Sorry if this is in the wrong place but I am having a bit of a problem. Just put together a new box and I can get it to turn on but there is nothing on screen. The screen actually goes into power save mode like it doesnt even know the computer is on. This is only my second build. Everything in the box turns on but the keyboard and mouse dont light up. specs are-phenom 2 940, gigabyte ma790gp, corsair tx650w, 4gb g-skill 1066, 9800gt, wd caviar 640gb, antec 900. Any help at all would be great.
