I am not terribly computer-savvy so please be patient if I don't include information or need tons of clarification.
I have not made any changes to this computer for 6 weeks when I hooked up my wireless network router. Then, my computer shut down unexpectedly in the middle of the night. The event log told me it was a BSOD with a minidump file and a sysdata.xml file.
The next day, it did the same thing, which is why I doubt the first problem was a fluke. The computer did download updates for windows automatically a week earlier. I'm running Windows 7 64-bit on an HP.
Hopefully, I have attached the dialog box info in the zipped file below.
