Hi all, I just got my new computer this week and It's finally built. I'm able to get on the internet but I have a serious issue. My computer will not boot up if I have my mouse, keyboard, and headset plugged in (logitech mx510, logitech elite, sennheiser pc 150.) The computer will just hang on the Lan Party nF4 screen which is very annoying. I don't think it's underpowered, a 500watt ultra power supply. Full system specs are in my signature. Thanks for your help. BTW, I would go into the BIOS. But I can't since I can't have my keyboard plugged in in-time to hit delete.
