It looks like you've got a Bug Check 0xF4: CRITICAL_OBJECT_TERMINATION. The 0x3 in Parameter 1 indicates a process (rather than a thread) crucial to system operation has unexpectedly exited or been terminated.
If you look in the "Details" tab of the Properties of your OCZ Vertex3 SSD in Device Manager and select "Physical Device Object Name" for the Property in the drop-down box, is \Device\Ide\IdePort0
displayed as the value? If so, I suspect your SSD is involved. If I had this issue, I would run a CHKDSK C: /F /R to confirm the file system on it is sound. If it is, I might then suspect the SSD is faulty. See http://www.sevenforums.com/crashes-debugging/186947-out-blue-bsod-0xf4.html
I would probably attempt to install Windows 7 on a parttion on the HDD in a dual boot configuration and then boot into it just to see if it resolves the BSOD's.
Some threads (http://www.bleepingcomputer.com/forums/topic439748.html
) mention the possibility of a virus corrupting i8042prt.sys, but I suspect your clean install of Windows 7 Ultimate makes this unlikely (although not impossible).
i8042prt.sys is typically involved with the keyboard or mouse. Are you using an external keyboard or mouse?
You could google with keywords "BSOD" and "0xF4" as well as "\Device\Ide\IdePort0" to see other threads with similar issues.
