The speed of processor 0 is being limited by system firmware. The processor has been in this reduced performance state for 35997 seconds since the last report.

Background info:
1. The notebook was doing PV360 rendering over 48 hrs.
2. Vista 64sp1, SW2009sp3
3. DELL M4300, FX360M, Core2Duo T7800, 4GB Ram
4. CPU temp 65, GPU temp: 75

Any advice?
