D1 post code is a i/o initialization code. Check your keyboard, and any other devices plugged into the motherboard. If you have a spare keyboard try that as well.

Ok, I figured it out. I remembered that when I pulled the Athlon out that my screwdriver touched the board. It was light so I didn't think about it. Anyway, I pulled to board out and looked at the area with a magnifying glass and saw little metal particles--might have been carried from the screwdriver. I cleaned them away carefully, reinstalled everything, including the new Phenom and everything booted up just fine. Whew!

Thanks for the tips Shadow. I found out the same thing about the D1 code too, but solved the problem. It was a different issue. I repped you anyway because it was useful info and appreciate you trying and backing up the power needs.

I have a 850W with quad 12V/20A rails! Quad 12V@20A is actually better being that it's more safe. One just has to make sure that they don't overload each rail which is simple.

P.S. I have:
MSI 790FX-GD70
2x 120mm @ 3K Rpm
4x 80mm @2k-3k,
1x Water cooling system
1x MSI 4870
1x PII x4 810 @ 3775MHz (300x 12.5)
1x 4gb (2x2gb) of OCZ Flex EX in WC loop
1x OCZ Vertex 32BG SSD SataII
1x WD 250Gb SataII HDD

Quad/dual/single, whatever. As long as the psu is a quality built unit, has enough power for your needs, and a little headroom to spare, how many rails aren't really important. I have way more power than I need right now. I was running my rig on a 400w Enarmax psu for 2 months before I upgraded to the 650w Corsair. I only upgraded because I plan on buying a 5000 series gpu this fall and I wanted to be prepared for whatever came out.

Yeah same thing here. I know My PSU is (dare I say it) overkill, but I want it that way. They are more efficient, last longer, and give you head room.

I realize that I'm pretty close to bumping up to the limit of my PSU if I'm running 100% and 100% GPU. I didn't think it would be so underpowered that it would not boot, tho. Using a kill-a-watt, my machine idles at 200 watts and maxes at 400 watts and that's with the GPU OC'ed to 1GHz and the 955 OC'ed to 3.8GHz. I take out the OCs and it drops about 50 watts. So if I decide to keep it OC'ed, I don't think there is enough headroom on my machine and I'll get a bigger PSU. Without the OCs, it should be fine. Also, the air coming out of the PSU is cool. The GPU puts out a lot more heat.

I fried my mobo once because of the weak PSU so now I'm always trying to have little bit more power than I need.

What your psu draws from the wall and how much power your system is using are two different things. Remember that at best an typical 80+ certified psu is only around 82-83% efficient. 400w at the wall are about 320w so the psu isn't on the verge of a meltdown.
