First it woke up from Sleep (close lid Sleep) with the screen content squished horizontally, eg the Clock widget instead of round, it looked fat. So did everything else (text, pictures, etc). So I closed the lid and re-opened it because that usually makes this issue go away.

It sure did, but a few minutes later I started getting erratic behavior, and then out of the, it blue-screened with the error message DRIVER_POWER_STATE_FAILURE.

A Google Search on DRIVER_POWER_STATE_FAILURE returned a number of results, including some explanations. This of course it's not just Vista, it also happens with other versions of Windows, because let's face it, they all come from the same blue screen software factory :-)

As the name suggests, one of the device drivers or other components of Windows has trouble handling a power state transition. So it does what it knows best, BLUE SCREEN! Here is what Microsoft's Knowledge Base thinks for the Vista bluescreens. Here are two posssible causes, one general sleep related, and another sleep and PPP related. Microsoft has a HotFix available but they recommend to only install it if you are getting this problem frequently. Otherwise they recommend that you wait for the next Service Pack.

From what I recall I got this blue-screen 3-4 times so far, in just over 2 months of daily use of this computer. Given that I put it to sleep/hibernate a few times per day, I will give it the benefit of the doubt. But if it happens again, I'll probably give the HotFix a try. Why not give it a try right away? A) Because I don't want to be an unpaid Microsoft beta-tester and B) because it may have other side-effects.

I haven't experienced any of those issues, but then I didn't spend much time with the default install: I put a new hard drive in and installed Ultimate. I have also made sure that I'm running the latest/greatest from nVidia for the chipset. The screen-squish behavior makes me suspect the video before anything else...

Yes, thanks, that's a good idea, I should check for the latest nVidia drivers. I only had the screen squishing with SLEEP. It hasn't happened (yet) with Hibernate.

I didn't pay attention before as to whether the screen-squish and the DRIVER_POWER_STATE_FAILURE happen one after the other. They certainly did today. From now on I will make sure I remember screen-squishes so I can link them to the DPSF bluescreens.
