Hello Halloworld and welcome to Sevenforums.

To be able to help you, we'd need you to attach some files in order for us to analyse your crash. The below link will guide you through some steps for catching these files. If you have any questions just ask us.

Hello again.

BSOD Analyse

Suspecting corrupt OS.

SFC /scannow
We usually ask people to do this command to check if Windows is corrupted. It's the most common one used to check if the Windows files are corrupted. If it'll find errors, it'll restore them.

   Tip

If you're having a custom customization layer on your Aero, it's likely to get restored to default.

Press Start | search 'cmd' | Right-click it
| open as Admin | type SFC /SCANNOW

Further BSOD Analyses

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: fffffa8c07385feb, memory referenced.
Arg2: 0000000000000000, value 0 = read operation, 1 = write operation.
Arg3: fffff800030b2e85, If non-zero, the instruction address which referenced the bad memory
    address.
Arg4: 0000000000000005, (reserved)

Usual causes: Defective hardware (particularly memory - but not just RAM), Faulty system service, Antivirus, Device driver, NTFS corruption, BIOS

Troubleshoot
Looking at your bugcheck it's likely that a memory corruption event was triggered. Though a driver could be causing the memory to be borked, but we're usually suggesting a memory test before moving forward. Do a scan with Memtest86+. Memtest is a scanner that'll check your sticks for errors.

   Warning

:info: Note that the below instructions may break your WARRANTY rules. If you're unsure check manuals, separated warranty papers, stickers on computer for secure permission.

To ensure that we'll know if it's the slots on the motherboard that's broken, or the sticks itself - we have a little procedure we'll recommend. Remove 1 stick, scan the other with Memtest in the current slot. After 7 passes, move the stick to another slot and scan, and so on and so forth until you've scanned all the sticks, and all the slots, one by one.
