Hi there. Since I bought my new mouse and illuminated keyboard, when I use the PC a lot, they have spontaneously been stoping for a period of time and then they work fine. I didn't have this problem before because I had a ps2 keyboard. Now I have USB mouse and keyboard and this happens. I do believe there is a problem with the power management. A friend of mine has the same motherboard and he incurs the same problem. I have a Gigabyte GA-B75M-D3V and here is a printscreen of my bios with the power management tab. What settings should I change?
