I have recently bought components for a new pc and have put them together and then when I went to power on and start setting everything up I was met by... nothing. I got a Rosewill 103A Case with 350W psu, Asrock 775V88 Mobo, 2.8ghz p4 lga775, Geil pc3200 512mbx2 ddr, nec 3520a, sony dvd reader, 80 gb maxtor sata hdd. I have built 1 system, but it was barebones with case and mobo together. I have done everything that I can think of correctly and I am having a hell of a time figuring out what it is that I am missing. When I power the system on I can hear the high pitched sound of a current, but the psu fan doesn't come on and neither does anything else. I took the psu out of another comp and plugged it to my system and it did the same thing, nothing came on, not even the psu fan, but could hear the current. If anyone has any suggestions of something I could be doing wrong, missing, whatever, I would appreciate it, I know its kinda difficult to just guess when you can't even see the system.
