Disk Boot Failure - after hardware repairs

I recently started a thread on replacing my video card, but rebooting has made it evident that there is a larger issue at hand, as well (a new video card still appears to be in my near future).

I had to replace the screeching Northbridge chipset fan on my Asus mobo. I had to pull the mainboard out of the case to do so. I was careful and all, but the PCI-e x16 video board would not produce an image and upon boot up, I would hear a beep, followed by 3 or 4 beeps. I couldn't tell what that meant, having no image. The monitor would not even change status from standby. I moved the PCI-e board to the other PCI-e slot but no still no image. Pulled the card and installed my backup.

My backup video card (PCI) installed fine and I have no beeps except for the one that accompanies the message "Disk Boot Failure, Insert
System Disk..." that I am getting. If I restart, go to the Boot Menu (F8), and select HDD 1, it works fine until I have to restart/reboot and the same thing happens over and over. I changed the Bios setting for boot up from removable, HDD, CD to HDD, CD then removable, but the same thing happens. All of my drives and devices show up appropriately in the Bios and upon booting up.

So, the HDD seems fine. Any ideas, maybe related to the video card going out? Thanks for any suggestions. Lar

 

Well, in desperation, I went back to the Bios and looked around there. I found that the booting order of my two non-RAID HDD's had become reversed and one with windows had become second in the HDD boot queue.

This seems to have solved that problem. I hope that this helps someone in the future.

 

I have a similar problem but I'm not sure what the tone means. This involves a Compaq Presario S5200NX. The original problem as explained to me was a wipe of the HDD by magnet. At power up there is one beep, then a continuous quavering tone. I determined it is not a DIMM tone. The Compaq opening screen appears and that is all. There is no mouse or KB function. All drives were removed and still the tone. Tested HDD and it is not accessible or even recognizable on another box. Any ideas?

 

Actually I was looking more for an idea of what the tone means. It would seem to indicate a portion of the on-board functions which, depending what it is, would mean the MB was a complete write-off. I just was curious if anyone could verify. All drives and add-on cards have been removed. There is no KB or mouse function when powered up. Video is present. As far as the HDD is concerned, I'm pretty sure I can revive it. Looks like the boot sectors have been wiped.

 

I had my PCI-e 7600GT board checked out and it is fine. So, I pulled the mainboard again and got out the magnifier. Sadly, I found that I scratched (more like crushed) 3 tiny traces next to the pin that holds the Northbridge fan down.

So, can these things be fixed or is it not worth it? I have attached a pic for your (mean-sprited) pleasure.
