kind. Taking about the symptoms, the mouse frequently connects and disconnects when the PC starts, and this starts happening when I start moving the mouse; after a while it stabilises. The same thing starts happening as soon as I jump in a Deathmatch in CS2. The moment I do a hard swipe, the mouse becomes unresponsive, and after several disconnect and connects, the mouse becomes responsive again. The weird thing is, after 2-3 connects and disconnects, the mouse becomes stable in CS2 as well. So, I’m not certain whether it’s a hardware or software fault.
The solutions that I have tried until now:
- Reinstalled Razer Synapse 4 completely after uninstalling the previous one.
- I have done this in the Windows power plan: USB settings → USB selective suspend → Disable
- Disabled this option “Allow the computer to turn off this device to save power” in Universal Serial Bus controllers & USB Root Hub entries.
If someone has solutions, kindly let me know.
