Hi Rick,
Yep, I was thinking along the similar lines, it could be the drive is on
it's way. Thanks for the tip regarding the power supply. Yeah, I can
handle the process of checking the voltages. I'll connect up my Fluke
multitester and see what kind of voltages I'm getting. Actually I was
kind of wondering about a possible power supply problem as I have seen
similar behavior on other machines shortly before a power supply crap
out. Unfortunately the machine ain't no longer under the Dell warranty
so I'll have put out the cash if it needs a new drive. If it's a power
supply I have plenty of those laying around all over the place. :)
Good advice on cleaning the machine out. It's well overdue for a
dusting. These machines tend to collect more dust than a vacuum cleaner
and I haven't been getting around to cleaning them as often as I should.
Much Thanks.
