Hi. After plugging my new mouse (as above) the time of loading my system (before Windows) had increased a lot. Basicly I have three stages before Windows starts:
1. black screen with sign (i think) B4 changed to 98 at bottom right side of screen for about 2 seconds
2. screen with detected disks, ram and some info of MoBo, about 2 second
3. last is MSI logo which lasts for about 1 second and then Windows

After plugging this mouse the first screen lasts for about 10 seconds what is really annoying. What's the point of saving some Windows loading seconds wiht SSD when your MoBo loads for 15seconds.

PLease help.

Welcome Elkey,

Are you plugging this into the USB headers directly on the motherboard?
Have you tried other usb ports?
Have you tried the mouse on another computer to see if it does the same thing?
Do you have an addon card for USB ports that you could try?

I'm not sure what the first thing you are seeing is. Do you have a picture of it?
