Ok....
I did this myself, and I can't believe I was this stupid, but nethertheless here 'goes.
I had bought a new mobo, and an tbird 1.4, and a sk6 heatsink. well when I installed the mobo into my case, I didn't remove the extra screw mount from my old motherboard. So when I switched it on, nothing happened, and I smelled smoke...So I called the company that I bought it from, and continued to tell them that they sent me a dead chip...
it gets better.
So I sent the board, and chip back, they test it, and it was indeed dead, so they send me a new chip already in the mobo, pretested it and all. I installed it again, and same thing happened!!!! So now I freak, bring it to a company I used to work for, and asked him to sell me a chip, and install it for me. he agrees, and before I go, I put the mobo back in, and I notice one of the mounts in the case, had no screw hole in front of it, and so I remove it. Regardless, they power it up, it works perfectly fine. Dumbass That I AM!!!
