iMac randomly restarts daily

[m021478]

Over the last couple weeks or so, without any warning my iMac abruptly and goes black and then restarts for reasons unbeknownst to me.

I've copied and pasted the crash report below. Perhaps someone can help me make sense out of what's going on and how I can resolve the issue? Thanks!

Try this first: Create a new user account and run that for a while to see if the restarts happen.

Your last Kernel Panic occured when the system "saw"

com.Cycling74.driver.Soundflower 1.5.1
com.logmein.driver.LogMeInSoundDriver 1.0.3

I would recommend first updating those apps and if necessary uninstalling by following the developers instructions.
