But Ron and you have all the clues. Did this happen on a fresh install of the OS too?
Just an idea. A recent post had a member complaining of lockups and while I didn't nail it directly it was an out of date BIOS and their SSD drive. It was a confuser because they didn't tell what else caused a lockup but in the end it was "another one of the usual SSD problems."
To figure this out, you may have to get someone like Mark Russinovich to peer into the machine. Read what he does with this Slow Logon mystery at http://blogs.technet.com/b/markrussinovich/archive/2010/01/13/3305263.aspx
Now, given how Russ approached that, do you have folk around you that do such work?
After doing everything that Ron Lewis from Malwarebytes
said I still have the same problem with Malwarebytes.
The only difference is that I can manually bring up Malwarebytes after the computer boots up and Enable the protection but then the computer locks up and I have to reboot the computer
