BSOD on occasional start up, error 0x0000007a

[LemonPower]

Unexpected Blue Screen of Death's occur on occasional start ups, if the computer boots normally without a crash I experience little to no performance issues. However when it boots with issues the event logs state that the WUDFRd driver is unable to load successfully for

WpdBusEnumRoot\UMB\2&37c186b&0&STORAGE#VOLUME#_??_USBSTOR#DISK&VEN_GENERIC&PROD_CF_CARD_READER&REV_1.00#058F63606476&0#

which is followed by another log seconds later that says that it's unable to find the assembly item Microsoft.VC80.MFC,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="8.0.50727.762"

The last system crash occurred at (GMT +1) 15:12:36 op ‎10-‎8-‎2013. The two above seem to be the only thing the system actually logs before killing itself. I have no idea.

Requested information attached below.

Posting off my secondary computer.

As I was going through my desktop my monitor suddenly shut down and the sound cut out rendering my computer unresponsive. I turned it off by holding the power button before restarting it moments later. Doing this caused the same events half-way during start up. After restarting it again it said it couldn't start windows and I did the recommended action to have it run startup repair after which it did the same again. I left the computer off now to avoid damage, I have no idea what's causing this.

   Tip

• :info: Pay close attention to part 3 of the tutorial "If you have errors"
• :tip: Test the RAM with Memtest86+ for at least 7-10 passes. It may take up to 22 passes to find problems. Make sure to run it once after the system has been on for a few hours and is warm, and then also run it again when the system has been off for a few hours and is cold.

KERNEL_DATA_INPAGE_ERROR (7a)
The requested page of kernel data could not be read in.  Typically caused by
a bad block in the paging file or disk controller error. Also see
KERNEL_STACK_INPAGE_ERROR.
If the error status is 0xC000000E, 0xC000009C, 0xC000009D or 0xC0000185,
it means the disk subsystem has experienced a failure.
If the error status is 0xC000009A, then it means the request failed because
a filesystem failed to make forward progress.
Arguments:
Arg1: fffff6fc400063a8, lock type that was held (value 1,2,3, or PTE address)
Arg2: ffffffffc0000185, error status (normally i/o status code)
Arg3: 000000008ddcd860, current process (virtual address for lock type 3, or PTE)
Arg4: fffff88000c75008, virtual address that could not be in-paged (or PTE contents if arg1 is a PTE address)
