I recently had a hard drive failure, just broke, so re-installed
everything on a new 120Gig drive. I am using XP Home SP2 and all
updates, 1.8GHz CPU, 1Gb RAM. All was well for a week or so, then
programs would freeze, Task Manager showed 2 copies of the program,
both marked as "Not responding." Trying to end the task did nothing,
and if I tried it 3 or 4 times Task Manager would be listed as "Not
responding." At that point the only way out was the power switch.
Since I had made an image of C & D (my program are on D) right after
the re-build I restored everything. That worked for a couple of days,
then I noticed that the start-up time was inordinately slow, 3 or 4
minutes, and I have the leanest start up folder imaginable. If I try
to use the machine shortly after the Desktop appeared I'd have to wait
maybe a further 2 or 3 minutes before the program would fire up.
Today programs are running oh so slow, each letter I type takes a
second or so to appear on the screen. Watching the CPU usage graph in
Task Manager it is at 100% at frequent intervals and continuously for
a minute or more from time to time. Yet the Processes window doesn't
show any process with an excessive CPU usage,
Just a final note on this saga...
The machine slowed down steadily during the day. I tried Process
Explorer, it showed more detail than Task Manager, but although there
were frequent excursions to 100% CPU usage at no time did the System
Idle drop to zero.
Things came to a head when I tried to start Eudora to send an e-mail
I'd been working on for days. The text was written in Word, and I had
intended to copy and paste it into Eudora. Well when Eudora started
the screen went white, blank, except for the name at the top. Since I
couldn't do anything, or see Process Explorer I made a cup of coffee.
A good 10 minutes later Eudora started up. Now I went to Word to copy
the text. There was no text! File > Recent was blank, File > Open was
blank. Nothing in My Documents, not a single file. I did a search for
the file by name, blank. By a word in the text, blank. Using a file
reccovery program, blank. I wasn't too worried about the contents of
My Documents, I have back-ups, but that file I saved only an hour or
so before this happened is gone...all 8 pages of it!
I tried the MS malicious software tool, Grisoft AVG anti-virus, Ad
Aware, SpybotSD. No problem found.
I didn't bother to restore an image, went back to the restore CDs.
Have been wading through re-installing and updating everything. Just
one niggling concern...is it possible for some threat to remain hidden
in the root of a drive?
