I'm pretty sure I know what the answer to this is but thought I would check with everyone here for a second pair of eyes to see if I have gone over everything.
The other day I was playing some Donkey Kong, having the best round of my life....probably would have set world records

when my system blue screened. Try to restart, nothing. I just get the error, disk boot failure after the bios info loads.
Initial thought was a hard drive issue but I think I have since ruled that out.
Here is what I have done:
- Tried to find hard disk within bios....does not show up.
- Inspected for bulging caps, has solid caps so can't tell.
- Cleared CMOS.
- Disconnected all peripherals and even went as far as moving from vid card to onboard video...same error with both modes of video.
- Change from IDE to AHCI...same error. Then back to IDE....same error.
- Tried putting only one stick of memory in and when that didn't work, used the other stick to rule out bad memory.
- Replace hard drive with 2 different known working hard drives...same error and they don't appear in bios either.
- Tried to flash bios with latest version but can't boot from freedos disk or usb with bios bin on it because it pops up with the same disk boot failure.
I pretty much tried everything I can think of to troubleshoot short of trying a new PSU but can't imagine that is it. Seems like it is something with the mobo not detecting any IDE/SATA devices. It will recognize USB however as that is how the dvd drive and usb for the flash is connected.
Is this board dead? Or at least that portion of the board? There was no electrical surge and the unit is on a power strip.
Current hardware is:
mobo: Asus M3N72-D (can't find replacement on ebay)
Proc: AMD Phenom 9750 Quad Core (had it laying around free when first building mame)
Vid Card: XFX 8600GTS
Mem: G-Skil DDR2-1066 PC2-8500 (2x2gb)
If mobo is dead, can anyone recommend me a replacement board since the current one isn't on ebay? Any out there that you know of that I can use existing memory, proc, vid card (or perhaps one with built in and better vid card)??
Thanks for taking the time to look at this and any info you can give me.
