Hi,

PCI devices can share IRQs, therefore you may see a device "IRQ Holder for PCI Steering" on the same IRQ has another device, this is normal.

If there are no devices in "Device Manager" reporting a conflict with a yellow dot and exclamation mark then you're probably OK.

If there are any devices listed in "System Information" conflict section that are causing you concerns, let me know what they are.

Thx for replying,heres a copy of my IRQ list.I was told by a technician at Creative Labs that my sound card(SB) should never share an IRQ with something else.As you can see,its shared on #10.I've looked into my BIOS to see where I could possibly reassign it,but can't figure it out.Any ideas?I read that it's possible to reserve IRQs,but my BIOS doesn't look like the one they described,so I'm lost there.

Hi,

The "ACPI IRQ Holder for PCI IRQ Steering" is normal in Windows and I do not think it is the cause of your problem. There is no way in any BIOS to change the IRQ "ACPI IRQ Holder for PCI IRQ Steering" is using because it is put there by Windows.

You now have three different threads open with lock up problems.
I will close this one and we will continue the discussion here:
