Christenson,

That's an interesting point. In preparation for the brain surgery, I've been watching YouTube videos on how to replace your CPU and fan, and most of the operators aren't using ESD protection.

In my own tinkerings I've never used a wrist strap or anything like that, but I have always been careful to touch other metal right before diving into the PC chassis, just in case.

You should be OK as long as you touch the case's metal frame before touching any of the circuits. That, and if you're building the computer on a carpeted floor (as I have done in the past), don't set the components directly on the carpet, but rather on top of the antistatic bags they came in.

Now I have an anti-static wrist strap to use in such endeavors, but one is definitely not strictly necessary to build a computer. The risk of harming the components is a little higher, but can be minimized if you take the appropriate precautions.

I'm not entirely sure how much an anti-static wrist strap costs (I got mine as a Christmas gift) but I imagine you can get one for pretty cheap from just about any hardware store. It would probably be a wise investment if you can get one, since it will surely be cheaper than the cost of replacing a fried mobo or the like.

The motherboard is also colour coded and should also say what each of the pins do in REALLY small writing, but it's written bigger in the motherboard manual.

Just what I needed to know!

have removed RAM, checked for 12V on the CPU power connector.

Wow, where'd I get that avatar? Something for extra compute progress? E-mail from Asrock says pull Mobo out of case, but includes bootable OS HD and a separate PCI video card in the steps and leave in a memory stick. Bedtime, I won't make more progress until tomorrow.

The avatars are a gift from ~~Xyzzy~~ The Gerbils (well, now the Gerbils are dead and replaced by a Snake--but they're still here in spirit

, see here for the full story). They usually are bestowed upon someone when they start posting enough to graduate from "total forum newbie" to "someone who might be identifiable by screen name to someone who follows the forum regularly". I actually got mine within just a few posts...seems you have to post a little bit more than that to get an avatar nowadays (the Snake is still learning the ropes of creative avatar selection).

Christenson · 2011-01-28, 05:28

I prefer my avatars from Xyzzy...it sounds better...now to find out if the video card or the HD was required. Am wondering about some cheap parts to help bring up the box until we figure out which one is dead or what we are missing.

mdettweiler,

I'm still getting my "new postings" notices from The Gerbils. I didn't know they had passed away. Are they communicating from Beyond?

Xyzzy did say that they had a psychic connection...

Something like that...see here.

Out of case, ATX power connectors (24 pin and 12V CPU power) all pins read good, except possibly -12V nom at -11.05V. Pwr good signal at +5V. CPU, CPU fan connected, CMOS cleared more carefully...still no beeps...not out of the original speaker (which works, though not loud, when fed 5V CMOS from a cheap sig gen at 1KHz), not out of a cheap speaker from Radio shack..but now it powers up the fan with the "on" command.

Wondering if the next step is a cheap AM3 socket CPU at $35?? Am thinking the Mobo is dead..I'm having enough trouble with the other desktop that I want a known good optical drive, can't get that locally since it's still parallel ATA.

Since you're not getting any beeps from it, let alone some screen output, it does indeed sound very much like the mobo took "a crap in its quantum pants."

However, this is what RMAs are for! You can send it back and get another one, hopefully one that works this time. Since the motherboard you have is currently out of stock, you can probably ask for a similarly priced replacement model. Of course, Newegg are a business, so if you wanted a pricier model I'm sure they'd let you pay the difference for an upgrade if you so wished.
