I am building my 2nd puter, before I tidy everything up I wanted to make sure that, it would power up before tiding up the case anyway. I have memory,cpu, and video card and monitor in place. I am using 4G Corsair ram, EVGA 7900GS, green power light on board comes on, red cpu led is on, fans are on and so is cpu fan. Anyway I am going DVI to VGA to monitor(2nd DVI connector doesnt fit the Samsung monitor). Anyway on power up I am not getting a Bios screen and my monitor is saying to connect cable even though it is connected. Also there is a white 1X4 plug that looks like a case fan plug on the board by the cpu, do I have to have power hooked to it also? I am using a Corsair HX620 power supply. If anyone would help I would really appreciate it.
