Last March, I had the Windows 7 Home Premium, 64-bit operating system reinstalled on my Dell desktop computer.
The computer worked perfectly after the installation. I sense that there is no relationship between this event and what I describe as follows.
Since then, on several (six or seven) occasions at long, odd intervals, when I first turned the power on, the computer (apparently the hard drive) has made an ominous “whirring,” mechanical (rather than an “electrical”) sound—as if it was spinning and not engaging somehow.
On at least four occasions that I clearly remember, I could only stop the noise by shutting off power to the computer.
(When I restarted the computer, the sound did not recur and the computer started normally.)
I currently live in India, and the electricity supply here is very erratic.
A few times, when my computer was installing and configuring downloads, I had to shut the computer down before they were completed—because the UPS was running out of power.
I do not remember clearly, but I believe that the problem began at one point after I was not able to shut the computer down normally.
Now, to the present issue:
Increasingly, over the last 6 – 8 weeks, when I turned on my computer, it seemed to hang.
After I turned the computer off and on again, it started normally.
The computer has stopped hanging when it starts up.
However, now, almost every time when I press the UPS power button, the computer starts up without my pressing the power button on the “system unit.”
After the computer then starts up (after the Dell logo appears, but before the user log-in window appears), I get the message: “CMOS checksum error – Defaults loaded. Press F1 to continue.”
After I press the F1 key, the computer then starts normally—except for the fact that I must reset the date and time.
I have tried to use a repair disk that I created after the operating system was reinstalled the last time, but the computer will not recognize the CD/DVD player.
So, finally, I have several questions:
1. Do you have an idea as to why the computer (or hard drive) made the “whirring” sound?
2. Do you feel there is a relationship between the sound (or the hard drive going bad) and the fact that the computer is not booting properly?
3. If you feel there is not a relationship between the sound and the fact that computer is not booting properly, do you have an idea as to why the computer is not booting properly?
4. Do you feel that the problem with the sound and / or the computer not booting properly could be solved by simply reloading the operating system?
