I have a HP system, a Pavilion s7621.sc, with windows 7 32-bit installed.
I have tried installing the chipset driver, but the problem is not fixed.
When I look in the device manager and look for the hardware ID I only get this ACPI\AWY0001 *AWY0001, I can also find this PCI\VEN_8086&DEV_27BD&SUBSYS_2A44103C&REV_02\3&11583659&0&F8
I searched Google with the error code you have and received a number of hits. You might want to give that a try for an answer.
