I have a slight problem. My previous build wouldn't boot.I had trouble installing the seidon 120v liquid cooling heatsink. Anyway, while installing the heatsink I lost contact between the two surfaces with thermal paste several times (very frustrating). Basically, I was struggling. I had my mobo on my lap trying to get it right. When everything was installed the computer would not start. No power. So I automatically assumed it was the motherboard.
So, I bought a new motherboard and the same issue except the fans are powered on. Do you think I messed up my cpu?

How could have messed up my cpu, I thought it was the most durable part. I used rubbing alcohol to help remove thermal paste each time. Or is my new motherboard DOA? Please give insight.

I was installing my new Seidon 120V to lower cpu temps. If I had known the hassles that came with it in advance, I would have never bought it. Any way, I kept loosing contact between the two surfaces (cpu and heatsink). So I kept applying thermal and then taking it back off if I lost contact to avoid air gaps, using isopropyl alcohol. I probably, realistically did this step 10 times before I got the heatsink on the cpu. Not to mention, I was so excited when I got my new heatsink, I did not follow the directions properly, so therefore used the wrong screws on the back panel (plate that goes behind mobo) so the male screws were too short and would not reach the female screws on top of the mobo which led me to loosing contact between the two surfaces several times. Now, during the whole process, I started getting angry and kept applying more force until I finally got the mobo on my lap (I did not care about static at this point) and then finally realized it was the wrong screws. When I had finally finished installing the Seidon 120V, my computer would just turn on the fans but not send a signal to the monitor and so in turn I had no bios. Then finally there was also a loose screw in the back of the motherboard which I think "shorted" the mobo because it slighted tapped the motherboard while the fans were running and then just everything shut off, even the fans. From that point on nothing came online. At this point, I thought it was either my mobo or cpu that was dead. I automically assumed it was my mobo becuase of the "short" and I had no subsitute pieces to test out my hypothesis. The odds were in the favor of the mobo because the cpu is typically the most durable. Now my new mobo won't give the monitor an input signal as well so I've concluded that it is most likely my cpu that is dead. I am right?
