BSOD After cold boot

So apparently you are having this issue over years.

Some HP bloatware are causing the issue, as the crash dumps report. It is called the HP Mobile Data Protection System Disk Filter.

Code:

hpdskflt    HP Filter    c:\windows\system32\drivers\hpdskflt.sys    Kernel Driver    Yes    Boot    Running    OK    Normal    No    Yes

I'd recommend you to Clean Up Factory Bloatware, with a special reference to Point #13

13. Consider a Clean Reinstall - Factory OEM Windows 7 which is often better than getting a new computer considering how pre-installed bloatware can corrupt Windows 7 even if it's completely cleaned up.

Let us know how it went.

PAGE_FAULT_IN_NONPAGED_AREA (50)
Invalid system memory was referenced.  This cannot be protected by try-except,
it must be protected by a Probe.  Typically the address is just plain bad or it
is pointing at freed memory.
Arguments:
Arg1: fffffa81081b8380, memory referenced.
Arg2: 0000000000000000, value 0 = read operation, 1 = write operation.
Arg3: fffff8000348ae90, If non-zero, the instruction address which referenced the bad memory
    address.
Arg4: 0000000000000005, (reserved)
