Hello, I need help. Find is crashing constantly, even in safe mode

Question

Good evening.  I have a term paper to write, and I have several more seasons of the West Wing to finish.  With finder constantly crashing I am able to only get one of my objectives complete.
I am not getting any warning, or message that it crashed.  But as I try and use it I watch as finder reboots itself. (once per minute, plus or minus 30 seconds).  All of my files are in google drive via finder, and that may somehow be related.
Also of interest is that finder is crashing even while in safe mode. 
Also, earlier today my time capsule stopped putting out any internet feed for 30 minutes.  Then it randomly started working.  I had even called the internet provider to have them diagnose why the modem wasn't working... and they told me that it was the router!  Perhaps the two are related somehow?
Help!

Answer 1

Make sure you have a backup.
I don't think it's your router.
If the Finder crashes persist in safe mode that means that the problem is in OS X itself.
The next diagnostic step would be to create a test user account in System Preferences > Users & Groups.
if Finder is stable in the test user account then you know that the problem is within your user account.
if the problem is within your user account then you can either
try to fix it (boot into your recovery partition {command R at restart}, and use disk utility to repair your HD and permissions)
copy your documents over to the new account and use the new account instead. And delete the previous account.
If the problem is not your user account, then it is in OS X itself (above the level of your user account)
try repairing your HD and permissions from within the recovery partition
if that doesn't work, reinstall OS X over your current installation with the Mavericks combo updater (your post does not say what version of OS X you are running but I'm assuming it's Mavericks because that's what discussion you're in). OS X Mavericks 10.9.4 Update (Combo)
I would avoid Google Drive and use Dropbox instead.
