Now I have more information.
Using a Shuttle motherboard, MV42N, I added (2nd drive) this 160 GB Seagate Barracuda 7200.7 HDD. I checked and LBA is on in BIOS, and the board is reading the drive correctly.
Using "AMI BIOS 7.00T".
Every time I access the new drive for any length of time, it eventually crashes the system suddenly, turning it off. It used to just stop, or freeze in the middle of a video file (movie) and I'd have to restart, and usually ended up with no sound until I restarted again. Then once we tried uploading 50 Gigs of data from another computer to the drive, for storage, and it kept quitting the upload, and we'd have to restart where we left off. I thought maybe it had a problem with power management scenarios, going into sleep or standby, but I don't know now, since it flat out shuts off the computer now when it wants to.
I downloaded Seatools, and ran the DOS test off a floppy, and the drive failed the tests, both short and long. During the long test, it found 95 sector errors, and I asked it to repair. Afterwards, the drive passed.
I did a full virus scan on the drive, in Avast, and it came up clean.
Around five hours after passing the Seatools test, I was entering the room, and the computer shut down on its own again. I threw the Seatools boot floppy back into its slot and tried to boot to it, unsuccessfully. The fans came on, but no beeps. I did a hard shutdown and started again, and this time got three long beeps, repeating indefinitely. I decided to reseat the floppy, just in case it was the problem, and it booted this time to the floppy, and ran the long test again on the drive in question. This time, two errors, which I chose to repair, and then a passing score again.
Now I realize that this probably means that the drive is failing, and I need to move data to another drive before it fails completely. But what do the three long beeps mean? AMI BIOS beep codes, googled, seem to indicate 3 beeps (short?) as a problem with the first 64K of memory, and "continuing" beeps (3?) as either video or memory problems. Then again, it could have just been the floppy not seated in its drive, or could it? It's not clear to me, since there is seemingly no direct reference to "three long beeps, repeated indefinitely" in any of the beep code lists I've found.
