I decided to try opening in Safe Mode because of all the problems. I ran a Trend Micro antispyware scan, and found about 8 spywares. The other interesting strange thing is that while in Safe Mode, my computer did not have a disk boot failure even though it was unattended for about 3 hours. Lately, my computer has a disk boot failure almost always when I walk away for several minutes (15-20 min.). I wanted to check it in Safe Mode because I was concerned that maybe someone was accessing it remotely since it seemed like there was activity when the computer was powered off. When I checked the times carefully, however, I found that this was incorrect. It was only having errors while powered on and in use by me.
The chirping sound has not occurred lately, but I am still getting disk boot failures. When it chirped, it was more like a whirring sound - as if something was wrong with the hard drive. But since I keep getting clean bills of health for the hard drive, I just don't get it. When I ran eventvwr this evening, it had the same four "events" it has had over the past week when this all started. They are 7001, 7000 (twice) and 7023 from the Service Control Manager. These are all listed as errors. What can I do to save my hard drive???
How do I boot into my bios setup?? Dsenette? Someone once recommended this a while ago for another problem, but I don't remember how to do this.
