I haven't seen Driver Verifier is on, can you please enable it so that we can know if there are any faulty drivers. Also, Mcafee is there, make sure you uninstall it as Jonathan King suggest to eliminate the cause.

I apologize I did not see the post regarding unistalling Mcafee. I will be happy to do that. But to remain protected, what should I do?
I do have Macfee Enterprise from the college I attend and can install that if needed.

Sorry about missing the Microsoft Security Essentials.

I had just done the following in this order:

1) Removed Mcafee using the tool provided
2) Rebooted as requested to complete uninstall
3) Installed Microsoft Security Essentials
4) MSE download latest update
5) MSE now runnig full system scan
6) Uninstalled Quickset in case Mcafee caused install issues
7) Reinstalled Quickset
8) Enabled driver verifier using options
create custom settings
select individual settings from full list
select all except low resource simulation
select all drivers not from microsoft

Anything I missed? Should I wait now and see what happens?

Ok here goes. I will let you know and thanks

It crashed today while I was dismounting my external Sata drive. I haven't done anything yet, but here is the whocrashed report:
