Vista - screeching noise from tower

I have a new, fairly high spec PC; anyway it has an index base score of 5.7.
I am having great difficulty putting it into hybrid sleep.Most of the time it
works but about one tenth of the time it either refuses to sleep ( it just
hangs with a black screen)or it sleeps but won't wake up again. Either way I
have to press the power button on the tower to boot it up, thus losing any
saved work. Sometimes when I press the button a screaming noise comes from
the tower ( not from my system speakers ). The only way I can stop it is to
keep the button depressed until it shuts down.I consulted the help and
support thing and it claimed my cordless mouse must be to blame, something
about a conflict with other USB devices trying to turn the PC off. So I
bought a new gaming corded mouse but it's still happening. I am worried that
it might be damaging my computer. Anyone got any ideas? Cheers,

out the fans on the graphics card too. So that might be the screaming. The
7.10s have just been released *if* you've got an ATI graphics card you might
want to give them a try.
