PS/2 mouse data buffer overflow causes freezes

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

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.
