I can't get it right- does this sound like a dead CPU?

I want to give up so bad. I want to just chuck this system out the window because I've exhausted both my money and time trying to fix this. School starts in 2 weeks, and I will have 0 time to do anything with my computer. If you think this sounds like anything you've heard of, please tell me. I'm frustrated beyond belief.

I built my system in August 2010 with the help of a friend (I'm now in a completely different city).

OLD MOBO: Gigabyte X58A-UD3R Mobo (

CPU: i7-930 (

PSU: Corsair TX850 (,

Graphics Card: PNY Geforce GTX 470 (

RAM: Muskin Redline 6 GB-3x2 (

HAF X case/ Xigmatek Dark Knight Heat sink.

In February, I started having weird power issues. My computer would shut down (anywhere from 1 time a week to 3 times a day_, and I couldn't turn it on without repeatedly disconnecting and reconnecting (up to 10 times) my 24 pin connector. I posted here and noone could really isolate the problem: PSU or mobo? I was finishing up my thesis at the time, so I didn't find the time to try and fix it. In early May, I finally took the time to call Gigabyte, hoping they had heard of it. After a good deal of poor customer support, I decided I would RMA, sell the RMA'd mobo, and then purchase a new motherboard. In the mean-time, I called Corsair. They suggested that it could be my PSU having issues with power. I RMA'd this and borrowed my brother's Corsair TX750V2 (he is in Hawaii at graduate school now).

I decided to purchase a new motherboard:

New motherboard: ASUS Rampage III Formula (

I followed instructions and watched a few videos on the proper way to replace my motherboard. I used a xylene based cleaner and then isopropyl alcohol, once again following instructions. I then used Arctic Silver 5 as my thermal paste.

I built. I plugged in the 750W PSU, and turned it on. Before even turning on my computer, the case LEDs and case fans turned on. Weird, so I powered up. The heatsink fan began twitching. No post. No beep codes.

I changed back to my old PSU. Same problem. I tried using only 1 stick of RAM. Same problem. I reseated my CPU. Same problem. I tried to breadbox it (boot up with minimal components). Same problem.

I posted on reddit, and I posted here. I had no idea why my case was lighting up without powering up my system. Then when I had hit power, the CPU fan twitch was very odd.

After trying more solutions, I decided to RMA my motherboard. I just received my new motherboard, so I decided to try again.

Same problem. I don't know what to do. I'm almost broke.

Did I screw up my CPU when I replaced my motherboard? How can I tell? Please.

It's hard to damage the newer Intel cpus. More likely you will damage the board pins under the cpu. I think it's time you took your pc into a shop or posted a request on craigslist for an unemployed computer tech. Some of them only charge $25 in my area to check out a pc, and they may come to your home. Too bad you don't live near me in austin. I would only charge for the gas.

Are you sure you have all the case to motherboard connections installed correctly? You could be grounding out and there by causing some kind of short.

Lots of people have had simular problems with that board only to RMA it and get another bad board which sucks because that leaves you not know which is the problem.

I suspect motherbd.
