Need help with a Acpi 2.0 error in Event Log.

The Acpi 2.0 _PCT object returned an invalid value of 7.

This keeps coming up in my event log on my laptop. When ever I am in a game this error happens. I can't clearly find this answer any where. I've looked at microsofts website and searched countless forums. This forum is the only place that has seen a problem like this before but it was a value of 11.

Any help would be great...this has recently only come up in the past month it started 10/19/2006 and has been happening ever since... Please help.

My laptop specs are:

Amd Turion 64 ML-44
2 gig ram
Go 7900GS x2 SLI Enabled Nvidia
nforce 4 mobo msi
