Hi, przemekjab.
Have you tried the System File Checker? At the Run prompt, type: sfc
/scannow
SFC will compare each WinXP operating system file to the "known good" copy
held in your on-disk cache and replace any missing or damaged ones.
But you said, "I don't want to reinstall windows, as this is a pain (done it
already several times)". Reinstalling is even more thorough than SFC and
should have fixed any problems that SFC would fix.
If you DO decide to reinstall WinXP again, be sure to check Microsoft's
instructions for an "in-place upgrade". This will reinstall WinXP, but
preserve the Registry, so that it does not wipe out your existing
applications and data. It's as much "a pain" as a full reinstall for WinXP
itself - and you still must visit Windows Update, after getting your
firewall and antivirus back in place, to get the latest SP and later
hotfixes - but it does avoid the pain of reinstalling the apps. See this KB
article:
How to Perform an In-Place Upgrade (Reinstallation) of Windows XP
http://support.microsoft.com/default.aspx?scid=KB;en-us;q315341
But all this should not be necessary. If these symptoms keep coming back
after all this, you need to look in some other direction for the problem.
Have you tested your RAM? Your other hardware? Connections and cables?
When I asked Google to search the KB site for "explorer+cpu", I got over 300
hits. You can start with this one and then ask Google to find the others
with "Search site":

Every time I click either on windows explorer, any folder on the desktop,
or try open Control Panel, they do not open and instead of it my
explorer.exe gets up to 100% CPU, making impssible to work. I can however
open Task Manager and use it or shut down the computer. I can kill
explorer.exe then in Task Manager (disappearing taskbar, etc.) and then when
I start it again (from Task Manager) all is back to normal, unless I try
again to open any application mentioned above, all related to explorer, and
the whole thing starts again. Very enjoying, as I have to use other programs
for files browsing.....and can not access Control Panel (is there an other
way, by the way?) This happened roughly after I did these operations -
defragmented C: drive, installed some "necessary" MS Windows patches,
browsed the Internet..I have the newest, updated Norton Antivirus, always
on, run the scan on the whole computer, no viruses, run Lavasoft Ad-aware
removed all staff, restoring to the previous point also does not help.....I
don't know what to do. I don't want to reinstall windows, as this is a pain
(done it already several times), but this time I have so much stuff I need,
all updated to the latest versions, with all upgrades and patches, that it's
almost impossible to reinstall it all. HELP!!!!!!!!!!!!!
