2 mobos killed :( - what to do...

Edit: memory and/or the second sound card appear to be damaged, need assistance with identifing what is damaged. More info 2 posts down. [/edit]

Summary: I think a bad sound card shorted out my mobo/cmos/bios/something...

About a month ago I was trying to connect my AIW Radeon's internal audio out to my SB Live's internal tv in connector, without success, in doing so, I think I created a short on the sound card.

When trying to boot my system, about 50% of the time it refused to even post, when it did, windows would boot fine and run for up to 30 minutes without any problems (sound and video card both working), but then I would get either a system hang, or a reboot, which failed to post.

I then tried swapping out the video card or sound card with another, assuming one of the two had been somehow damaged when I was working with them...conclusion: sound card was causing the problem...get new sound card.

This worked fine for the last month, until I started having sound card related problems with the new no-name sound card I got to replace it, unable to access the mixer, some programs needing sound stopped working, even though windows was playing system sounds and such, very odd. After no success trying different driver sets, I thought I would try out the sb live card, figuring the worst that could happen was a repeat of previous problems...

Swap in sb live card, windows detects, restarts, windows restarts, blue screening (in XP RC2, almost unheard of to my knowledge, I had been running XP since beta 2 with never such an occurence) and then rebooting, failing to post. I figured this was just verifing my theory that the sb live card was dead, but figured it couldn't hurt to try...on the next reboot I got an error saying the CMOS had been reset (which it had), so I reset everything in cmos, rebooted, and haven't been able to get a post since...

Did this bad card kill my board, or could there be another problem I'm missing? (new cmos battery, anything else...?)
 
Ensure that your PSU is okay, it could be under powered or faulty.
Try different RAM or if you have more than one stick of RAM, try running the machine with only one module installed - may be one is damaged.
Try running the machine in minimal configuration - with no sound card, may be the old sound card is faulty and the new generic card has crappy drivers/incompatabilities.

If these check out okay, I'd say theres a very good chance its your motherboard at fault


 
Crap, running on a minimal install didn't help, so I was transfering over the ram and new/generic sound card into a lesser machine while I wait for a new mobo to arrive, unfortunately, doing this seems to have ruined this system too. I am really concerned now.

Why would the ram chips and/or sound card that hadn't caused any problems in the past kill another working system? Would the original short have tainted one or all of these components as well? I'm also concerned about the remaining components in the original system, (2 40 gig hard drives, dvd, cdrw, t-bird 1 gig, AIW Radeon, network), could one or some of these also have problems now? I would have thought the short would have stopped in the mobo.

The last thing I need is to kill another board (or two) weeding out tainted components.

Does anyone have any experience with this type of issue and/or have any suggestions of how to go about dealing with this?
