System won't boot

I just built my new system and I don't know what's wrong with it. It turns on, the motherboard light goes on, and everything goes on, after about 3-5 seconds it starts making a moderately high beeping. The monitor is on, a signal is sent, but there's no bios. This isn't my first computer. I've double checked and everything is plugged in. Memory and VGA are all they way in and vga has it's 6-pin in. I would try another vga or use onboard but I only have one and there's no on-board to plus the monitor to dvi or vga cable. I don't know what could be wrong. Only things I can think of are: I used my old hdd from my other computer and tried to boot it up from that, could it be there, since it had different mobo drivers? (I didn't think it would be that). Also, when the cpu was locked, I accidently pulled too hard on the cpu cooler when installing it and the cpu came out. How bad is it for the cpu to come out when it's locked? Could that be the problem? Thirdly, I never put jumpers on the hdd or dvd-rw, but I thought it should automatically try both until it prompts me to boot from my windows 7 dvd from my dvd-rw. Anyways if anyone could help that would be great. Thanks
