Mouse and keyboard freeze, and monitor not turning on.
Just built a new system (spec below). About a week after it was built, the keyboard and mouse started to freeze. I would shut it down and my monitor would then stay in stand-by mode and not come on. This tends to happen after half an hour of the computer being turned on. I've cleared CMOS, re-installed all components and nothing seems to work. Not sure if this is my power supply, mobo or ram and i've no spares to test. Any Help would be great.
