Another BSOD

After a week of no problems I put the drive back in the original system. I had a couple problems with explorer.exe not responding but no BSOD yesterday. Today I got up for a cup of cofee, and I came back to a BSOD. The minidump says: "Probably caused by Hardware"
I'm pretty convinced that it is something with the hardware on this laptop, although I'm not sure what to tell Lenovo when I call them back. I ran PC Doctor as they requested and it passed all tests several times and they like to have an error to point tootherwise they want you to reimage..blah blah blah.
If you don't mind, please take a lok at the dump file and see if you notcie anything. I noticed something going on with NAVEX15.SYS which Iknow is part of Symantec AV, but I'm not sure if this is part of the problem.

0x8E error and says simply hardware (which are almost always the cause for these errors but sometimes it can be due to drivers).

Question: Was this laptop running fine with another harddrive in place?

Also, disable Symantec; I would say do a full uninstall but I gather that since this is a company machine Symantec was preinstalled. Are you getting any more BSOD?
