i can imagine yr frustration
sry but i'm not sure how to give u an exact solution.
oh wat mouse r u using?
here's wat i'll do if it's my pc
. if the mouse comes with a driver like Logitech's i'll uninstall that and try.
. see task manager's processes and running apps.
. i'll download Microsoft Sysinternals tools to
.. look at the processes
.. check autorunshttp://technet.microsoft.com/en-us/sysinternals/default.aspx
. switch to older motherboard drivers to check
. do clean install XP and don't install any drivers and see if that works
.. with no drivers install, mouse works - it's driver. try install 1-by-1 to c which 1 is the culprit.
.. if it doesn't work with clean install, it's native in win XP.
. scream at the sky and the mouse before calmly update my motherboard's BIOS, with a UPS protecting the PC from power failure.
. i would remove power to dvd-rom, unnecessary usb devices, network adapters, non-XP-boot hard disk during testing.
. use built-in INTEL VGA during troubleshooting. remove PCI-Express VGA & other cards.
hope u find the answer sir.
