Re: XP freezes on rapid cursor movements under heavy cpu load

Ever run any type of Registry Cleaner on the PC ? It's MSInfo32.Exe
that you should be invoking. I wouldn't toggle the enable bit for
"LargeSystemCache" on a notebook PC. Hardware listing in Device
Manager won't show 100%, unless you add a System Environment
Variable "DevMgr_Show_NonPresent_Devices" and set it's value
= 1 and then tic/check "Show Hidden Devices" in Device Manager.

I'd concentrate on the Synaptics TP driver as the cause. Sometimes
you can use the "Generic" latest driver from Synaptics' website instead
of the one provided by your OEM. The mouse pointer issue might
also be related to your Video driver so a check for the latest one is
also a good idea.

Hi,
when I "work too fast" under heavy system load, i.e. I switch between
task windows, open and close browser tabs and move the mouse cursor
rapidly across the screen I experience random system lockups (system
hangs or system freezes). I can only press the power switch and
restart the system.

It happens about once in 48 hours but it happens out of a sudden, I've
never found an error message close to the crash time in the logfiles.

I am running XP-pro SP2 on a Mobile AMD Athlon XP-M 2800+ Fujitsu
Amilo K 7600 Laptop PC with 1GB of RAM

Video: KN266 integrated S3 Prosavage 32 Mbyte shared memory, true
color
Audio: 18-bit stereo audio (AC97)
Pointing device: Synaptics Touchpad, SynTPLpr.exe running but not
SynTPEnh
a D-Link Airplus DWL-G650+ wireles adapter sits in the Cardbus slot
(PC-Card, PCMCIA)

Hardware Manager shows a clean tree without warnings.

My web browser is Firefox 2.0.0.6. I always have at least 2 dozen
browser tabs open so Firefox consumes up to 350-400 MB of my 1000 MB
RAM.

I tried to run msinfo but I get the Windows Help window.

I have changed Windows' performance options to give background
services more CPU time and to give programs more memory. I feel that
helped a little. But Firefox appears a bit lame now and the freezes
still occur.


What else should I try?

Best regards,
Dieter
