aqscithe, you pointed the issue out rightly. It is iAstor.sys, Intel Rapid Storage driver.

Probably caused by : iaStor.sys ( iaStor+496b0 )

And that is a problematic version installed here.

Download and install this particular version of Intel Rapid Storage only.

It appears to be a factory install by Dell? I'd recommend you to Clean Up Factory Bloatware, at least Free up the startup.
  1. Click on the Start button
  2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
  3. Select the “Startup” tab.
  4. Deselect all items other than the antivirus.
  5. Apply > OK
  6. Accept then restart.
Let us know the results.
