This relates to a HP Pavillion DV7 3111ea running Windows 7 Home Premium 64bit. The original OS was factory installed and the system is about 1-2 years old.
I have re-installed the OS from a DVD but the same problem remains.
I am constantly getting a 9F stop on the machine every time I shut the system down. It goes through the normal log off and shut down screens, the monitor turns off and the hard drive seems to turn off. My problem is the power LED's, wifi LED etc all remain lit along with the system fan running. After a while I get the BSOD.
