Overclocking Oversight

Was fiddling with the O/Cing settings of my asus mobo tired the other night, boy what a mistake that was. I forgot to set the PCI clock to stay at 33mHz. So I'm assuming that my PCI cards didn't like it when I cranked up the multiplier on my CPU to 14x. This is all immaterial to my current problem, however, as I'm pretty sure My mobo is dead, but am seeking confirmation from you fine folks.

After resetting the CMOS, she seemed to boot fine, I went into the BIOS and changed my settings back to enable RAID etc... Everything seemed fine, except, now it won't boot past the PCI device listing. It lists my PCI devices and IRQs etc..., but then hangs after displaying the list. Also, the reason I think its the mobo, is that then the data thats already displayed becomes somewhat corrupted, a few letters disapear from the screen, and others half disappear, but it wont boot past this point.

I'm quite certain its not the HDDs, In the boot process prior to the point where it hangs it lists my RAID setup as 'healthy', and all drives appear a-ok in the bios.
I don't think its my psu, as all the voltages from it appear to be fine according to the bios.
I hope its not my VGA card, since it still displays everything up to that point.

So I'm thinking one of 3 things is wrong:
1. Motherboard is dead, I fried the PCI bus. (Is there any way to fix this other than replacement?)
2. Procesor is dead. (Thank god AMD just slashed prices...)
3. PCI cards are causing the error (VGA or sound card)

Thanks for any help or suggestions you might be able to offer.

Changing multiplier shouldn't affect PCI clock, only changing the reference clock will do this.

Remove the battery from the motherboard and make sure CMOS is well and truly cleared. No luck? Remove all PCI cards, try again. No luck? Try another graphics card.
 
No dice, the bios was most definetely cleared. Just cleared it again by taking out the battery, with the same results. Took out the pci cards, same result. Tried booting from the CD-rom drive to a copy of Ubuntu I had lying around, no dice. Don't have another PCIex graphics card around, so I can't test that. I ordered a replacement mobo, so I guess I'll find out if its the mobo thats the problem in a few days. Got a A8N open box off newegg for cheap, figured the open box'd be fine since I already have all the accessories for that line of mobos.

However, do you think that its the mobo that's the problem? Are there any other steps I could take to further trouble shoot this issue?

Thanks much,

Don't know, if this will work, but sometimes ram info is still saved (I dunno tho) try to manually change mem/cpu settings, make sure they are normal and not overclocked. Try to mess around more w/bios maybe that'll fix it 😀
 
So I can't boot to a hdd, nor to a CDrom, but it's booted memtest86 fine. I'm going to let this run for a bit to make sure its not my RAM.
 
Got it to boot by unconnecting my optical drives and disabling every hdd except the boot drive. Now I just need to figure out which of these devices, if any, is the dead one that was causing the hang at the ACPI pic listing.
