my mouse cursor moves by itself when i am offline (opens startup menu etc)
,the mouse cursor also freezes, so that i am unable to move it and need to
reboot. Is this a virus, and if so why is my NAV not picking it up , i have
done a complete scan of my PC, but nothing was detected? Is it possible
that somebody could have network enabled my PC and is controlling
it with a trojan when i am offline ? I have not checked whether this
behaviour
persists with my modem switched off. Have also not discounted the
possibility
of doing this via power cables ? any feedback appreciated. If this is
an unknown virus then would appreciate some pointers on how to locate
infected files and report these to Symantec.

Does this happen with *every* mouse attached, or only with a certain
one? Is this certain one a radio mouse, whose batteries are running low,
or which does interfere with other devices like a cellular phone or a
walkie talkie?

Dear George,

I've seen it in the field and in the office. Normally it's just a sussed
mouse. Swap it over and see if the problem goes away. If not it may be a
corrupted mouse driver (if you've loaded on OEM drivers).

One final reason may well be that the mouse port (PS2 or serial?) has blown.
Don't laugh, again I've seen it happen. Theoretically it shouldn't occur but
I've seen anything things to know theory can get stuffed half the time.

Good luck,

Ka.

Going back a few years when you couldn't share IRQs like you can now
(supposedly), an IRQ conflict would cause the mouse to take on a life of
it's own. My Ma's Win ME (eeeek) laptop does it - the modem will drop the
connection, the speaker screams out and the mouse pointer dances a cha cha
across the screen. Pretty certain it's IRQs but you can't manually set them
so just have to live with it :)

Maybe I missed something in the beginning of this thread,
but why can't the device manager juggle the IRQs?

Don't exactly know but on my Win 98 SE PC it just tells me that you can't
alter the IRQ so I assume it's the same across all Windows - must be some
reason for it. Probably something to do with the way IRQ sharing is
managed.

Arrrrggghh no! Don't mention that O/S!
If it's the IRQ, then you can also go into the BIOS and set the IRQ setting
to optimised BIOS settings.

That's provided you've got the option and that it's a USB mouse.

If it's a USB mouse, then there's also the freak occurrence of fluctuating
power. I doubt this very much in a home setting.

With my former clients, they had heavy machinery on site that drained power
like nuts and just played merry hell with the computers.

Good luck.

Sometimes the problems is that different devices can end up using the same
IRQ.
You see this problem more with sound cards then with the mouse. Like the my
SB Live card would blue screen if I use the default sound driver because of
an IRQ conflict related to the motherboard I'm using.

In more recent times, I would have IRQ problems due to a conflict between a
multi IO card and an internal modem that's a pre-req for the system I use to
deal with. Both device needs the IRQ at the same time and I end up having to
try and manually move the device to the IRQ or the card just won't work.

I think conflict between IRQ should be pretty rare these days, provided
you're using new hardware and not forced to do what I had to do and MacGyver
bits from old computers.

Good luck,

Ka.
