Mobo replacements and the pits of Hell.

Well, I enjoy tinkering with stuff and putting things together, but there is the unfortunate problem I mentioned earlier. At least for me, it doesn't seem to matter how carefully I do everything, something ends up not working. When I did a MOBO replacement several years ago I ended up with a system that wouldn't power up at all. A friend with more skill was able to fix the problem by disassembling a plug, separating its connectors, and basically fitting them one-by-one into the connectors.

My failure at replacing my motherboard, as well as getting my old motherboard working again, has given me new insight on these things. I approached the problem as "I'm Rowdy Rob, king of the universe. How hard could it be? No mere mortal challenge is too hard for me to figure out" as I approached the motherboard/cpu swap-out. A day later, tail between my legs, I was crushed into acceptance that I was less than a mere mortal... :-)

I don't like to lose, however. I did more research, and it appears that I did most everything right. However, the SERIOUS crux of the problem for me, as well as (I suspect) most beginning motherboard tinkerers, are all the little "two-prong" connectors that go from the computer case to the motherboard. These little connectors attach to the case's power switch, LED's (hard drive and power LEDs), and case fans. Most documentation appears to give little information as to how these connectors are to attach to the motherboard. Apparently, most motherboards have little "texts" on the circuit board that tell you where, specifically, these connectors attach to on their "grid" of connector prongs, but they are generally misaligned or don't make it REALLY clear how these connectors go. If you don't properly connect your case's "power switch" to the motherboard, your computer won't power up!!!! That's what happened to me, and it scared the life out of me when my newly-configured PC wouldn't power up!

The "case-to-motherboard" two-prong connectors seem to be the key. After failing to reconnect my old motherboard correctly, I went to the bookstore and read some info out of some of the books there. I came back home, reconnected these connectors, and my machine powered up again!

It gave me more confidence to try again with the new motherboard this weekend(?).

By the way, both my PC's (not counting my laptop) are kit-bashed, but not by me. My good friend, who is an uber-geek professionally, custom-built these machines specifically for me. On the one hand, they have been great, great machines, but on the other, it made me reluctant to go out and "upgrade" to a Dell or Alienware or something, simply because I felt that it would insult my friend. Well, he's the one who recommended my upgrades now; I wish he would have installed them for me. But I wouldn't have learned anything, or have DEFEATED anything, if he did.
