Driver Power State Failure help  

Hello!

So there's this problem that I'm having with my computer. (laptop)
It seems to take absurdly long to shutdown, and I occaisionally get the BSOD 'Driver_Power_State_Failure'

Also, the CPU usage ranges from 70-99%. This is definitely not normal behavior.

I used to be playing Starcraft II with everything on medium-high, and have no issues whatsoever, now I'm even having trouble with low settings.

My laptop is an Asus k42jv, 4gb of RAM. What information do you guys need?

EDIT: Did I mention that previous BSODs had the computer collect data for crash dump, and recent BSODs have my computer crashing on the BSOD? (i.e. it's not able to collect data during the BSOD)

EDIT2: The latest BSODs : A device driver attempting to corrupt the system has been caught. The faulty driver currently on the kernel stack must be replaced
with a working version. This happened during shutdown, and when I rebooted, I was sending Microsoft information about 'this unexpected crash' and all of a sudden I was greeted with another Driver Power State Failure BSOD. My computer is extremely laggy and is constantly running at full speed (I can tell from the fans). Urgent help needed!

When you get the bluescreen, do you get this information on the blue screen :
"Stop 0x0000009F"
and this: "(00000003, parameter2, parameter3, parameter4)" ?

Without dump files your job will be made much harder, because if you can't identify the exact driver that is causing the problem then it probably makes sense to replace/update all of you drivers, one at a time.

Sometimes when you look at the Properties for your devices in Device Manager you might see a problem device clearly. You also may have clues as to which device from your use of your laptop. And of course, if you've made any system changes or installations around the time the behavior cropped up now would be the time to mention that.

Have you made any system changes or new installations recently?
Why do you run CCleaner often?

Where I'm going with these questions is that if your problem began around the time you made any of the above changes that would make figuring out what driver is causing the blue screen much easier.

If those are changes you made after the problem began then they are just 3 items to scratch off the list of suspects.

Another test you can do that is much fastrer then uninstalling and reinstalling drivers is to go into Device Manager and disable the non-critical devices temporarily (one at a time) to test to see if the problem disappears. These would be CD/DVD drives, Floppy, printers and imaging devices, network adapters, portable devices, and sound-video-game devices.

No, cleaning up files with CCleaner is not a problem, but CCleaner does have a registry cleaner too. "Cleaning" the registry without knowing what it is you are removing can cause problems. You should only use the registry cleaning function to deliberately remove known leftovers. Like when you uninstall drivers, for instance.
