Help! system doesn't power on

[zhuhangm]

I was building my system last night, when I had almost everything plugged in except for the RAM and V-card, I tried to power on, but it didn't work. There's totally no reaction when I pressed the power on button. Do I have to have Ram and vcard plugged in in order to get the power on?
I'm using epox 8dra+, antec amg1080 plus,
well there's one thing I'm worrying about which is that probably I cracked the CPU core when I was installing the heatsink...
Any thoughts?
Thanks

I would install the ram. Do you have the power switch plugged in correctly on the motherboard? If it's in the wrong place nothing will happen when you press the switch. Powersupply turned on? Some have a switch on back that has to be on some don't have it. Even if the cpu wasn't working it should still power up.
