Microsoft Windows 7 Ultimate: x64 (SP1)

Jumping in for a short while - Do the already suggested troubleshooting steps if you haven't already.

  • If you're able to get into Windows 7 sometime, type MSCONFIG, select Startup and disable everything except Microsoft software.
  • Ubuntu
    For a trial, try downloading a copy of Ubuntu and see if your system will crash.
    By that, we'd have an idea if Windows 7's drivers and system is broken. You can try it out on a
    flash drive if you so desire.

    • Leave it running for some time and report your results.
  • Looking at your bugcheck it's likely that a memory corruption event was triggered. Though a driver could be causing the memory to be borked, but we're usually suggesting a memory test before moving forward. Do a scan with Memtest86+. Memtest is a scanner that'll check your sticks for errors.

    warning   Warning
    Note that the below instructions may break your WARRANTY rules. If you're unsure check manuals, separated warranty papers, stickers on computer for secure permission.

    To ensure that we'll know if it's the slots on the motherboard that's broken, or the sticks itself - we have a little procedure we'll recommend. Remove 1 stick, scan the other with Memtest in the current slot. After 7 passes, move the stick to another slot and scan, and so on and so forth until you've scanned all the sticks, and all the slots, one by one.

I ran the memtest86+ scan and it came back clean. I have a laptop so getting to the motherboard to test the slots would be a real pain, and I don't really feel comfortable doing it.

I am currently running Unbuntu 12.04.1 to see if the problem still occurs.

No, then you shouldn't do it. It wouldn't be the issue.

Good luck in Ubuntu.
