So I bought parts for a new computer from tigerdirect. I went to hook everything up, and when I went to hit the power switch nothing happened. I tried many combinations on the motherboard and realized that everything was hooked up correctly. I took the motherboard back because I thought it was dead, and still nothing. I took back my power supply and got a new one, stil nothing happend when I went to turn it on. I took everything out of the case and assembled it on my floor, boom- it turned on. So i put everything back in the case and it wouldn't power up. WTF is the deal. My case is shorting something out!! Has anyone ever had this problem??
