I have a dell laptop that starts out just fine, but after
a short time using it the cpu uasge for explorer.exe goes
to 99% and the system slows to a crawl. This is with
nothing active even.

The laptop is an Inspiron I5100 with P4 2.53G and 512M
RAM. It has service pack 1a installed as well as most
other windows updates.

Anyone know what the problem could be or have any
suggestions?

Thanks in advance.
 
How long have this happen? I suggest you scan your
computer for viruses with Norton or similar and for
spyware and others alike with Ad-aware. And finally to
check your startup programs and remove unnecessary ones.
You might also want to go to the Process tab in Windows
task Manager and see what program is currently running in
the background. You can close the program/processes you
know and under your name. Be careful what you close
though, it might disable some functions during your
current window session(Don't close explorer).

Symptom is similar to Blaster virus. Update your virus
program and run it. There are other similar posts in this
forum that have links to more technical explanations.

I am having the exact same problem with a new Dell Latitude 1.8ghz
Centrino with 60GB HDD, 786MB RAM 400mhz. I have scoured the earth and
can find no fix for this. I sure hope some kind soul sees this and can
steer us in the right direction. I've already swapped out RAM, CPU,
motherboard and only options are to reinstall WinXP and start from
scratch (God help me!).
 
is your spyware removal software and anti-virus software up to date? done a
check lately?

if you don't know what I'm talking about, go to www.download.com and search
in windows for
ad-aware and spybot - then download & install the programs & update them &
run a scan. delete anything they find.

what about your bios and chipset drivers? up to date too?

which service pack? sp1 (not sp1a) was famous for that.

have you tried an sfc /scannow?
