If you think its the PSU; take it out of the rig, hold it upside down, prop something to prevent the fan from spinning, and blow some compressed air into it. See if anything falls out or moves around.
When I have my steelseries sensei frost blue plugged into the usb 3.0 port it works fine and all but when i go to shut down my pc it turns off for a second then turns on and stays on the entire day or until i unplug it and plug it back in and if i dont unplug it and plug it back in and turn my computer on the mouse turns off and doesnt work and when i put it into the usb 2.0 it turns off like it should when i shut down my pc and turns on when i turn my pc on but the mouse just moves so choppy and laggy so i have to have it plugged into the usb 3.0 so i was wondering if there was a way to to fix this
