Is my motherboard dying?

Haven't ever seen something like this before. . .

About 2 months ago I started having problems with my CD/DVD player in my system. It stopped reading CDs, although it would correctly read DVDs. I swapped in an older DVD ROM I had handy and it worked fine, so I chalked it up to a dying player. I bought a new one from NewEgg and swapped it out and everything seemed to be working fine. Then a few days ago I was copying a new CD onto ITunes and half of the tracks didn't copy. WinXP event monitor said that I was getting errors and warnings from the new player and the link to Microsoft's support page said that the error is usually a result of a problem with a cable. OK, no problem, I have extra EIDE cables hanging around, swap the cable and the problem goes away. Then, not 30 minutes after I swap the DVD's cable I start getting warnings from my data drive, a 250G HD. Again, XP was saying the cable to the device was failing. The drive is SATA, not IDE so I start getting worried. The odds of a SATA cable AND and IDE cable failing at the same time are about nil. I reseated the SATA cable to the disk drive, but no help. I finally moved it to another SATA port on my mobo and the problem seemed to go away. That lasted about 24 hours until tonight. Then the computer simply crashed while I was working. Now it would not restart at all. It would get to the point where asking whether I wanted to boot up in safe mode and load up until vgaoem.fon and hang. A quick run around on google and, lo and behold, when Windows loads incomplete like that it's usually a problem with cable seating. So now the problem appears to be affecting my 70G boot drive. I have not been able to get past this point, swapping cables and positions still will not get XP to boot.

I'm very suspicious of my mobo. Currently I have an Asus P5WD2 Premium (955x). It's the only common denominator that could be why all my drives suddenly seemed to go crazy. But buying a new mobo and hacking apart my computer is not a great option. On the other hand, the alternative isn't too hot either, which is trying to reinstall Windows. That would pretty much trash all my applications. And if it ends up being the mobo then I've just fragged my applications and still need to buy a new mobo.

So I'm looking for opinions. Go mobo or go windows reinstall? Or am I missing another alternative?

No, those are really the only two options, besides an RMA. You should reinstall Windows, though, before asking for an RMA, since that can cause your symptoms. Also, you might consider doing a MBR repair, but if it's the motherboard failing, that won't do you alot of good, except it might allow you to retrieve some of your data. Oh, I'd also try resetting your BIOS. That has fixed more than one problem with drive access, though it's not as likely as the other two options.

Just got off the phone with Asus tech support and they think it's a Southbridge failure as well. They want me to yank the whole mobo and start it on a non-conductive surface. That was the next thing I was going to do, but that's a few hour job with everything I've got in there if I want to do it safely. Just on the off chance that something is shorting out the mobo.

Crap.

I've never heard of a Southbridge failure, although I suppose it could happen.

Looks like I may have gotten off lucky and it was just a short in my motherboard. I must have jostled something when I installed that DVD player. I totally rewired my case, redoing all the tiedowns and also reseated everything except for the CPU. I did have to repair my Windows but at least I was able to get that far once everything was rewired. I have NO idea what was causing the short, as the wiring job was pretty good beforehand, but I must have missed something. Thanks everyone for the advice, hopefully this is the end of the weirdness.

If you shorted your motherboard it may have been along the back edge of the board underneath. Is there a metal ledge on the case below where the card slots are that may have been pressing against the underside of the board when you screwed it down?
