I know nothing about crash dump analysis, but a friend at work had a similar problem with her office computer. I watched the tech guys go to work on it.
The likely causes boiled down to three: bad RAM, an HDD or file system problem, or a corrupted driver. (I was told PFN_LIST_CORRUPT errors mostly point to driver issues. Not sure how accurate that is.)
As a first step, I'd suggest you test your RAM and your HDD with the approproiate utilities. For RAM, use Memtest86+. It's free and downloadable. You just need to burn the ISO onto a CD and then boot your machine with it. Let the test run for at least 7 complete passes -- the more the better.
You can try to use Windows to check your drives for errors. If for some reason you can't, try to acquire a copy of whatever disk checking utility Hitachi offers. Seagate has SeaTools, which I'm told works with drives produced by other manufacturers.
Once you've ruled out hardware, then you move on to checking your drivers. I'd go at it one by one, uninstalling each driver and sweeping with a cleaner until I get to the culprit. (Any exclamation points in Device Manager, by the way?) Or you can enable Windows' built-in driver verifier to find out which. Not too familiar with this utility, but you can read about it here

(I think it's safer to disable it after you've checked your system)
Good luck!
