After getting all my pieces together I decided to try to build my first pc. Followed the guides to a Tee, but when I connect the monitor I get the message "No Video Signal." You can see the LED lit up on the MOBO, hear noise from the HDD, and the fans spin but nothing else. Have checked the connections for the HDD, made sure the 2 PSU inputs are connected (the 4 pin and 24 pin) and tried the memory in different slots, but still no post. Any ideas what else to do, PLEASE????
