Motherboard not posting

[Penny5837]

Just got a new board because my friend gave it to me after he wiped the bios. I bout another chip, and I can't get it to boot. He also left out the CPU retention plate, but I tightened my cooler extra hard. I press the power button, and fans spin up, and then turn off. I've tried clearing cmos, and if I spam that, it will continue to spin fans, but no video will output. I don't think RAM is the problem either, because I've tried every slot/combo of slots. Do you guys think I got a faultly bios chip, or is it something else, please help me. I'm pulling my hair out and I'd like to get my system to boot. I've already posted one topic, but I didn't get any usefull information from it. I hope this post will be different.

It seemed to turn on fine when I took the cooler off and only applied pressure with my finger. I think I need to get the retention plate.
