Mouse and keyboard stop working until shutdown

Hello everyone, this problem had started for me only about 1 or 2 weeks ago, and is rather annoying. What happens is that randomly while using the mouse, it would freeze up and I would hear the "Device Disconnect" sound, and a second later the mouse would work again. This happens absolutely randomly, and after a bunch of times, both the keyboard and the mouse completely stops working. They are both connected to the USB ports on the motherboard at the back of the computer, and unplugging and replugging does not make them work again. The only solution to get the mouse and keyboard working again [temporarily], is to restart the PC using the main power button. When they stop working, the numlock light is still lit on the keyboard, but the keyboard does not respond, and I have a small indicator light on my laser mouse that just starts blinking, when it normally has never done that. Everything else is still working, such as any music playing, and the internet. And that is why I am posting, so that perhaps someone could find a solution.

Thank you, but i found the answer, it was totally becaus the mouse, now i have another mouse and 0 disconnects for 24 h
