new mobo problems

I just installed a new motherboard, exact same model as the one I was using before. I got everything hooked up and hit the power button and nothing shows up on the screen. All the fans and lights come on but there is no beep and nothing comes up on the screen. No other hardware has been changed. I have tried it without ram installed and I get a series of beeps so I know the mobo speaker works. I have also tried different sticks in different slots and no luck

I have cleared the cmos by touching the pins together with the PSU unplugged. Should that be done with the psu unplugged or not? I have not taking the battery out. Would that help any?

I would put the other mobo back in but I am afraid I have damaged that mobo by removing the backplate for the cpu cooler. I put a little heat to it with a hair dryer and it turned the mobo a green color around that area and I still had to put quite a bit of pressure on it to get it off. So I could of dug into the mobo a little too. It looks okay to the naked eye though.

This is a brand new motherboard that has been tested out before it was shipped.
 
Because I believe the mobo was causing a couple of problems. One was the display driver error. While playing a game, it would randomly crash with the display driver has quit working and has recovered. For the life of me, I could not figure out what was causing it. I even RMA'd the video card and still the same thing. Then out of the blue I did not receive that message. I have no idea what I did to make it stop. I just reinstalled Windows 7 and now it is back.

I am also having problems with the hard drives. I have 2 WD Caviar Black 500gb drives. My transfer speeds were real slow between the two drives. Every once in a while, the computer would not boot up and all I had to do was switch the hard drive sata cable to a different sata connector on the mobo. I also RMA'd the drives and still the same thing. Right now one hard drive is showing a faulty temp. It is reading around 45c where as before it would be in the 20's. A couple of times, it was showing around 70c and it did not fell that hot to the touch. Sometimes if I switch it around on the mobo, it would show the correct temp. I guess it is possible that I could receive 4 bad hard drives but I highly doubt that.

Both of these problems lead back to the mobo. I even RMA'd the mobo and they said nothing was wrong with it. So they sent it back to me. Of course they could have just installed it in a system, loaded up Windows and everything ran fine and said it was ok. They may not have put it under stress.

I originally thought it was the PSU so I bought a new Corsair 850 watt and did not help. I tested the memory and received no errors. I have tried different sata cables. Really besides the CPU, there is nothing else it can be. And I don't see the CPU being bad.

One reason I bought the same mobo is because mobo's confuse the crap out of me. I have no idea which one would be a good one.
 
I had thought that it was the psu unit myself m8 and to honest if it was, once it has caused the problem a new psu isnt going to help at all as the damage has already been done
other than that all i can suggest is to reseat the ram and ensure that new thermal paste is fitted and ensure the heatsink is fitted correctly but generally no beep on start up means either a short(ensure m/b fitted correctly) no power, or a bad CPU/MB
 
The PSU was the first thing I replaced. Just about every piece of hardware has either been tested or replaced.
