ACPI IRQ handler not compatible

Action Center reports
ACPI IRQ handler not compatible with this version of windows

Troubleshooting offers no solution

It has only recently appeared after some updates and installing some software including Photoshop CS5 and an older 32-bit image organiser, Breezebrowser, but I'm not sure when as there was no pop up message.

This is win 7 pro 64 running on a Dell 580 i5, 6Gb, 1Tb (this is the original installation, not an upgrade)

Any suggestions, or can it be ignored? I thought win7 didn't need IRQ handling

Thanks

Hey.

You'd probably be well off installing the latest packages in the downloads/utilities section for your motherboard on the manufacturer's site.
