Mouse freezes on full mode

I have an hp pavilion desktop pc with windows vista home premium, tow days
ago, for no apparent reason after logging in, the mouse freezes on the pc,
sometimes also the backspace doesn`t responde on the password, the thing is,
they are basic generic keyboard an mouse, both ps/2, and in safe mode they
work just fine!! What could be loading in full mode that makes a conflict
with the mouse?? I downloaded an update for multimedia keyboard from hp, It
didnt work,
I checked on msconfig to see if there was something weird at startup and
everything seems ok, I tried with a restore but nothing. Can someone give me
a hand, i´m lost.

Tried looking in Event Viewer for any err's?
Tried disabling all startups in msconfig, then rebooting & accepting the
info msg?
See if its the same
If no change in msconfig, hide all MS services, disable the rest & reboot
