Vista - DRIVER_POWER_STATE_FAILURE - 5times a day

Hi,


I have been using Windows 7Ultimate & Vista Ultimate for over a year now...I use my wireless IDEA Net setter to access internet (!DEA - An !dea can change your life...)
My usage of Internet is approx 15-18 yrs a day and after usage of couple of hours ...the net connection automatically goes.
Even if i unplug & plug device again it doesn't start and few applications or sometime computer hangs. I have 2 forcibly restart the computer which again takes ages as...while shutting down it gives messages stopping services which is displayed for a long time post which it shuts down and restarts with a window says “Safe mode/network/ and start windows normally).
Reboot times differ but every time is close to 42415 seconds …and the nagging error comes that windows has recovered from unexpected error ..Details attached.
All drivers related to wireless/network are already installed but still I have to forcefully SHUT DOWN my laptop minimum 4-5 times in day.
I am attaching Physical dump files...do let me know why its happening and what is solution for same...I have all drivers up to date..still cant figure out..wts' wrong

Laptop Configuration:-
HP Pavillion Dv 6000
Intel Core 2 duo T 5550 @ 1.83 Ghz
3 GB RAM
Thank You very much in advcance...
