On my windows XP SP1 system, I was connected to the
internet via LAN (University Hall of residence) and
whilst looking at some web pages , my mouse froze up, for
around 30 seconds at a time.
Then it would work fine, then freeze up. Also the
internet stopped working at the same time. In the task
manager CPU was running around 50% (2GHz processor)I was
also running Zone Alarm 4 firewall.

I had to reboot, and I that I had to reconfigure Zone
Alarm again to accept my internet programs for use. I
checked the control panel for the event viewer and I had
several entries as expected for source i8042prt, Event ID
12,

'The ring buffer that stores incoming mouse data has
overflowed (buffer size is configurable via the PS/2
mouse properties in device manager)'

In the help and support page it says Product: Windows
Operating System
ID: 12
Source: i8042prt
Version: 5.0
Component: System Event Log
Symbolic Name: I8042_MOU_BUFFER_OVERFLOW
Message: The ring buffer that stores incoming mouse data
has overflowed (buffer size is configurable via the
registry).

Explanation
This event record indicates that the buffer that stores
mouse movements and clicks filled up before you stopped
typing. It means you entered data faster than the
application could process it. Some of the data was lost.


User Action
Wait until the application has processed the stored mouse
input, and then enter more data. Be careful not to work
ahead too far. If you get this message often, the buffer
size should be increased by someone who is familiar with
Regedit32 (Usually the person with administrative rights
on your computer.).

Now I only had internet explorer 6, the firewall and
bitdefender antivirus running, so CPU was at an average
of 5% before the mouse freezed. The freeze affected my
keyboard and the whole system.

I have since changed the mouse buffer to 300 in the
control panel. Also I went into the registry under
MouseDataQueueSize and changed the value to 300 decimals.
There isn't a way of knowing if this method will work.

I have read that the buffer overflow is just an effect of
another system problem, although there is nothing
anywhere in the event viewer that there was an error
before this happened.

The question is, whether it is my connection to the
internet that caused the freezes, as I experienced this a
few times in the first year.
The next year I was not connected to any internet and I
had no freezes.
Now the third year I'm re-connected and the problem
occurs again...
Can anyone shed some light over the problem?

Try using a USB mouse for a time... If that works out OK then there is
probably a really oddball resource conflict in the system. You might also
check to see if the computer mfg has any info, BIOS updates or patches for
this issue.

Good Luck,
Len

I am having a similar problem, when my PS/2 mouse is plugged in, i cant
access broadband, if i take the mouse out, the broadband modem works, i
bought a usb mouse and managed to get onto broadband briefly, but with the
keyboard not working this time, but after turning off pc and starting again,
the same problem occured. Having to use dial up for now, any help would be
appreciated.
