Hello,

I have a rather new computer with Win XP Home. I quite often get
IRQI_NOT_LESS_OR_EQUAL or something liek that. I was told to look in the
device manager from a website and when I view Recources by Type and click on
the IRQ tab I find that mu USB and Video Card are both using 16. I disabled
the USB thinking it would stop the problem but it didn't. Can I change the
IRQ for one of them?? Will that fix it. I have latest Drivers ect.

Cheers

When does this happen? If it happens when you shutdown, there's an
entry in the knowledge base about a conflict between a USB mouse and
some newer AGP video cards. Logitech's latest mouseware driver fixes
this, or at least it did in my case. Not sure if such a fix was ever
available for the MS driver.

This happens when I start up the computer, generally after I have logged in
but before the desktop is displayed. It also happens as I am starting
outlook and outlook express. I'm not using the USB port for my mouse. I have
a ps2 adapter. It usually only happens in the first few minutes of starting
my computer for the first time that day. I can reboot and it will be ok :s.
(I have a microsoft mouse not logitec, I've read about logitec but)

Thanks
 
The problem is IRQ sharing - its a feature built into windows 2000 and XP
that is enabled on any system with a ACPI compliant mainboard (which is all
modern boards) - in my family we have 4 machines all running W2K and none
work well with IRQ sharing - it causes stuttering during media playback at
best and bluescreens in the worst case as you describe.
Unfortunately it requires a reinstall of the OS without ACPI or disabled in
the mobo Bios but thats what we did and it cured our problems.
Truth is I think Microsoft stuffed up big time by introducing this feature
as they give you no software option to reconfigure IRQs easily also on
modern PCs nobody uses old devices and you can disable serial ports and
parallel port to free up IRQs.
Do a Google search on disabling IRQ sharing and read the support pages at
Microsoft plus other websites - you'll see its a fairly common problem.

Plenty of people have win2k & XP boxes with no stuttering problems,
without these reconfigurations, using ACPI. You ought to consider
different sound(card) or drivers... something
