|Today the computer exhibited a new behavior, which I will present below.|
Upon being turned on in the morning, after a night-long shutdown:
Two consecutive beeps
Black screen with the following information presented:
Phoenix ROM BIOS PLUS Version 1.10 A05
Copyright 1985-1988 Phoenix Technologies Ltd.

Dell DM051 Series
BIOS version A05
Drive 2 not found: Parallel ATA, PATA-0 (PRI IDE Master)
Drive 3 not found: Parallel ATA, PATA-1 (PRI IDE Slave)
Strike the F1 Key to continue, F2 to run the setup utility.
I pressed F2 and looked into the BIOS but didn't know what I should change and how, so I exited BIOS setup. Windows managed to come up after approx. 2-3 minutes.
The second time today, after a half hour shutdown, upon being turned on:
Black screen with the same message as above
This time I pressed the F1 key and Windows came up.
