Hello everybody,
I have an annoying problem with my WinXP. After upgrading to SP2 with
Windows Update, I noticed that the bootup was very slow (2 minutes in
comparison of the 30 secondes of my WinXP SP1). I reinstalled a fresh
WinXP SP2, but the problem is still here. The only change made was the
operating system, the hardware, drivers and applications are still the
same. The machine boots quickly enough, but after logging in the disk
works like mad. It takes about 2 minutes before the disk activity
settles down. This issue is related to Windows only, because the
slowdown was already present just after the installation of SP2, and
just after the re-installation of a fresh WinXP SP2. My PC in a
standalone computer and is not connected to any network.
I have tried everything to solve this issue : defragmentation of C:,
chkdsk, new IDE drivers. I spent many hours playing with Msconfig and
trying to reboot without any startup processes. I have disabled many
services, including Antivirus, Firewall and Indexation service. My PC
is absolutely clean (no virus, no trojan and no spyware).
After a while, I used Bootvis, a very powerful program from Microsoft,
and I discovered that my problem is related to the process
explorer.exe. After 40 seconds, explorer.exe is opening hundreds of
files on every HDD (.exe, .Dlls, .lnk, etc). Disk utilisation remains
solidly at 100% during this operation (but CPU usage remains low
during the entire process). Looks like Explorer.exe is searching for
icons or "prefetching". When Explorer.exe stops doing that after 1
minute and 30 seconds, the system becomes responsive and stay stable.
In order to help explorer.exe, I have deleted the preftech directory
and the IconCache.db file, without any results. And no anomaly in logs
files ...
During his madness, Explorer.exe also try to reach unknown files,
because bootvis shows lot of errors messages like E:FObj_NotFound or
F:FObj_NotFound (again, I have checked the disk with chkdsk and others
tools). I don't want to reinstall my WinXP again, because I'm sure the
issue will still be here. I just want to UNDERSTAND what going on with
Explorer.exe during the bootup sequence, and desactive forever his
"read every file" behavior.
Astonishingly, a search on Google for "FObj_NotFound" don't give any
result, and it is also the case with the Microsoft knowledge database.
A search on the newsgroup with Google shows that I am not the only
people with this issue, but unfortunately no troubleshooting is
provided. Could you please help me to understand my problem ?
Thank in advance for any help !
