i'm not sure what's going on.. My computer has been fine for 6 months now and suddenly it had two crashes within 21 minutes of each other. I'm waiting for more crashes to report them but here is what i have so far.
The crashes you have are normally caused by a driver but other than a couple of windows drivers there is nothing significant pinpointed. One dump does show missing or corrupt files. I would first use this guide to test your memory, then if that does not produce any significant results move on to the hard drive test and report back.
