mouse and key strokes slow to respond

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

My mouse and key strokes are slow to respond, running Windows XP Pro on IBM
Thinkpaid. The message getig in the MMC is i8042prt, solution is to increase
the mouse overflow buffer. I did and it worked great, then 2 weeks later same
problem I have increased this twice and it is not helping. Anybody know what
else to do or how large you can increase this mouse over flow buffer.

thanks james
